• The effects of the fiber volume fraction of CFRTP (Carbon Fiber Reinforced Thermoplastic polyimide) on creep behavior were investigated. The bending creep tests for resin and CFRTPs where fiber volume fractions were 3.7, 7.6 and 15.6% were carried out at constant temperatures from 190 to 240℃. For all materials, master curves of creep compliance could be drawn and the reciprocation law of time and temperature of Arrhenius type was applied. With shift not only on the time axis but also on the compliance axis, these 4 master curves were found to correspond to each other. Hence it was concluded that master curves of CFRTPs mainly depended on the viscoelastic property of resin. The effects of the fiber volume fraction on the shift factor on the compliance axis when adjusting master curves of CFRTPs to the master curve of resin is related to the law of mixture.
