About pitch based carbon fiber
Application of composite with carbon fiber is extended in many sectors from aerospace to industry. The properties and application are introduced in this content.
Unique properties of pitch based carbon fiber
Pitch based carbon fibers are characterized by wide variety of tensile modulus from low modulus (55GPa) to ultra high modulus (900GPa). High modulus is very attractive for applications where high stiffness and light weight are required. Apart from high modulus and stiffness, high thermal conductivity is unique character of pitch based carbon fiber、GRANOC. Carbon fiber having 900 GPa in modulus and 900 w/m K in thermal conductivity can be achieved only from pitch base. The requirement of thermal management is increased in high-powered electronics system and smaller electronics components.
