Abstract
PEEK is well known that it is the best heat resistance material in the engineering plastics. This material is usually used in the industrial field of aero space and aircraft field. Further more, CF/PEEK shows not only the good static mechanical properties but also the higher heat resistance rather than PEEK. Even though there are few report and data for the heat resistance without the data obtained by the standard test such as DTUL. The purpose in this research is to make clear the creep phenomenon of CF/PEEK and to discuss the application of reciprocation law on it between temperature and time using the results obtained by three point creep test. And the effect of crystallization of resin matrix on creep phenomenon was discussed.
