Manufacture of Pitch-based carbon fibers--CFCCARBON LTD

Mesophase pitch-based carbon fibers are an attractive precursor candidate for carbon fibers because of the high availability of low-cost raw pitch. There are several reasons why the mesophase pitch process should produce a lower cost, high-performance fiber. First, the starting material (petroleum or coat-tar pitch) costs 40-50 percent less than the monomers used to form PAN. Second, because
