【摘要】 对材料为T300/QY8911,铺层为[-45°/90°/45°/0°/-45°/90°/45°/90°]S的层压板进行了横向准静态压痕试验和压-压疲劳试验,用超声波对压痕损伤和不同循环数下的疲劳损伤扩展做了检测,分析了静压痕和疲劳损伤。
【Abstract】 Experimental studies have been carried out to investigate both transverse quasi-static indenting damage and compress/compress fatigue damage propagation of carbon/epoxy composite plate with [-45°/90°/45°/0°/-45°/90°/45°/90°]s stacking configurations.The indenting damage and fatigue damage for different cycle numbers have been measured by means of UltrapactⅡC-scan device. Lastly both damages process were discussed.
