hey, i forgot to ask. you're talking doing this in cf, right? i wouldn't be interested at all if you do fiberglass. i know i'd get it broken the first time i drove with it.
I'm interested as wellOriginally Posted by Michael999

Unless it is has kevlar in the weave i think you'll find carbon fibre is more brittle than fibreglass.Originally Posted by steve0suprem0

But some reinforceing webs would be a god idea- they would take some force at the average 150-240kmh I do along Sydney streets- especially over the median strips and railway crossings where I usually get so much air the car needs wings like an 'ReX... I'm surprised someone like fukem5 hasn't chimed in and told us all how to make em out of titanium CF with some rare earth polymers from a deep rock sub-strate only found under the Amazon... LOL

Whortge are they?Originally Posted by The Bigfella
I think we are talking about reverse engineering them, not copying them outright. But it's not up to me, I'm not making them. Seriously though, I doubt Hartge need worry about cheap copies, they'd have gone out of business doing that.
Do they actually still make them for the e34?Nick

well i didn't know about cf being more brittle than fiberglass. which is interesting. i've just started today the composites section of getting my a&p license, and i'll probably learn that sometime this week.
unfortunately, i'm an even bigger idiot in other reegards. i didn't even notice this was going on in australia. and i'm sure it wouldn't be cheap or cost effective to send this stuff to the states. so i'm sad to say, i'm out.

well it is if its only carbon fibre with no kevlar. I remember reading one of Carroll Smith's books where he said they went from pure CF in F 1 chassis to CF with kevlar in the weave because CF does not absorb energy very well in a crash. This is because CF it is brittle and has a lower work of fracture than say aramid fibre (kevlar) reinforced polymer or GFRP. This is also the reason why they make bullet proof vests from kevlar and not carbon fibre is because its tough.Originally Posted by steve0suprem0

Carbon fibre has ENORMOUS tensile strength, its incredibly thin, a single layer once glued up, is going to be as thin as paper.
Ill be making these reasonably thick from fibreglass.
When i said an option of carbon fibre, i mean a single outside layer.
Its far too expensive to do the entire thing from it, and it would be very thin, and face it, out cars arent really concerned with a couple of extra kilos anyways
Btw ill get pics up tonight of the originals before we start waxing them up.
The actual mould wont begin for another week or so, wax needs to be applied once a day for about a week and then polished, this gets it into the pores, without this the resin sticks to my originals, and wet wax will cause a horrible surface finish. (hope i can get this wax off after to paint mine :P)
edit, as for Hartge's intelectual property rights, im making some replicas, a very small private run, no matter how hard i try i wont be getting them identical anyways, AND these have been out of production for many years.
I cannot imagine that they would care even if they were told.
