00:00:00
thank you very much for the introduction and good afternoon ladies and gentleman
00:00:05
no i have to pleasure uh to tell you something about and nobody applications refer to a talks
00:00:11
about interior so the interior uh materials you see
00:00:15
you can touched and you can feel them
00:00:18
but for and about a applications you hardly know that they are existing in
00:00:22
the car and i try to get your emotion on the spot
00:00:25
my presentation is about the success of non load materials for like
00:00:29
great and acoustic efficient components in on the body application
00:00:33
first i give your short introduction about about our company then
00:00:37
i will talk about requirements for on the body
00:00:40
systems and there you will see there are many requirements
00:00:43
that are mary contradiction rick contradicted their requirements
00:00:47
and therefore it is hard to fulfil these requirements just put a
00:00:51
one material therefore multilayer material classically number of materials our fate
00:00:58
i will show you three of these materials and make some comparisons and concluding remarks
00:01:04
rushing group is a family owned a company founded in eighty
00:01:08
twenty two so nearly two hundred year old and
00:01:12
um power divisions are industry medical and automotive
00:01:17
about half of the turnover remake which uh automotive the division
00:01:22
we are uh our global supplier for uh for these parts and therefore we are um
00:01:28
find burnt light especially were also our customers are
00:01:33
and coming to the requirements of a nobody components here you can see it
00:01:37
on the buddy system off a b. m. w. uh seven serious
00:01:42
the main component a requirement is ergonomics because with a good
00:01:48
ergonomics you can improve for your fuel and the
00:01:51
mission saving of your vehicle and a forever deny mixes the driver that means you cover more and more
00:01:57
of your car and while you're covering more and more of your car you introduce
00:02:02
additional weight to this car therefore it is very important that you introduce lightweight materials
00:02:09
the second uh and requirement we have heard already today for
00:02:14
the interior also is acoustic acoustic performance
00:02:20
the car you can improve it by the um by the and and nobody
00:02:25
covers when you have absorbing or damping material so you can play
00:02:30
as we just heard in the previous talk about interiors it's the same as system you
00:02:34
have absorption you have damping of combination and with this you can improve that acoustics
00:02:40
contamination that means the dirt and the snow uh of of the parts corrosion corrosion of the
00:02:47
body invite most of the budding lights are still in metal in steel which can corrode
00:02:51
you are a body invite structures goes with other medium so we have
00:02:55
different approaches on that or even with the plastics are uh
00:03:00
yeah composite materials about corrosion is not so uh the important you have a um
00:03:07
trash requirements for example pedestrian impact so the front part of your car has to have
00:03:13
a certain stiffness or can be from a a certain material the management that means
00:03:19
you have still to come bastion engine they are you generate heat you have to
00:03:24
pull components you have to get a heat out of your uh engine bay
00:03:29
you have um the exhausts a pipe still going for a couple of years in future there
00:03:35
you have to have the right material you have to protect your components in the car
00:03:40
how must be robust if you're driving on the bed wrote the the part should not be damaged or fall off
00:03:46
temperatures the billy to you know we are working all the volume as a
00:03:49
polymer fibres uh at some certain temperature there will be a um
00:03:55
uh some yeah degradation and therefore you have to select right materials
00:04:00
and flute and absorption that means uh if you drive in the rain
00:04:06
part can absorb water and get heavy so this is of course not want
00:04:11
going back about thirty years uh we had to first material which has been used in on
00:04:16
the but the application this mature disclose called classmate reinforced channel plastic the g. m. t.
00:04:23
and it has been developed at that time from russia language that at that time a different name and
00:04:29
yeah we can see again the first uh a non woven application that is the glass fibre mat
00:04:36
the glass fibre mat is generated by needle punching of cut to
00:04:39
last forever so you first uh produce a mat and
00:04:42
then you have a double pal press where you integrate this with the polymer in the most cases this was polypropylene
00:04:49
and you uh produce sheets the sheets you can see on the right side blue
00:04:54
you heat up the sheets uh and you have a press hydraulic press where
00:04:58
you uh press the parts that that's what we do on that
00:05:05
uh_huh
00:05:06
what
00:05:08
now it works
00:05:14
sell the sister g. m. t. a part production process you have this uh glass
00:05:20
fibre reinforced map which the the seated up in an oven twenty thirty degrees
00:05:28
you place it in the mode you closed remote there cooling time is cut out here in the video
00:05:34
but anyway this is the process you have a flow of material and you generate the part
00:05:40
this product was it three series b. m. w. engine under she looked
00:05:43
and it has been produced about four hundred thousand parts per year
00:05:48
part has the size of about point seven square meter which is not a very large and
00:05:53
uh and therefore will see what we'll have in future larger parts which are higher
00:05:58
sizes and therefore the need for the lower weight and is necessary
00:06:04
so here again uh the g. m. t. had this great care unit
00:06:08
area about uh more than two thousand grams per square meter
00:06:12
and in the upcoming yes they have been developments to reduce dissuade
00:06:18
uh yeah significantly to about one thousand grams per square
00:06:22
meter so in two thousand nine we reach
00:06:25
this goal but it doesn't mean that we have stopped the development of material after that
00:06:30
it's just that the one thousand grams per square meter is sort
00:06:33
of bottom line of material in the and everybody uh application
00:06:37
we started two thousand three richard b. m. w. with the material from uh
00:06:41
asked alone now today humble from us it's called that's there's a polite
00:06:46
but you didn't have acoustic performance and in two thousand
00:06:49
six bustling has developed its own material called civilised
00:06:53
which then had this acoustic performance and even wait
00:06:57
saving properties in regard to the previous material
00:07:01
here is a cross section of um our l. w. r. t. v.
00:07:05
we have a three layout uh s. sandwich structure with different
00:07:10
glass fibre content in the skin in the core layer
00:07:13
and we produce a this product uh with the las
00:07:19
a troll says over the cutting process i know you're all familiar with these processes so i don't have to go
00:07:24
so much in the tape and here we have a regular unit era of about one thousand
00:07:29
four hundred grams this is our standard material where we which we propose to every car
00:07:35
manufacture uh for uh let's say for entry if you want
00:07:39
to use lightweight uh materials in the under body
00:07:43
and the big advantage compared to a compact material like injection molding are g. m. t. is
00:07:49
it everywhere on your part you have the same way per unit area in this case one thousand four hundred grams but
00:07:54
to can have it in different thickness s. and with a
00:07:57
different witnesses you will have different uh um acoustic performance
00:08:05
so you're gonna detail to have glass fibres you have polypropylene fibres
00:08:09
and you have a needle met so the needle punching is a
00:08:12
very important step of your product because with a needle
00:08:16
function you can generate the lifting of two material so when you get up the material
00:08:21
the glass fibre remember that initial stress situation and therefore
00:08:25
the material will go up and increase their eight
00:08:28
and then um we'll have a a hate for for production with the different thickness is
00:08:34
so i've already talked about this multi functionality of the requirements
00:08:40
and therefore we are using non woven city no why the uh
00:08:45
a weight range and of course to purchase this uh materials on the market
00:08:50
you go from about fifteen grams per square meter to about four hundred
00:08:54
grams per meter and most of these materials are adjustable polypropylene based
00:08:59
it can be could be either aspen bond or needle plunged
00:09:02
depending on the weight or on the application me
00:09:06
and the functions are yeah look and feel maybe not for under body you will think
00:09:12
the the and the body cover nobody will look and nobody a real field but
00:09:17
you know the workers they have it in the hand and if you're looking on on
00:09:21
the bentley a continental uh you will see in the back to relief user
00:09:26
some part of it you can see if you look a little under the car or a big yeah
00:09:33
issue in and nobody is is this don't chip performance them to performance you can uh
00:09:40
play on it depending on the the stiffness of your material and uh
00:09:45
and the combination of your material so a polyester non woven with a three four hundred grams per square
00:09:51
meter uh almost a fulfils all customer requirements in
00:09:56
the stone cheaper performance also for processing um
00:10:01
if you are heating for example with the contact eating you need
00:10:05
a different uh processing a non woven there's a cover layer
00:10:10
in this case we are using mainly a polyester and for acoustic optimisation
00:10:16
a different uh materials that can be used and there's another uh
00:10:22
thing that that will live and i drove public or coating on which can applied on the non moments
00:10:27
for uh applications under the engine where there's only one hundred probably uh is is needed
00:10:34
so here's a typical example of a such an um material for
00:10:39
an nobody application this is called the the light for
00:10:43
four is only the the name for a development and uh
00:10:47
the way community area is one thousand one hundred grams
00:10:50
and we have the processing an acoustic layers on top we have
00:10:54
the stone to performance and acoustic players coming then we
00:10:58
have the core layer of glass p. p. for stiffness also or caustic and we have some other processing like
00:11:04
of course you can make symmetric a built up or estimated buildup is
00:11:08
is uh are depending on what your role uh in your and
00:11:14
than development here is the uh the parts we are making it this
00:11:19
is um the undivided cover of the mercy that's that's class
00:11:24
one part has the size of a one square meter so we have
00:11:28
to square meters um under the car and the weight is
00:11:32
one thousand one hundred grams per square meters of about two point
00:11:35
one kilograms in wait for this acoustic uh i'm element
00:11:40
since the message assessed last has a very high uh acoustic the amount we also have
00:11:45
additional uh absorbers on these parts and in this case it's also a number of material
00:11:52
we call it the felt in the back type because there is the number one
00:11:55
which is covered by us in a layer of um yeah last week
00:12:02
this is the absorb
00:12:04
so i'll wait saving is a big issue aim for
00:12:08
a cost to debut effort already and are works
00:12:13
we could uh get a a minus fifty percent in
00:12:17
the b. m. w. x. five serious from earlier
00:12:20
twenty eleven to model your twenty thirteen so that the the latest one and just uh by
00:12:27
almost using the same design of the part but using the like wait a reinforced plastic material
00:12:33
and the six kilogram in weight of course um you have also different
00:12:38
cost situation between these two uh parts uh in in total
00:12:46
about uh acoustic performance uh of non woven survey upright
00:12:50
already today we measure this in the alpha cabin
00:12:53
you can the higher the value it is uh the better it is
00:12:58
uh on your this is the kind of absorbing material which need
00:13:02
to stop support so the support can be either g. m. t.
00:13:05
and nobody cover or a l. w. kept the undivided cover
00:13:09
and you can see depending on the thickness of your material and also the composition of your
00:13:14
material you can vary in a very wide range and this is of course uh
00:13:20
our goal to find out together with our customer which is that
00:13:24
correct range what do you want to have which frequencies
00:13:27
do you want to absorb which is your package uh what
00:13:30
wait can you introduce so it's a very wide field
00:13:35
i also have to mention a non woven india nobody um um well
00:13:41
yeah application from our company here in switzerland you know very well
00:13:46
the material is called r. u. s. b. to ultra
00:13:49
silent and it's uh yeah non moment without
00:13:53
glass fibre so we're doing a non woven with glass fibres they are doing without plus fibres
00:13:59
they are also in the market so uh well we divide the market upon us and with some of us
00:14:07
a in this
00:14:09
we have seen the transition in us where the started the fourth monday or with them in their
00:14:15
called fort fusion with the p. p. glass fibre
00:14:18
based non mormon and later on during um
00:14:22
during the running process this has been replaced by a pulley polyester based on
00:14:28
of course we have some issues uh they are with these parts one of the issues is uh whatever
00:14:33
absorption i've mentioned it already you know if you have a compact material no water or uh
00:14:39
will be absorbed if you have a glass a p. p. material l. w. r. g. type is a polite type
00:14:45
you have somewhat of absorption but not as high as with the non mormons or your
00:14:51
we can see a water absorption zap to two hundred percent which
00:14:55
of course uh the car gets a heavy then and
00:14:58
it's not the two hundred percent uh in wait uh where the the customer is not so happy with
00:15:04
but it's the drying time so if you have something you can see here you have
00:15:07
more than one hundred percent uh water absorption but it dries within seven dollars
00:15:12
it's quite comfortable but if it doesn't dry within the seven now so
00:15:16
it's the last fifty percent of weight after the seven hours
00:15:19
it's it's not okay and therefore we have to develop a such kind of materials where
00:15:24
we have this trying time short or at least a water absorption not so high
00:15:30
okay if you do now this eh combination of all these three materials i've presented to you to g. m.
00:15:35
t. the glass it p. p. l. w. r. t. type and a non woven without glass fibre
00:15:41
you see the advantages of the l. deputy type materials in the weight so
00:15:46
between one thousand and a twelve hundred grams uh of material
00:15:51
and also in in the processes that you have advantages because of the low pressure process you have
00:15:58
you can make multi cavity to us you can make a large parts in one two will or can make
00:16:03
three or four or even more parts in one uh to
00:16:07
depending how big your presses are and uh the
00:16:11
you have different extreme operations like uh what it that lays
00:16:16
a punching or even follow volumes a pinch edge
00:16:21
and if you do the comparison regarding the other uh
00:16:25
them around properties you have in these materials
00:16:30
you can see here uh the last five or p. p. v. uh based
00:16:34
material has some advantages regarding the water absorption and also to eat performance
00:16:41
but uh uh as you see in the market all of these three
00:16:44
materials are still uh existing and they are uh going parallel
00:16:50
but uh really belief in in future we will have
00:16:53
more lightweight materials under the car switch on
00:16:56
especially developed for the whole way um and especially
00:16:59
have uh this uh characteristics the customer needs
00:17:04
no i'm coming to and short summary of my uh um um presentation
00:17:11
so the lightweight and uh outstanding acoustic properties as well as
00:17:15
better cost performance other drivers to use the number
00:17:17
one based materials for on the body applications and we
00:17:20
do this for more than thirty years uh successfully
00:17:25
if you try we we see more and more on the body parts uh to improve the ergonomics
00:17:30
into reduced emissions so even higher need for lightweight
00:17:34
parts thank you very much for your attention
