Abstract
The fatigue reliability of recycled advanced fiber reinforced thermo plastic (FRTP) resin was examined. In particular, the effects of the mesoscopic factor on the fatigue crack propagation (FCP) orientation and length of resin matrix on the FCP property of recycled FRTP is remarkably different among PEEK (Poly-Ether-Ether-Ketone). PPS (Poly-Phenylen-Sulfide) and PA·MXD6 (Poly-Amide-MXD6). (2) From fractography using SEM, it was found that the triple structure of recycled materials was different among these resin matrixes. Thus, it could be interpreted that the influence of the recycling process for each resin on the FCP property was caused by the different fiber orientation and length. (3) It was found that controlling the mesoscopic structure of the recycling process would improve the decline in the FCP property of recycled materials.
