摘　　要：创新性将碳纤维增强复合材料(Carbon Fiber Reinforced Polymer,CFRP)与304不锈钢(304stainless steel)复合形成碳纤维增强钢层板(Carbon Fiber Stainless Steel Laminate,CFSSL),通过对不同钢板厚度CFSSL低速冲击试验,研究其冲击特性;基于试验结果,利用有限元软件ABAQUS对不同锤头直径低速冲击作用下的动力特性进行了数值模拟。试验与数值计算结果表明:CFSSL较CFRP层合板有更大的能量耗散和更好的抗冲击性能,且钢板厚度与CFSSL峰值冲击荷载呈正相关关系;试件破坏模式对其能量吸收有较大影响;锤头直径变化影响峰值荷载、能量吸收、最大变形和残余变形等动力特性指标。Carbon fiber reinforced polymer(CFRP)and 304stainless steel(304stainless steel)are innovatively compounded to form carbon fiber reinforced steel laminate(CFSSL).The impact characteristics of CFSSL with different steel plate thicknesses are studied through low-speed impact tests;Based on the test results,the finite element software ABAQUS was used to simulate the dynamic characteristics of different hammer diameters under low speed impact.The experimental and numerical results show that CFSSL has greater energy dissipation and better impact resistance than CFRP laminates,and the thickness of steel plate is positively related to the peak impact load of CFSSL.The failure mode of the specimen has a great influence on its energy absorption;The variation of hammer diameter affects the dynamic characteristic indexes such as peak load,energy absorption,maximum deformation and residual deformation.
