What two pieces are you talking about? Carbon fiber bends easily... it's a cloth.

What do you mean "we make our own carbon fiber"? do you mean that you make parts from carbon fiber, or you are with a company that weaves the fibers?

 

im talking about if you look at the cobb piping you can see a seam in it...like its bonded together somehow. how are they connected? what do they use?

i work for a company that builds all types of parts for aircraft. they make their own carbon fiber for the parts. the bad part is its not like i can get my hands on it to do anything with cars...lol

 

looks like they are lined and wrapped...

but ive never seen a CF pipe.

id pass anyway i can make a nice pipe out of stainless or aluminum and weld it my self to save money. CF is getting to be outrageous these days

 

Looks Awesome!!!

 

I'm willing to bet that the mold they have is based off of a metal pipe that they used as a plug. This is why there seems to be a weld seem in the carbon fiber.

This would be good to make 1 or 2 parts for a show like SEMA, but for a mass produced item, the mold should be a CNC milled alluminum female. With this, you could not only make the pipe, but you could also have it change diameters, make very tight bends, and alot of other cool stuff.

Upon closer inspection, it looks like there is an outer and an inner layer of carbon fiber with something inbetween. perhaps this is a foam or honeycomb.

I would love to get my hands on one of these to see the construction.

Carbon fiber is not really expensive or that rare, but because it's so "bling bling" people who make things from carbon fiber get a premium for it.

 

OK, so I spoke to Justin with Cobb tuning about these pipes. He along with Christian and Billy made these.

These pipes were a test for the market to see how much of a hit they were :-)

Turns out that what they did was make a pipe out of plastic on their rapid prototyping machine, they then wrapped 2 carbon fiber sleeves around the plastic, did a wet lay up and used large heat shrink 6"s at a time to compress the part and squeeze out the resin.

What you see as a "weld seem" is where they had epoxied two of these plastic pipes together to get the shape.

They were supposed to break the plastic out of the carbon fiber before the show, but ran out of time, so what you see on the inside is the plastic from the rapid prototyping machine.

 

Close. The piping was actually gypsum, not plastic. The seams are actually where the short pieces of heat shrink ended. So the seams are epoxy from not having a smooth outer mold. The pipes were sanded smooth after gluing them them together.

 

Thanks, I realized I explained it wrong after I wrote it :-)

 

Thats interesting.Looks like it will cost an arm and a leg.

 

i agreed. it looks cool, but i dont think CF will transfer heat as well as metal (aluminum in particular)... and thats the whole point of the IC...

EDIT: nvm... i didnt realize the core was aluminum still. cool part though.
