It is known that a mechanical property will change because a crystalline polymer adjusts a crystal region. It is important to grasp about the viscoelastic property for a long-term reliability. Then, this research examined the creep behavior using the polyamide resin and glass fiber reinforced polyamide which the various degrees of crystallization adjusted by the three point bending creep test. As a result, crystallinity increases with heat treatment temperature, and it develop that crystallinity can be artificially adjusted. Then bending creep behavior was suppressed with crystallinity increasing, and this tendency was significant at longer test time. And superposion low of Arrhenius type of time-temperature formed, and master curve of creep compliance curves could be made.
