玻纤表面处理对于玻纤增强PET复合材料断裂韧性的影响

EFFECT OF SURFACE-TREATING OF GLASS FIBER ON THE GF/PET COMPOSITES FRACTURE TOUGHNESS

本文以三组分别经脱蜡处理、涂层处理及未经任何处理的玻纤为增强纤维，ＰＥＴ为基体纤维，采用混纤纱浸渍技术，制备连续玻纤增强混纤纱复合材料单向板。通过对所制备材料力学性能的对比，研究了玻纤表面处理对玻纤增强ＰＥＴ复合材料断裂韧性的影响。

In this paper we used three sorts of different surface-treated glass fiber as reinforced fiber and PET as matrix fiber to get GF/PET commingled yarns.Through comparing properties of the composites made by these commingled yarns,we studied the effect of surface-treating glass fiber on the GF/PET composites fracture toughness.
