Abstract
It was well known that crystallization on the thermoplastic resin resisted the progress of viscoelastic deformation But there are a few reports for the effect of crystallization on viscoelastic deformation on polymers and also few report on fiber reinforced plastics(FRP). In this report, for CFRP of Polyimide, the effects of not only the fiber volume fraction but also crystallization on bending creep behavior were researched because creep behavior in viscoelasticity is the most important design factor. The time-temperature dependence of creep behavior on some kind of fiber volume fraction and the resistance of crystallization on creep were confirmed.
