Description
Summary:The creep behavior of long glass fiber reinforced thermoplastic composite was investigated under different constant tensile stress and temperature. From the time‐dependent strain curve, the critical creeping time was defined as the transition point from steady to unsteady deformation and measured correspondingly. A statistical Weibull distribution function was adopted to describe the critical creeping time distribution at each stress level. A power law was employed to analyze the behavior of steady deformation stage of strain during loading. The relation between the critical creeping time and the parameter (m) of the power law is analyzed and discussed.
