Study on creep behavior of glass fiber reinforced polycarbonate
In this study, tests on creep behavior of glass fiber reinforced polycarbonate were carried out at elevated temperatures. The result showed that creep behavior of GFRPC composites represented good agreement with Arrhenius reciprocation law of time-temperature. The effect of fiber volume fraction on creep behavior was also been studied. Here two shift factors—a modulus shift factor and a time shift factor—were introduced to draw the grand master curve of the creep compliance curves of various fiber contents. It became possible to estimate the creep behavior of GFRPC composites with any fiber contents using the grand master curve of creep compliance master curves and time and modulus shift factors. So it became possible to design materials for creep by reinforcing quantity of fibers to obtain the required objectives.
