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:
High thermal conductivity printed circuit board (PCB)
Power component
PV inverter (IGBT)
Automotive power substrate
Mesophase pitch-based carbon fiber integrates many characteristics such as light weight, high modulus, high strength, high thermal conductivity, electrical conductivity, electromagnetic shielding, low thermal expansion coefficient, and strong process designability, and will become a key material in many fields.
