Abstract:In order to obtain fundamental knowledge on the thermal recycling of FRP, the TG and DTA of FRP under air flow were measured. The influences of types of fiber and matrix resin, resin fraction and additive on the thermal degradation and combustion processes were examined for GFRP and CFRP. The following results were obtained.
(1) The decomposition and ignition temperatures of GFRP made from UP resin were lower than those of the FRP made from Ep resin. (2) The ignition temperature of FRP was lower than that of matrix resin. (3) Carbon fiber in a CFRP burned at lower temperature than the non-composite carbon fiber itself. (4) The powder form samples of resin and FRP decomposed and burned at lower temperature than the block form samples. (5) The addition of calcium carbonate did not influence the thermal degradation and combustion processes of GFRP.
