It is a carbon fiber laminate. The cloth is a 4 or possibly 5 harness satin weave and I'd guess the tow size at 3K. It would be about 0.015 in thick per ply. It looks like it was made on a mold of some kind, but whether the team made the mold or the part was purchased is difficult to tell at this time. A look at the back side would give better indications of the technique used.

Actually he did a pretty good job of bringing out the fibers in the picture and the finish shows a good job of molding, whoever did it. Carbon composite parts can be difficult to photograph for detail. When was the last time YOU tried to take a picture of black on black?

What I can't tell by looking is which carbon fiber was used. Carbon fibers come in many grades and different manufacturers have different chemistries in their precursors, giving different results. Unfortunately all grades look pretty much alike until you get them in a structure or on a test machine. Guessing from the weave and financial considerations, I'd say it's AS4, T300 or a commercial grade fiber and not the more expensive IM7 or similar high modulus fiber.

Any other silly questions?
