In this study, the construction of life design method which considered loaded condition by machine using fiber reinforced engineering plastic (FRTP) was examined Especially, the demonstrative research was carried out on the effect of load fluctuation on fatigue life at elevated temperature environment above Tg from mesosocpic viewpoint. The main results were as follows; (1) It was proven that there was the load waveform effect in fatigue characteristics of this material. (2) From the fractography by using SEM, it was proven that fatigue fracture surface was influenced by difference of shape of applied stress. (3) That the load waveform gave the change for the deformation time for the stress clarified. This fact affected the creep property of this material, and the difference seemed to occur in the fatigue life.
