摘　　要：针对预应力碳纤维(CFRP)板在加固工程中抗冲击性能较差的问题,对3种不同钢丝掺量的耦合高强钢丝碳纤维(SCFRP)板进行了不同能量的冲击试验,并对受到冲击损伤后的SCFRP板进行了轴向拉伸试验,测得其剩余拉伸承载力。分析了不同SCFRP板之间抗冲击性能的区别,得到了耦合不同钢丝碳纤维板抑制冲击损伤的规律。In order to solve the problem of poor impact resistance of prestressed CFRP plates in strengthening engineering,the impact tests of three kinds of SCFRP plates with different steel wire contents were carried out,and the axial tensile tests were carried out on the damaged SCFRP plates.The residual tensile bearing capacity was got.By analyzing the difference of impact resistance between different SCFRP plates,the law of restraining impact damage by coupling different steel fiber sheets was obtained.
