Open hole tension and compression behavior of 3D braided composites

摘要

Abstract >The damage tolerant behavior of 3D braided composites is evaluated in terms of the open‐hole notch strength test under tensile and compressive loading. The influence of fiber architecture is evaluated by comparing 3D braid with and without axial yarns as well as laminated composites based on ASTM quasi‐static tension and compression testing standard. The results show that the notched and un‐notched properties of the two types of 3D braided composites are similar under tension and compression loading. Comparing to laminates, both types of 3D braided composites demonstrated superior notch insensitivity than laminated composites. For the failure behavior of the 3D braided composites, under tension loading, crack of both notched specimens tends to propagate along the notch and finally render the specimen to failure. Clear cracks usually presented on the samples without axial yarns, while not for the specimens with axial yarn. Under compression loading, the two types of 3D braided composite are also macroscopically similar, showing transverse fracture. The modified Fabric Geometry Model is used to predict the tensile properties of 3D braided composite. The predicted and experimental results are shown to be in good agreement. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation

>在拉伸和压缩载荷下的开孔凹口强度试验方面评估了3D编织复合材料的损坏行为。通过基于ASTM准静态张力和压缩测试标准将3D编织物与轴向纱线的3D编织物进行比较，通过比较3D编织物以及层叠复合材料来评估光纤架构的影响。结果表明，两种类型3D编织复合材料的缺口和未缺陷的性质在张力和压缩负载下类似。与层压板相比，两种类型的3D编织复合材料显示出比层压复合材料的优异的凹口不敏感。对于3D编织复合材料的故障行为，在张力载荷下，两个缺口样本的裂缝倾向于沿凹口传播，最终将样本使样品变为失败。通常在没有轴向纱线的样品上呈现的透明裂缝，同时不适用于轴向纱线的样品。在压缩负载下，两种类型的3D编织复合材料也是宏观相似的，显示横向骨折。改进的织物几何模型用于预测3D编织复合材料的拉伸性能。预测和实验结果显示良好一致。</
