摘要 含孔复合材料层合板的失效模式与孔的数量和位置等因素有关。为探究含双孔复合材料层合板的失效模式,对不同双孔排布形式下(横孔、竖孔和斜孔)国产T800碳纤维复合材料层合板进行了研究。运用数字图像相关法(DIC)对相机观测到的图片进行处理,得到了三种不同双孔排布情况下复合材料层合板的位移、应变及厚度缩减场,结合拉伸断裂后的损伤形貌分析了对应的失效模式。结果表明:横孔试件的失效模式主要为分层断裂,孔间无开裂现象;其他两种试件的失效模式主要为孔边断裂错位,孔间开裂现象严重。

Abstract: The failure modes of notched composite laminates are related to the number and position of holes. Domestic T800 carbon fiber composite la-minates with different double holes arrangement (transverse holes, vertical holes and oblique holes) were studied to explore the failure modes of double-notched composite laminates. The displacement, strain and thickness reduction field of the composite laminates under three different double-hole arrangements were obtained from processed images of the camera through digital image correlation method (DIC). Combined with the above three results, the corresponding failure modes were analyzed based on the damaged morphology after tensile fracture. The results show that the main failure mode of transverse hole specimens is layered fracture without cracks between holes; the main failure modes of the other two specimens are the hole edge fracture dislocation with serious cracks between holes.
Key words:  domestic T800 carbon fiber    different hole arrangement    digital image correlation    failure mode
