Potential of nonwoven-based structures for the automotive industry
Dr. Bernd Gulich, Saxon Textile Research Institute (STFI)
Tuesday, April 4, 2017 · 3:59 p.m. · 24m 32s
Nonwoven-based structures are used in many applications in the automotive industry. STFI has conducted collaborative research with the industry, producing results such as three-dimensional stitch-bonded nonwoven type “Multiknit”, now used as laminating material for upholstery. Further research concerns the application of bio-based fibres for car interiors. Continuation of this research work involves the partial substitution of natural fibres through recycled carbon fibres and thereby achievable effects in weight reduction.

hi good afternoon ladies and gentleman and thank
00:00:04
you very much for their kind introduction
00:00:08
i would like to give your presentation about about that potential of marble from
00:00:12
base structures but automotive industry and we have a lot a lot
00:00:18
about these uh structures this afternoon and i think my presentation is a a
00:00:23
good a closure to this uh give presentations we have up already
00:00:31
at first i would like to to uh give you some impressions about our institute the uh steve
00:00:36
isaacs and text that research institute income it's our profile you can see in this light
00:00:43
uh the uh as remain columns in or uh justify are the centre of excellence
00:00:49
in ovens yeah i come from the centre of for text highlighted engineering
00:00:55
is a very new and young part of our institute and the innovations and or
00:01:00
technical tax status of course we have a department for services and
00:01:06
uh like a credit it a test laboratories and certification departments and
00:01:10
so on and a centre for the transfer of our results
00:01:18
the coming to the centre of excellence in one opens what our minefields of excellence
00:01:23
this or that forming about bonding we have nearly all technologies
00:01:28
in dispute them in our institute is often when a one a a customer asked me
00:01:35
but uh i told him we have nearly all technology is and he
00:01:39
asked me for chemical bonding and i have to say this
00:01:44
just the technology we have martin our insecure what we can do but it's not a very common
00:01:51
so we have a that after treatment of number opens a month
00:01:55
opens recycling the this is where i come from mainly
00:02:00
the last you know the last thirty years i deal with um uh the normal from this recycling and
00:02:06
non woven send a it's very familiar them that the guys out these of those skills of research
00:02:13
we have also tailor made product developments testing and certification services
00:02:19
connecting with our developments and uh a new centre for light text are lightweight engineering
00:02:27
uh yeah make use of research into centre are the recycling uh
00:02:31
to reuse of textile high performance materials like carbon fibres
00:02:37
the processing of text i there's especially from carbon fibre based by
00:02:41
the use of a modified cutting and during the technologies
00:02:47
and the year uh can also about forming that recycling or high performance fibres
00:02:53
and according technology old a random number of them technology you
00:02:57
can see the right hand side and the bottom picture
00:03:01
yeah you're uh you can see it can get an impression about
00:03:05
the the russians we have installed on the right hand side
00:03:09
according device and the left inside and the only machine and in the centre of the picture you concede across the pro
00:03:16
and ah behind the cost of our we have a new budget machine pointing demand and
00:03:22
also stitch one thing machine for the the intended meant by by means of struts
00:03:29
that's it
00:03:33
so i come to of frost the example of our investigations as um
00:03:39
there are more of a older investigation that means the project was finished
00:03:44
yeah last year a buyer based materials full power into yours was um
00:03:51
in hey you found it a a project to call you people car
00:03:56
and the project project aims wrote develop green materialist of greater is likely plucky
00:04:03
um and text as substrates from uh uh we knew yeah but we knew it the resources
00:04:11
so the you synthetic fibres from p. l. r. uh p. l. it very very it's and natural fibres
00:04:17
and the our aim was to uh fulfil the
00:04:20
current technical requirements but if this new materials
00:04:26
so the basis five up to par development was part of
00:04:30
t. i. takes institute coming from a clay in spain
00:04:33
and they have a that done a lot of adults uh to
00:04:38
to bring the the p. l. a. five us into
00:04:41
uh i'm a former that makes him usable for automotive uses a
00:04:48
bit put a a as they add a lot of substances
00:04:52
and at the end you have a lot of off a fibre pipes to test him in our institute
00:05:00
so we have to go and also uh of the part of fibre developments
00:05:06
as you can see the p. l. a. five hours was a standard uh below if i
00:05:10
was a standard major works fibre and they at
00:05:14
a lot of substances to these fibrous
00:05:20
the open up in this project was to uh create a door panel
00:05:24
as and demonstrate all for for this uh uh uh materials
00:05:31
propose a that's really out sartre was the consisting
00:05:36
of a natural fibre composite as supporting logo
00:05:40
i'm here with the number of one of of number to the
00:05:45
as soon as we to mention need a bunch on over and as a soft
00:05:48
the so called soft touch arrow and numbers reason to go to it
00:05:53
oh fun fabric what is um materials uh there
00:05:57
are processed from from natural paste a fibrous
00:06:05
the natural fibre composite uh consists of and planned off a fifty per cent
00:06:10
of ham fibres and fifty percent of special p. l. a. fibre
00:06:15
does lead to mention me to punch was the consisting of
00:06:18
one hundred percent of the late fibres and the decorative
00:06:22
open public first made from coloured below a filament yawns
00:06:27
this world was the part of the i. t. a. in aachen
00:06:34
so you know that you can get an impression about uh the as a separate
00:06:38
fibre types that we find out uh at the end of the project
00:06:44
and the uh special interesting is the are the melting points of these
00:06:48
fibres equal to the spiel a fibrous the that the melting point
00:06:54
not in sixty four this was the so called p. p. like fibres
00:06:59
and the formatting the fire melting point at two hundred and seven
00:07:04
it tina decrease uh the courts um the t. t. like fibres
00:07:10
so only to to compare uh this uh to a special kind
00:07:15
of five was with the fibres normally used in this process
00:07:20
so the v. b. use to the p. p. like fibres in the model
00:07:24
part for the bit to open of the and and we used to
00:07:28
the the b. t. like fibres for plus the upholstery material here
00:07:33
we have two uh different fibre finest blend of fibre finances
00:07:38
a lot of the same uh consistency and the the
00:07:44
has a point being fibre indeed and the and the stuff touch they'll be uh at the uh at beagle
00:07:51
file uh by compliment fibre of the for made of polypropylene uh made of p. l. a. fibre stuff
00:07:59
melting points the one hundred and sixty three degree in the sheet and and
00:08:04
yeah two hundred and fifty and a decrease in the core
00:08:10
to develop that below five hours fulfil the processing requirements to be used in
00:08:15
the foreseen mumbled instructions this was the result the got in our investigations
00:08:23
and then the it gifted material to uh they're doing the industrial park
00:08:29
no for for testing and here you can see the test results
00:08:33
uh and you can see the uh to get an impression of the phases of our customer
00:08:39
mostly the looking very well so that means the the uh uh get to the
00:08:47
he get aims of the uh the investigations if our materials on the
00:08:53
right hand side you can see the our demonstrate or the
00:08:59
in in in in in complete tore into our panel so
00:09:06
that we can say the we have the the meat to aim of the project
00:09:15
so in the next part of my presentation i would like
00:09:18
to show you the potential of a problem fibres either
00:09:24
the best if i uh stealing of carbon fibre since two thousand and five you have a lot of you have done
00:09:30
a lot of investigations and the possibility of long carbon fibres
00:09:35
that means uh these are five also not filaments so
00:09:41
the first step the the but we have done was to cut drawings
00:09:47
into a stable fibres as raw material on the to to have
00:09:52
the steeple five also i love the at this time to twelve thirteen years ago
00:09:59
so in the second step uh be cut a carbon fibres was
00:10:02
starting from a recycled composite parts uh after uh by releases
00:10:08
our objectives was uh there are the fabrics might of recycling
00:10:13
problem fibres layout right now so it's by and mechanically operated that formation
00:10:19
you can see the pictures uh twelve years old pictures is a very uh
00:10:25
would the harding device of all cross leper and the uh
00:10:30
uh that feeding the the one hundred percent problem five about into a stitch bonding machine
00:10:37
i mean by the uh as you have seen before we are very better equipped with
00:10:42
new machines and this new picnic and we are able to process this fibres
00:10:49
into my movements very though
00:10:52
in this light you can see the sorting categories of carbon fibre waste we have a try paste
00:10:57
without any metrics this is also the the the
00:11:01
material we can process with our technique technology
00:11:06
we have that faced the data networks is not you out and we have costly to matt based
00:11:13
but uh to a matter exists all base you want this this could
00:11:18
be for instance print production rejects or end of life based
00:11:25
as i told you we uh we can process only did try paste and uh uh that based
00:11:29
and was lying placed a is needed to to go into a as a process is to
00:11:35
the the ring day and metrics out of the uh structures
00:11:40
for instance with uh the muscles of to apply releases
00:11:45
so our present activities the i. r. and resist the inverse refute of recycling
00:11:52
is the recycling of try based by using to and tearing process
00:11:57
and the possibility optimisation of carbon fibre softball polices
00:12:02
this kind of five versus a very difficult to process because there's
00:12:07
no nothing as the um the the problem no no the
00:12:14
agent on on surveys like you can find on on the top one five
00:12:19
hours uh uh to use them from from a try production based
00:12:27
the uh uh do some investigations in separation
00:12:31
between us different physical methods to separate
00:12:35
that carbon fibres and non carmel and um and fibre material is for
00:12:40
instance to stewing stewing sweats you can find in in in a separate the
00:12:47
fabrics the carbon fibre fabrics this means to remove affixed anise fibrous
00:12:55
be doing we're doing a investigations and blending
00:12:58
of a recycled carbon fibre sleeve also
00:13:01
fibres as ballast polypropylene fibres as an oral polyester fibres as metrics five us
00:13:08
and as you will see later the the test the effects of natural fibres
00:13:15
in the future but formation um be a are able to use the
00:13:19
the cutting process of last fibre to match and uh since
00:13:25
and a half euro we are able to uh use uh an
00:13:29
l. a. process uh to get a random that formation
00:13:33
be a or b. of doing investigations the outer in to identity funding muzzle it's like
00:13:40
spun lays spending a and what we are doing are also is a two
00:13:47
a form these recycled carbon fibres into his liver and a young formation yeah
00:13:56
a formation yes
00:14:01
so the problem uh five always three treatment as i told you use a a modified uh
00:14:08
caring process coming from from normal textile recycling processes
00:14:13
but uh it's a specialist some special things like that form of the pins and uh speeds of the
00:14:20
the process and in in the pictures you can see the material before
00:14:25
the process and after the process during process and then the
00:14:29
speech on the right hand side you can see such as ewing's read
00:14:32
the python but yes that's right and this is uh sometimes
00:14:37
so uh a good for the customers to have such material in the carbon fibre plant
00:14:47
we are able to uh uh to get a five years but
00:14:51
never which lines of a sixteen millimetres that means the
00:14:56
the eighty five percent of the pretty cut lengths we have uh
00:15:00
playing on the material and this report throughput yeah volumes
00:15:07
are in an area of the around two hundred kilograms per hour rate of walking that if
00:15:14
and in my opinion no and i will opinion
00:15:17
this is uh it's and economical interesting saying
00:15:21
to well if such a process on the market the can find another
00:15:25
process but is this the does the throughput is not so high
00:15:34
so the and the field of that formation we are able to process uh
00:15:38
a long but not endless carbon fibre split it means of recording
00:15:42
principle and uh also by the means of ellie principle
00:15:47
you are able to process a one hundred percent cotton fibres
00:15:51
into a normal buttons or of course it's also possible
00:15:56
plans with also five hours in this natural fibres or they take pride was and the used entanglement
00:16:03
by means of that needed punchy and stitch bonding process as you can see the
00:16:08
two printed this in the pictures below and as i show you later yeah
00:16:15
the uh use also day i do and thank him for them
00:16:19
and think in and of the carbon fibre mobile that's
00:16:24
this is the next point the couple is project the the use of fight when think it meant
00:16:30
to the cat and the normal than from carbon fibres
00:16:37
the upon the first application of the span of those uh a spineless technology
00:16:42
for consolidating of a carbon fibre mumbled runs the the expected benefits
00:16:49
are in the areas offer five orientation service quality quality
00:16:54
actually in production team production means what you can see in the picture
00:16:58
on the right hand side the dust and i need a loom
00:17:03
after a processing problem fibres or as a fibrous is enormous and
00:17:09
they're using height wanting to mend you the the not get any test in in
00:17:13
in the air around the the process and in the case of problem fibrous
00:17:19
very important to have no not so much carbon fibre passed around
00:17:24
because there's a cop uh also and that big risk of electrical damage
00:17:30
so
00:17:32
but um disadvantage or the the the the as a side of this process
00:17:37
as we need to i fought for the process what the cleaning
00:17:45
so in in in this picture you can see the difference between
00:17:48
need attention span laced a a normal button it's the the
00:17:52
same sink as you can see all of the of the belief
00:17:56
as some of the small mother synthetic fibres for instance
00:18:00
the be fine found out that the intended mentor spotless technologies possible
00:18:05
trials with part of mobile than snake of one hundred
00:18:08
percent recycled carbon fibres and blends of carbon fibres
00:18:13
right on the basis plates are between two hundred a one hundred g. s. m. and two hundred and fifty g. s. m.
00:18:21
and to trying of data on weapons works very the the infrared field
00:18:29
you can see uh some uh and mechanical properties we have a carbon fibre content after
00:18:37
after all the the bringing did and not open and and books it
00:18:42
resentment rick's the around a twenty five percent and we have a
00:18:49
the from our point of view a good the properties in
00:18:53
the field of a in loose and things as strangers
00:19:00
so the the last uh now in of this uh project as the
00:19:05
c. f. blond project but uh the problem fibres else's ham fibres
00:19:11
and uh this is what i mean the for landing this natural fibres
00:19:17
coming back to to the first uh a project uh using canned as
00:19:22
uh uh uh a reinforcement fibre and b. t. v. s.
00:19:27
metrics fibres the going for out from this point
00:19:32
my idea was a duo see what's happened with uh the a substitute
00:19:38
a part of the of haven't for for the recycled carbon fibres
00:19:44
and i have first step of my project was the
00:19:48
boxes substitution of the ham fibrous by carbon fibres
00:19:54
yeah the favourite the the of one thousand six and not a compass parameter
00:20:01
this is what you can see in the in the first uh the role of this of the
00:20:06
table sixty percent natural fibres hemmed and forty percent
00:20:11
p. p. five or seven zero percent of
00:20:14
a problem five hours you can see the the ten size strange
00:20:19
and they also mechanical properties are the good enough i think
00:20:24
but uh uh see you can see also what seven
00:20:27
him the indy also rose and then then
00:20:31
i a substitute uh to natural fibres buy recycled
00:20:35
carbon fibres and didn't in this uh the
00:20:40
there twice i find found out the that that's the best way to substitute
00:20:45
fifty percent of the natural fibres that means thirty percent at all
00:20:51
of uh by a carbon fibres and now i yeah it was
00:20:55
interesting for me what's to see what's up and the in
00:21:00
the case i degrees that the debate of the fabric this this
00:21:05
was the that was the second step the reduction of mobile
00:21:09
phones basis late from one thousand six on the g. s. m. two eight hundred g. s. m. f. their favourite plant
00:21:18
yeah the results the you can see here i and the
00:21:25
the one thousand g. is um the uh the better results than the original uh
00:21:31
uh
00:21:33
separate the above one thousand six hundred the g. s. m. and also
00:21:38
with eight hundred a cheese and they have a good results
00:21:42
that means at the and a sheriff's thirty percent recycled carbon fibre solos
00:21:47
up to fifty percent data protection without a loss of mechanical properties
00:21:53
this was uh the most important reside for me i
00:21:58
didn't expect it uh so uh impressive the that
00:22:02
that i can uh bring down the fabric of up to eight hundred g. s. m.
00:22:09
so you can see is some uh a molded parts uh as demonstrating round
00:22:16
uh parts uh in the the the the parts in the right hand side
00:22:19
you can see a towel a a stand in in our uh to
00:22:28
and yeah you you are invited to to to uh uh get the feeling of
00:22:33
this parts at the the weight off of the spots is very impressive for
00:22:38
a lot of customers uh was very uh uh impressed that they already
00:22:44
about this uh to the weight difference of these parts
00:22:51
the coming today and my results in the summary at the
00:22:55
fireplace the fibres are suitable for automotive good applications
00:23:00
the treatment off by carbon fibre headlight carbon based but modify
00:23:05
tearing process is technically feasible and uh of economic interest
00:23:11
direct formation by means of one not of carting using one of
00:23:15
those and cotton fibres on forest land apostles also fibres
00:23:20
as well as the full of mechanical act tenement is technically feasible
00:23:25
products have a profile of characteristics which qualifies them to
00:23:29
be used as in c. f. r. these structures
00:23:33
uh and
00:23:36
the is need to find applications and standards for this uh
00:23:41
uh the the very new product or fields of products
00:23:49
so i i d. and acknowledgement for the for the uh three
00:23:54
the projects we have uh done and and this fields and
00:23:59
i thank you for the attention and ability as a for my little pure english
00:24:05
maybe a comparable compared with the other speakers but i hope that was uh
00:24:11
two and that was understandable for you uh i i would like to invite you to visit us and uh
00:24:19
dollar stanton uh india also all stand numbers something six thirteen i'm
