摘　　要：针对聚合物基复合材料吸湿平衡后在高温环境条件下具有湿气损失的特点,开展了T300级碳纤维环氧聚合物基复合材料经过吸湿处理达到平衡后,在不同高温环境条件下的湿气损失特性研究,初步探索了碳纤维复合材料在多种高温条件下湿气的损失规律,研究结果表明聚合物基复合材料试验件在低于71℃温度环境条件试验时,保温时间在15分钟内仍能保持吸湿平衡,而对于82℃和120℃温度环境应尽量控制在10分钟和5分钟以内。In view of the moisture loss of polymer matrix composite under high temperature environment after moisture equilibrium, the moisture loss of T300 carbon fiber epoxy resin matrix composite under various high temperature environments after moisture equilibrium is studied, and the moisture loss law of carbon fiber composite under various high temperature conditions is preliminarily explored. The results show that the moisture absorption balance can be maintained within 15 minutes when the temperature of polymer matrix composites is lower than 71˚C, while the temperature is 82˚C and 120˚C, it should be controlled within 10 minutes and 5 minutes.
