Something carbon fiber to ponder...... - Ducati.ms

......Lamborghini uses a new carbon fiber process to make the new Aventador. Apparently similar to injection molding process, making it ideal for framing and support applications. Apparently Boeing is looking to use it some future planes. How long until we perhaps see it in bikes? I know CF has been used in frames, but this new process allows more dynamic in the frame characteristics and strength.

Just a slow, earth-shaken day........

It's too damn expensive for typical mass production.

Last year, I had to wait 3 months for my local supplier to get a few yards of it in at a decent price.

Wait three months for what ?

Saying "carbon fiber" is like saying "metal". Be specific dude !!!

For unidirectional 9 oz cloth at a decent price.

Now wonders you had problems, uni is uni and cloth is cloth.

do you mean normal vs twill?

Many boat shops cary dry carbon cloth for wet lay-up. good prices too.

Uni cant be raw as it will fall apart, and is usually in pre-peg form or with sizing ready for hot melt.

I would like to see a link of the process you are taliking about in the original post. I would like to see if they are doing this while retaining the ability for Anisotrophy. Otherwise just use metal.

I've been looking for something out there to explain it better, but have come up nil. I know its a joint R&D between Lambo and Boeing. I know it works almost on a principle similar to injection molding but incorporating carbon fiber filaments. CASE in point - the Aventador main chassis carcass is supposed to be one unitary carbon fiber construct. Not sub--section built into one, but ONE whole piece. AND as I understand it may be a process more easily accessible to applying carbon nanotube when that is developed. From what I've heard - traditional pre-preg carbon cloth layout will still be better flat, and widespread areas. But this is supposed to better for structural and more dynamic areas. I'm trying to find more info.

Nay.

UD cloth. It's sewn (stitched) so it won't come apart. Same as when you buy biaxial or triaxial cloth.

I'm not talking about the weave (as in what you mentioned with twill).

Yes, it was for marine application using wet layup (I still pre-impregnate epoxy with a squeegee before layup, but it's not "prepreg") for structural reinforcement.

I have no experience with "prepreg" and have only read about it online.

Are you by any chance talking about forged carbon? Callaway (golf people) invented it, it is also used by high end watch makers (Augemars Piguet maybe?) Short chopped strands of carbon are put into a mold, under high pressure resin is injected. The result is molded parts that can follow much more intricate patterns than regular carbon fiber methods, plus it's cheaper.

Here you go, has links to some videos:

Forged ? LOL.....Sounds like the marketing deparment is at work here.

Subsititute molded for forged and you have nothing more than a molded product using discontinuous fiber in the matrix
