摘要：In this article, continuous glass fiber and basalt fiber-reinforced polyphenylene sulfide prepreg tapes were prepared through powder impregnation and then woven into fabrics for laminate molding to manufacture laminates. After that short-term flexural creep behaviors at various temperatures and stresses were investigated using a dynamic mechanical thermal analyzer (DMTA). The result showed that creep strain increased with increasing temperature and applied stress. When fiber weight content reached 50%, the creep resistance was significantly improved in comparison with 30% and 40%, especially at high temperature. Then the DMTA data were used to predict long-term creep behavior by time-temperature superposition (TTS) and Findley's power law model. It was found that there was a discrepancy between the two predictions. By comparison, TTS prediction based on all test temperatures was more accurate. Simultaneously, experiments of long-term creep behavior were also carried out to assess TTS prediction. The result showed that long-term creep behavior predicted from TTS could be accepted.
