【摘要】 以玻璃纤维增强新型可固化环氧热塑性材料－环氧封端聚芳醚酮（Ｅ－ＰＥＫ）体系为研究对象，将温度和反应程度对Ｅ－ＰＥＫ热物理性能（包括比热、密度和导热系数）的影响引入到其加工过程的模拟计算中，在模拟的基础上，确定了玻璃纤维增强Ｅ－ＰＥＫ的加工参数，并依此参数制备了复合材料．所得复合材料的性能表明了这种影响在加工过程中是确实存在的，而其影响也是必须考虑的．考虑了这种影响，模拟得到的加工参数的范围变小，模拟的结果更为准确、可靠．更多还原

【Abstract】 The influence of the variation of temperature and the extent of cure on the thermal physical properties is introduced in the processing simulation of epoxy terminated poly (phenylene ether ketone)(E-PEK)composite.The processing parameters of glass fiber reinforced E-PEK were determined through the process simulation .The processing window became narrower when considering the influence of the variation of the thermal physical properties of E-PEK .The validity of the simulation results was evaluated by the characterization of the mechanical properties of glass fiber reinforced E-PEK.It is proved that it is necessary to consider the variation of thermal physical properties and then the simulation is more accurate.更多还原
