Abstract
The effects of the fiber volume fraction of crystallized CFRTP (Carbon Fiber Reinforced Thermoplastic polyimide) on creep behavior were investigated. The bending creep tests for 31wt.% crystallized CFRTPs where fiber volume fractions were 0, 3.7, 7.6 and 15.6% were carried out at constant temperatures from 230 to 265°C. 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 the shape of master curves of CFRTPs mainly depended on the viscoelastic property of matrix resin. The effects of the fiber volume fraction on creep compliance of the master curves are related to the law of mixture. And the relationship between the fiber volume fraction and the shift factors on time axis was linear.
