Abstract

Abstract: This study investigates the static-bursting and low-velocity impact property of the sandwich flexible composites. The sandwich flexible composites were composed of a three-dimensional (3D) fabric filled flexible polyurethane (PU) foam core, and two compound laminates as face sheet. Foam filled fabric reinforced sandwich flexible structure were designed to explore the effect on the static-bursting and low-velocity impact properties of the sandwich flexible composites. The results represent that the static-bursting strength of the foam could increase to 324% by reinforced with the filling-resistant 3D fabric. The fiber blending ratio of the filling resistant 3D fabric had a prominent influence on the static-bursting strength. Finally, the sandwich flexible composites with the filling resistant 3D fabric have great elongation that is favorable to the low-velocity impact strength.
