Carbon is used in the manufacturing of tree Gaston Mercier ans stirrups Bi-relax

Carbon fiber is made up of extremely thin fibers, about five to ten microns in diameter, and is composed mainly of carbon atoms.
These are agglomerated in microscopic crystals that are aligned more or less parallel to the long axis of the fiber. The alignment of the crystals makes the fiber extremely resistant to its size. Several thousand carbon fibers are wound together to form a yarn, which can be used as is or woven.

This material is characterized by its low density (1.7 to 1.9), its high resistance to traction and compression, its flexibility, its good electrical and thermal conductivity, its temperature resistance and its chemical inertness (except for oxidation).

Its main use is to serve as reinforcement in composite materials, which allows to obtain parts with good mechanical properties while being significantly lighter than metal parts.
