An important thing of FRPs to use in structural member is to understand the visco-elastic behavior of them. In this study, creep behavior of glass fiber reinforced Polycarbonate (GFRPC) was researched. Before the creep test, GFRPCs were heated for various times at test temperature for aging treatment to research the effect of physical aging. The result shows that creep behavior of GFRPCs with various aging treatment could be able to make master curves of creep compliance on each aging conditions. And time-temperature shift factors with various aging conditions represented good agreement to time-temperature superposition principle of Arrhenius type plotting. To research the effect of physical aging quantitatively, it was compared with the master curves of various aging conditions. Therefore, the effect that the physical aging exerted on the visco-elasticity behavior was able to be understood including the existence of the fiber content.
