1. About
Mesophase Pitch-based Carbon Fibers
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.
2. Mesophase Pitch-based Carbon Fiber (MPCF) Metal Matrix Composites
Metal matrix composite material is a new material that is composed of metal as matrix and inorganic non-metallic fibers, whiskers, particles or nanoparticles as reinforcements. Generally, it can be divided into aluminum-based, magnesium-based, titanium-based, copper-based and iron-based composite materials. MPCF metal matrix composites can solve the heat dissipation problems of high-power equipment and high heat flow accumulation parts that are difficult to deal with by conventional materials. Appears as:
Reduce the weight of parts;
The thermal conductivity in the dominant direction reaches 700W/m﹒K or above;
MPCF has a low thermal expansion coefficient and is combined with the metal matrix, and the overall thermal expansion coefficient is highly designable;
Retain the craftsmanship of the original metal parts and their compatibility with the overall equipment.
