摘要: 利用4D X射线CT原位拉伸试验和深度学习技术，表征拉伸作用下准各向同性铺层缎纹C/SiC的损伤失效过程，揭示(0°/90°)铺层拉伸和(±45°)铺层剪切耦合作用的材料损伤演化机理。基于深度学习图像分割方法对载荷作用下基体裂纹、分层等损伤进行智能识别，提取损伤特征开展定量分析，结合断口形貌探究损伤与失效机理。研究发现：基体裂纹中±45°斜裂纹占主要部分，演化过程为初期裂纹不断扩展；横向裂纹虽然少于斜裂纹，但其长度和裂纹张开位移发展快；基体裂纹沿层间界面偏转诱发分层。(0°/90°)缎纹铺层组织点区90°纤维束出现横向开裂，浮长区伴随纤维束弯曲；组织点区0°纤维束发生断裂，浮长区伴随纤维束纵向劈裂。(±45°)缎纹铺层发生−45°(或+45°)纤维束斜向劈裂和相对错动，同层+45°(或−45°)纤维束则发生纤维束断裂，伴随纤维桥连弯曲。Abstract: 4D X-ray CT in-situ tensile testing, along with deep learning technology, was used to characterize the damage and failure process of quasi-isotropic lay-up satin C/SiC composites under tensile loading, and to reveal the damage evolution mechanism under the coupled action of (0°/90°) lay-up tension and (±45°) lay-up shear. Using the deep learning image segmentation method, damages were extracted for quantitative analysis based on intelligent detection of matrix cracks, delamination of the material under loading. Furthermore, damage and failure mechanisms were investigated by examining the fracture morphology. It is found that ±45° oblique cracks account for the major part of matrix cracks. Oblique cracks were mainly induced by small cracks at the initial loading stage. Although transverse cracks were less than oblique ones, their lengths and crack opening distance developed rapidly. Delamination was induced by the deflection of matrix cracks along the interfaces between adjacent layers. For a (0°/90°) satin lay-up, transverse split took place in the tissue point region of 90° fibre tows, and accompanied by bending in the floating length region of 90° fibre tows. Fractures occurred in the tissue point region of 0° fibre tows, and accompanied by longitudinal split in the floating length region of 0° tows. For a (±45°) satin lay-up, oblique split and relatively sliding occurred in −45° (or +45°) tows. While fractures accompanied by fibre tow bridging and bending took place in the +45° (or −45°) tows of the same lay-up.
