Kevlar Fibre??

Hi all. I was wondering if that's Kevlar Fibre here:

I start that kit just today. I almost finish the rear dif-llinks-brakes zone, and, i have seen that, and say, "Why not?". So, I applied the decal on the transmision tree. Maybe tomorrow I'll hook up some progress pics... (Anybody know some site to make that, beside www.photobucket.com?) But now I only want to know that...

GREETINGS

Which part are you referring to?

Whichever, I don't see any kevlar fibre or any other type of fibre in there.

If you're talking about the drive shaft, I don't think so.

Then... What the hell is that yellow/grey/black thing?

The drive shaft....

Or do you mean material?

Either an lightweight alloy or steel like 4130. It looks like it has some sort of tectyl coating on it to me.

I mean the material of the drive shaft...

It's carbon fibre. Here is the link with an explanation. Look for the driveshaft pic and it explains it all. http://www.sportcompactcarweb.com/features/0505_scc_skyline/

Interesting reading, thanks for posting the link.

Would love to know what process they use to produce the driveshaft.

At least I was right it wasn't kevlar :icon16:

carbon composite?

Ha ha, I KNEW it!!! LOL
I knew about composites drive shafts from som e years. But in the pic, it looks other thing...

THANKS A LOT PEOPLE.

One good friend of mine is a New Materials Engeegner (Trento's Univ.) and work on C.F. applications. For his degree he design and develop a machine to produce those kind: basically is like a weawing loom but work radially, so it's the way to produce CF pipes. In the factory when he work they done a lot of stuff, from fishing equipment to bike exaust to structural item, often these're sandwich of kinds materials, like stainless core under some CF, Kewlar or alu mesh layers.

Strange: in bikes exaust they use an iron mesh under CF to allow rivets applications (terminals) it's weight is at least is similar than an alu exaust, the look not obviously

Definitively those color seem a protection stuff over carbon

I know how they produce C/F tubes and the like, I am referring to how the place enough strength in the tube to withstand the radial moments experienced under accelerations, perhaps they use a honeycomb inside the shaft similar to what Trek does with its frames.

I think so freakray. I don't think that composite material is capable of resist the stress from the acceleration, and, with around 500 hp, too difficult...

GREETINGS

I think I'm in wrong abt protection over carbon shaft:
hve a look here: pattern seem like the wwe texture

http://www.pstds.com/

and abt construction, Ray, seem like i'm in right: forged 7075 shaft bonded into CF tubing
http://www.designnews.com/article/CA336597.html

or like here, with 2 different composite layers: inner CF>alloy shaft>outer CF

or like here, where alu and CF are 1 only solid material, with alu oriented fiber on CF

so, maybe someone use honeycomb inside :)
