High strength grade (HT): the strength reaches 3.5GPa.
Main uses of carbon fiber
A special fiber made of carbon. It has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance. It is fibrous and soft, and can be processed into various fabrics. Because its graphite microcrystal structure is preferentially oriented along the fiber axis, it has high strength and modulus along the fiber axis. Carbon fiber has low density, so its specific strength and specific modulus are high.
The main purpose of carbon fiber is to be used as a reinforcing material, compounded with resin, metal, ceramics and carbon to make advanced composite materials. Carbon fiber reinforced epoxy resin composites have the highest specific strength and modulus among existing engineering materials.
