摘要
为了提高QP985高强钢的力学性能,选择热冲压方法来实现QP985高强钢与碳纤维增强复合材料(CFRP)的复合,并开展多层复合板三点弯曲试验。试验结果表明:与没有CFRP的钢板试样相比,铺设2层与4层CFRP试样的最大位移减小了10.12%与19.29%,吸收能量增大了4.76%与7.18%,弯曲角降低了22.49%与25.64%;CFRP可以起到明显的增强作用。
In order to improve the mechanical properties of QP985 high-strength steel,the hot stamping method is selected to realize the composite of QP985 high-strength steel and carbon fiber reinforced com-posite material(CFRP),and the three-point bending test of multilayer composite plates is carried out.The test results show that compared with the steel plate without CFRP,the maximum displacement of the steel plate with 2 and 4 layers of CFRP decreases by 10.12%and 19.29%,the absorbed energy increases by 4.76%and 7.18%,and the bending angle decreases by 22.49%and 25.64%.CFRP can play a significant strengthening role.
