Effect of Crystallization on Creep Behavior of Glass Fiber Reinforced Polyacetal

摘要: Thermoplastic Polyoxymethylene (Polyacetal / POM) is one of the engineering plastics. It very important for POM and its FRP to grasp accurately viscoelastic behavior. Furthermore, a crystal- line polymer with high crystallinity. Therefore, it necessary consider effect crystallization. The pur- pose this study was make clear crystallization on bending creep behavior glass fiber reinforced (GFRPOM). considered that there are two factors One linity which calculated by ratio crystal amorphous part, other grain size represents interior morphology. test performed using materials adjusted crys- tallinity. As result, these conformed Arrhenius type time-temperature superposition principle, crystallinity had time retardation effect. made shape master curves different every size. makes dif- ferent Only considering same size, able estimate long term
