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

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.
