New processes promise lower cost carbon fiber

02/08/2016

Teijin Group company Toho Tenax has developed two new processes for the production of carbon fiber that when commercialized should slash the amount of energy used in its manufacture

The company has, in a claimed world first, utilized microwave energy to carbonize the polyacrylonitrile (PAN) fiber precursor under atmospheric pressure and realize a carbon fiber with a tensile modulus of 240 GPa or greater and rupture elongation of 1.5% or greater, both equivalent to levels found in industrial products.
