Carbon fiber isn't "special" or "magical". On its own, it's pretty useless. What makes it special is when it's embedded in a resinous matrix to form a composite material - the matrix resists compressive forces, the fibers resist tensile forces, giving you "the best of both worlds".

 

Bone is *already* a composite material, a mix of the mineral hydroxyapatite (for compressive strength) and collagen fibers (for tensile strength), created at a molecular level and constantly adapting and repairing.

 

A carbon-fiber bone would have at best modest improvements, certainly nothing truly awe-inspiring.

So ... which would be more "natural" - a carbon-fibered SKIN or a carbon-fibered BONE? And, what would be the likihood of BOTH occuring in one animal?
