Mesophase pitch-based carbon fiber (MPCF) is processed by a series of
processes such as spinning, oxidation, carbonization, and graphitization,
using mesophase pitch, a material that is easy to graphitize, as a
precursor. The lamellar macromolecules composed of carbon elements are
aligned along the fiber axis, and the fibers are in a highly graphitized
state, showing excellent macroscopic properties such as high modulus, high
thermal conductivity, electrical conductivity, electromagnetic shielding,
damping, and low thermal expansion coefficient. The modulus can reach more
than 900GPa, and the thermal conductivity can reach 1200w/m﹒k or more.
