摘要
使用自动铺带工艺制得胶接的碳纤维复合材料层压板试验件,通过轴向拉伸测试,测得了整个试验件的载荷-位移曲线和检测点附近的应变-载荷曲线。试验结果表明,在拉伸载荷作用下试件发生层间剪切破坏,由于胶层的剪切强度高于层合板的层间剪切强度,破坏并没有发生在胶接面内,而是发生在胶层以外的层合板的层间。建立了相应的有限元模型,模拟结果和试验结果的一致说明了有限元模型的合理性。
Bonded carbon fiber composite laminates samples were produced with automated tape-laying process.Load-displacement curves of whole composite samples under axial tensile load were obtained,and strain-load curves were available through the strain flowers around monitoring points.The results shows that coupon was damaged with interlaminate shearing fracture under the tensile load,and the damage mainly locates in the interlaminate layer rather than in the bonded area because shear strength of bonded layer is higher than that of interlaminate of composite.One finite element analysis model is established and verified with the high agreement between simulated and experimental results.
