玄武岩纤维增强木质层合板低速冲击力学响应研究

Mechanical Responses of Basalt Fiber-reinforced Wood Laminates at Low-velocity Impact

  • 摘要: 建立了适合于玄武岩纤维增强木质层合板在低速冲击载荷作用下的一种损伤模型,运用Hashin失效准则作为层内损伤的起始判据,线性刚度衰减理论模拟层内损伤的演化,二次名义应力准则模拟层合板的层间损伤。通过ABAQUS建立玄武岩纤维增强木质层合板低速冲击有限元模型,利用上述损伤模型分析了纤维层数和纤维铺层对层合板冲击性能的影响。结果表明:层合板抗冲击性能随着玄武岩纤维层数的增加而提高;对只含1层的玄武岩纤维的层合板,玄武岩纤维排列方式0°/90°/0°/90°s优于0°/45°/90°/45°s的抗冲击性能。

     

    Abstract: A sort of damage model has been established for basalt fiber-reinforced wood laminates under low-velocity impact load. Hashin failure criterion has been used as the initial criterion for intra-laminar damage, linear stiffness decay theory has been applied to simulate the evolution of intra-laminar damage, and the quadratic nominal stress criterion has been employed to simulate inter-laminar damage. A finite element model has been established by ABAQUS software for analysis of low impact response of basalt fiber-reinforced wood laminate. Two kinds of effects, such as the number of fiber layers and fiber pavement, have been analyzed for impact performance of the laminate by the damage model. The results show that the impact resistance of the laminate increases with the increase of the number of basalt fiber layers. For laminate containing only 1 layer of basalt fibers, the impact resistance of basalt fiber arrangement 0°/90°/0°/90°s is superior to that of 0°/45°/90°/45°s.
