本文论述了用热压法成型热塑性树脂PEEK和碳织物或玻璃织物复合材料的工艺研究,表明复合材料的质量与温度、压力和时间等条件有关。通过流变性能试验,计算表观流动活化能和在同样剪速下熔体相差40℃的粘度,考察了PEEK对温度的依存性。用超声C-扫描的结果表征工艺参数的变化,表明该方法有很好的选择性,较其他方法敏感。 In this paper, the research on the process of molding PEEK and carbon fabric or glass fabric composites by hot pressing is discussed. The results show that the quality of the composites is related to the conditions of temperature, pressure and time. Through the rheological property test, the activation energy of apparent flow and the viscosity of the melt at the same shear rate of 40 ℃ were calculated. The dependence of PEEK on the temperature was investigated. The results of ultrasonic C-scan characterization of the process parameters show that the method has good selectivity, which is more sensitive than other methods.
