聚氨酯泡沫填充的碳纤维增强复合材料锥管吸能性能数值模拟及试验验证
Numerical Simulation and Experimental Verification of Energy Absorption Performance of PU Foam Filled CFRP Cone Tubes
摘要
Abstract
A new type of CFRP filled with polyurethane (PU)foam was proposed for the vehicle front energy absorbing structures.The mechanical properties of PU foam and CFRP composites were obtained by the material property tests,and the results of quasi-static compression of PU foam filled CFRP were obtained.LS-DYNA was used to simulate the quasi-static collapse of composite materials. The simulation results are in good agreement with the experimental results,which verifies the cor-rectness of the finite element model and the material model of the composite filled structures.The re-sults show that the foam filled CFRP cone tubes have good energy absorption ability,and the filling structure specific energy absorptions are higher than that of the two materials used alone.关键词
