Abstract

The transverse impact of 3D biaxial spacer weft-knitted reinforced fabric composite is performed with a split Hopkinson pressure bar. The load versus displacement history of the composite under different impact velocities is obtained. The failure load and failure deformation both increase with the increasing of impact velocity. The energy absorption of the composite also increases with the increasing of impact velocity. The failure mode of the composite is compression failure in the front side and tension failure in the distal side. The matrix crack, fiber pullout and form interface debonding form the main failure mode for transverse impact loading. The composite has no delamination either for quasi-static loading or for transverse impact loading.
