Carbon/carbon composite materials have become a new generation of brake materials to replace metal based composite materials due to their unique mechanical, thermal and friction and wear properties.
Its main features are as follows:
(1) The density of the material is as low as 1.5g/cm3, which can significantly reduce the structural mass of the brake disc;
(2) The material has excellent wear resistance and the brake disc has a long service life, which is more than twice that of metal matrix composite materials;
(3) Stable dynamic friction factor, excellent anti-sticking and anti-adhesion properties;
(4) Simplify the brake disc design and do not require additional friction linings, connectors, brake skeletons, etc;
(5) Small thermal expansion coefficient, high specific heat capacity (twice that of iron), and high thermal conductivity;
(6) Carbon/carbon brake disc has high working temperature and heat resistance up to 2700℃.
