Abstract: This study examines the effects of different layering sequences on the mechanical properties of flax/basalt fiber hybrid reinforced composites. The resin transfer molding process was used to prepare pure flax fiber, pure basalt fiber, and flax/basalt fiber hybrid reinforced composite laminates with two different stacking sequences. Low-velocity impact and post-impact bending tests were performed to reveal the influence of layering sequences on the mechanical properties and failure mechanisms of the hybrid composites. The study found that in the low-velocity impact test, the mechanical properties of the hybrid composites were between pure flax fiber and pure basalt fiber composites. [B4F4]S exhibited a higher peak force than [F4B4]S(where B denotes the basalt fiber layer, F denotes the flax fiber layer), and the energy absorbed by [B4F4]S was higher. In the three-point bending test, the mechanical properties of the undamaged hybrid composites were between pure flax fiber and pure basalt fiber composites. However, after impact damage, the post-impact bending strength retention rates of both hybrid composites were higher than those of pure flax fiber and pure basalt fiber composites, and under the same impact energy, the post-impact bending strength retention rate of [F4B4]S was higher.
