Hybridization Effects on Charpy Impact Behavior of Basalt/Aramid Fiber Reinforced Hybrid Composite Laminates

Basalt/aramid hybrid fiber reinforced composite laminates were prepared to examine the effect of hybridization on Charpy impact behavior of aramid fiber reinforced composite laminates. The effect of position of basalt layers on the impact behaviors was also investigated by preparing hybrid composite laminates with the substitution of basalt layers into different positions. The position change of basalt layers in the hybrid configurations were resulted in variations in the impact behavior. The impact energy and impact damages strictly depended on impact behavior of fiber at impacted surface due to the difference between deformation characteristics of basalt fiber and aramid fiber. When the basalt layer was at the impacted surface, the hybrid composite laminates exhibited a lower impact energy. This was attributed to the restriction in deformation of aramid layers. The position of basalt layers resulted in variations in the impact behavior of hybrid composite laminates. (C) 2016 Society of Plastics Engineers
