Brian,
I threw the idea out there as a trial balloon to get the discussion =
and ideas flowing. It looks like it is working. =20
To answer a few of your questions regarding my specific reasons or =
considerations for switching to euros, first one would be appearance and =
second weight reductions. Major drawback would be crash protection.
As far as a glass or fiber clone, I was thinking along the line of =
just the skin and using some of the existing rebar for support.
Josh said that if he can get some loaner bumpers and 5 orders he can =
make them too. Josh, any ballpark idea on price? =20

Subject: Re: How about Glass or Carbon Fiber Euro Bumpers?
Are you guys talking about cf/glass euro bumper skins, or the whole =
bumper? Assuming you have a proper means to attach it, a skin shouldn't =
be hard at all. There is also no reason that the entire bumper can't be =
made of cf or glass. In fact, designing similar stuff to this was my =
job about 2 years ago. The differences are that this is a serious =
structural part, and you probably can't get away with slapping a piece =
made from fiberglass or carbon chop onto the back of a nice cosmetic =
piece like some of the cf hoods I've seen out there. I mean, you could, =
but you stand a much better chance of the two parts separating, and =
using chop like that just increases the weight a LOT, and isn't that at =
least part of the reason to get this stuff? Anyway, it wouldn't be =
anything new for me to put together a one-piece euro bumper (i.e. not =
two pieces glued together after the fact), with a nice cosmetic skin, =
some serious structure to it, and mounts for the existing bumper =
brackets. Given cost considerations it might be a good idea to use some =
fiberglass instead of making the entire thing carbon, but if that's done =
right the weight can stay down nicely. Nice thing about composites is, =
once the molds are made for the required shape, the part can still be =
tailored a lot to use carbon, kevlar, glass, or paper mache (kidding) if =
somebody wants it made of that. I also have the means to run finite =
element analysis on a part like this to make sure the strength is in the =
design (yes, people in the real world do DESIGN cf and glass parts when =
they need structural strength, not just copy the old steel part. =
Imagine that! hehe)=20
Anyway, just a head's up to the list, but I'll be moving in a little =
less than a year, and setting up a composites shop all my own. Like I =
said, I used to work for a company that designed and built prototype =
composite parts for everyone from Big3 Automakers to foreign governments =
and anyone else, so I'm trained in designng this stuff and building it =
as well. I have a couple of people who want some custom work for their =
cars, and I'm planning on copying a lot of my car (SII 16v) for my own =
personal use, so once the molds are made, I'll run extras off for =
whomever wants whatever. =20
If there is a demand at that time (~1 yr or so) for a eurobumper =
complete with substructure, I can design, analyze, and build some. =
Should be light enough to make any of us REALLY happy. :)=20
Just to give you some idea of what can be done with composites, one of =
my last projects was to redesign a large aluminum tray (on the order of =
8' by 3') to hold 1500lbs of stuff I can't tell you about in a concept =
car. The aluminum tray weighed ~70lbs, and wasn't as strong as they =
needed the part to be. Our version was 47 lbs, was considerably =
stronger, and would have been lighter if we hadn't left a layer of =
plastic on each side so it could be mass produced more quickly (removed =
from molds more quickly). So now you are talking about a part that is =
30% lighter than an equivalent ALUMINUM part, and stronger, even with =
extra useless layers of plastic thrown in. I don't want to shoot my =
mouth off (more than I already have) about what replacements for steel =
scirocco parts should weigh, but you do the math.=20
BH=20

Allyn <amalventano@sc.rr.com> wrote:=20
while that would be cool, its kinda the only thing protecting the =
rest of the
car when some dumbass cuts you off / rear ends you. even with all =
the crazy
fiber-skin stuff i plan to do on the twin, i still intend on using =
'real' euro
bumpers.
