摘要
选用T300/4211环氧基碳纤维增强复合材料,应用半经验数学模型,结合短期不同气候区的自然老化数据和人工加速老化数据,预测其长期使用下(15年和30年)力学性能的变化,估算复合材料结构的工作寿命,为复合材料飞机构件的性能评定提供参考依据。
his article presents application of a mathematical prediction model to T300/4211 composites. Com-bining results of natural aging experiments in various climatic conditions and results of accelerated aging ex-periments,the degration in mechanical properties of material under long term service(15 years and 30 years)is predicted,and life-time of structure is estimated.The result would be basis in evaluating the reli-ability for CFRP parts of aircraft.
