摘　　要：使用玻璃纤维、碳纤维和芳纶纤维3种平纹纤维织物和乙烯基酯树脂,通过真空导入工艺制备了4种不同混杂组合的平纹织物纤维增强层合板,并对其进行了摆锤冲击试验;通过有限元模拟软件Abaqus对试验过程进行仿真建模,并与试验结果相比较。结果表明:低速冲击荷载下,纯玻璃纤维试样所受冲击力最大,吸能效果最差;碳纤维/芳纶纤维加入混杂后,冲击力、吸能效果均得到提升。其中:G2/A4/G2试样缓冲效果最好,冲击力减少54. 4%;C2/G4/C2试样吸能效果最好,吸能提高了34. 1%。Abaqus模拟结果与试验结果较为接近,可较好地反映复合材料的损伤过程。In this paper,four kinds of plain weave fibre reinforced laminates with different hybrid modes are prepared by vacuum induction process with glass fibre,carbon fibre,aramid fibre and vinyl ester resin.A pendulum impact experiment is carried out and compared with the simulation results by finite element simulation software Abaqus.The results show that pure glass fiber specimens suffer the greatest impact force and have the worst energy absorption effect under low-speed impact load.When carbon fiber/aramid fiber is mixed,the impact force and energy absorption effect are improved.Among them,G 2/A 4/G 2 sample has the best cushioning effect,and the impact force is reduced by 54.4%.C 2/G 4/C 2 sample has the best energy absorption effect,and the energy absorption is increased by 34.1%.Abaqus simulation results are close to the experimental results,which can better reflect the damage process of composite materials.
