摘　　要：在800℃下对2. 5D石英纤维/酚醛复合材料进行不同时间的热处理,最长热处理时间为20 min,之后测试其残余力学性能,并利用Mouritz-Mathys模型计算热处理后的理论值。结果表明,随着热处理时间的延长,复合材料热处理后的力学性能急剧下降。在所有的测试中,测量和理论的残余机械性能之间的一致性在15%以内。使用该模型可以快速地获得复合材料热处理后的力学性能与时间的变化规律。In this paper,2.5D quartz fiber/phenolic composites were thermally treated at 800℃for different time.The longest thermal treatment time was 20 min.Then the residual mechanical properties were tested.Mouritz-Mathys model was used to calculate the theoretical values after thermal treatment.The results show that the mechanical properties of the composites decrease sharply with the increase of the thermal treatment time.In all tests,the consistency between measurement and theoretical residual mechanical properties was less than 15%.Using this model,the variation of mechanical properties and time after thermal treatment can be obtained quickly.
