In this study, the purposes were to discuss about bending creep behavior on polyamide resin and glass fiber reinforced polyamide. First, to search the thermal characteristic, DSC test was performed. Next, to control GFRPA's crystallinity, it proposed a new heat-treatment method. Adjusting the crystallinity by the heat-treatment at 250℃ and different time became possible. Third, to search the effect of their crystallinity on bending creep behavior by 3 point bending creep test. As a result, the longer heating treatment time was, the more crystallinity was increased. Increasing crystallinity, creep deformation of these materials was reduced. Last, the effect of their fiber reinforcement on bending creep behavior was examined. As a result, the creep deformation and the progress of the transformation were controlled by fiber reinforcement.
