Abstract
A pyrolysis method was applied for recycling of carbon fiber in CFRP. From the results of thermo-gra-vimetry and differential thermal analysis, carbon fiber in CFRP began to be oxidized after almost all the resin in CFRP disappeared by pyrolysis. Consequently, it was possible to recover carbon fiber with an almost 100% yield as a residue by pyrolyzing CFRP under appropriate conditions. The recovered carbon fiber has good mechanical properties and a surface condition as those of the original, enough to be used again.
