PAN Chopped Carbon Fiber
Chopped carbon fibers are obtained by using special cutting machine, which cuts continuous PAN based carbon fibers into several millimeters length carbon fiber and carbon fiber powder is obtained by grinder. Chopped carbon fiber can be composited with resin, plastics, cement, rubber in order to increase the strength and wear-resistance . The chopped carbon fibers also can be used as the conductive additive of lead sealing in Pb-acid cell. The utilization ratio of the positive electrode can be improved from 18.3% to 42.5% after adding 1% chopped carbon fiber into the cell.
