By pressing at very much higher temperatures lower pressures are required as the yield strength of the material is lower.

由于很高温度下材料的屈服强度较低，因此只需较低压力就能挤压。

The SEM fractographs show that the composite interfacial films between the fibre and the matrix are thickened with the increase of the hot-pressing time or pressures.

此外，断口形貌的SEM观察表明，随保温时间的延长或热压压力的提高，复合材料界面层变厚。
