The thermoplastic Poly-ether-ether-ketone (PEEK) is a kind of heat-resisted plastics, and recently come into using with CF/PEEK (Carbon Fiber Reinforced PEEK) in high temperature. In this study, purposes were to mechanical properties by the three point bending creep test. As a result, the longer heating treatment time was, the more crystallinity was increased, and when they were crystallized at 300℃. Then bending creep behavior was suppressed with crystallinity increasing, and this tendency was significant at longer test time. And Arrhenius reciprocation of time-temperature formed, and master curve could be made.
