以含二氮杂萘酮联苯共聚芳醚砜(PPBES)为树脂基体,连续碳纤维T700-12K为增强材料,采用溶液浸渍和模压成型的方法制备出单向复合材料.通过对复合材料样条进行三点弯曲以及短梁剪切力学性能测试,考察了复合材料纤维体积分数、模压成型温度、成型压力及保压时间对复合材料弯曲强度、模量及层间剪切强度的影响.分别测试了复合材料在干态及湿态下的高温力学性能的变化规律.结果表明,当复合材料纤维体积分数为63％,模压成型温度为350℃,成型压力为4 MPa,保压时间为20 min时,复合材料的力学性能最佳.动态热机械性能测试结果表明复合材料在230℃之前,储能模量保持稳定.而水煮48 h后复合材料的吸水率为0.3％.
