纤维增强高填充聚苯硫醚复合材料及其制备方法
技术领域
本发明属于复合材料技术领域，具体涉及一种纤维增强高填充聚苯硫醚复合材料及其制备方法。
背景技术
聚苯硫醚全称为聚苯基硫醚，是分子主链中带有苯硫基的热塑性树脂。具有优良的耐高温，耐腐蚀、耐辐射、阻燃性、均衡的物理机械性能、极好的尺寸稳定性和优异的电性能，热变形温度(1.8MPa，未退火，3.20mm)为93.0℃，拉伸模量为2500MPa，弯曲模量为3300MPa，悬壁梁缺口冲击强度(23℃)为29J/m。因此在汽车制造、电子电气、化工、仪器仪表和航天工业等方面具有广泛的应用。
但由于PPS主链上大量的苯环增加了高分子链的刚性，其韧性变差，因而在应用中受到了一定的限制。现有技术中，通常采用纤维材料改善其韧性，但添加纤维后，复合材料的密度增大、流动性较差，表面粗糙度增加，因而损坏PPS其他优越的性能，如大幅度降低PPS材料的热变形温度、机械强度等。
