摘要: 本文对含BVID冲击损伤的T300级碳纤维织物层压板的压缩疲劳特性进行了试验研究。依次进行了T300级碳纤维复合材料织物层压板的BVID冲击损伤引入试验、静强度试验、压缩疲劳和剩余强度试验，同时在压–压疲劳试验过程中持续监测了试验件刚度的变化，并间隔性地进行了超声C扫描无损检测，以获取冲击损伤的演化信息。通过本试验研究，获取了含BVID冲击损伤T300级碳纤维复合材料织物层压板的S-N曲线、刚度变化和分层损伤扩展等疲劳特征。
Abstract: In this paper, the compression fatigue test of T300 carbon fiber fabric composite laminates with BVID impact damage was carried out. BVID impact damage introduction test, static strength test, compression fatigue test and residual strength test after fatigue for T300 carbon fiber fabric composite laminates are carried out successively. At the same time, in the process of the compres-sion fatigue test, the change of the stiffness of test specimens is monitored continuously, and the ultrasonic C-scan nondestructive testing is carried out at intervals to obtain the evolution infor-mation of the impact damage. Though the experimental study, the S-N curve, stiffness change and delamination damage propagation of T300 carbon fiber fabric composite laminates with BVID impact damage were obtained.
