本研究主要通过45°纤维束拉伸（45FBT）试验评估碳纤维/环氧树脂界面抗剪强度。制备了三种不同碳纤维/环氧树脂体系的45FBT样品并进行了测试。建立了基于广义单元法（GMC）的多尺度模型，模拟了拉伸损伤过程，分析了界面应力状态。计算了45FBT试样的界面抗剪强度。将45FBT试验与横向纤维束拉伸（TFBT）试验进行比较。最后讨论了45FBT试验的适用性。
This work concentrates on the assessment of carbon fiber/epoxy interfacial shear strength by 45° fiber bundle tensile (45FBT) test. The 45FBT samples for three different carbon fiber/epoxy systems were prepared and tested. The multiscale model based on the generalized methods of cells (GMC) was established to simulate the tensile damage process and analyze the interfacial stress state. The interfacial shear strength in 45FBT specimen was calculated. The 45FBT test was compared with the transverse fiber bundle tensile (TFBT) test. The applicability of the 45FBT test was finally discussed.
