Recycling of fiber-reinforced composites and direct structural composite recycling concept (2014, background): “The processing temperature is usually between 400 C and 1000 C, depending on the types of composites and reinforcement materials.(22) This temperature is high enough to completely degrade even the CFs.”
Recycling carbon fibre reinforced polymers for structural applications: technology review and market outlook. (2011, background): “During pyrolysis, the CFRP is heated up to 450 ◦C to 700 ◦C in the (nearly) absence of oxygen; the polymeric matrix is volatilised into lower–weight molecules, while the CFs remain inert and are eventually recovered (Marsh 2008, Meyer et al. 2009).”
