By rationalizing the mixing of carbon fibers, the coefficient of thermal expansion can be controlled and made zero by design.

In addition to low thermal expansion, light weight and high rigidity, it can be used as a heat dissipation plate to manage heat by using its characteristic of "heat conduction" only in the fiber direction.

Typical parameters: tensile elastic modulus: 800-1000GPa, tensile strength: 3500-4000Mpa, thermal conductivity: 500-800W/m.K, etc.
