This study investigates the low velocity impact behavior and energy absorption capability of a hybrid 3D woven composite made from different fibers. The experimental results reveal the material's pseudo-ductile behavior and its higher capability to absorb impact energy when the glass plies are located at the back face of the laminate.
This study investigates the low velocity impact behaviour and the energy absorption capability of a hybrid 3D woven composite made from S2-glass (GF), T700 carbon (CF) and Dyneema fibres. The laminate was asymmetric, having a high concentration of CF on one side and GF on the other. Experimental results revealed a pseudo-ductile behaviour of the material and a higher capability to absorb impact energy when glass plies are located at the back face of the laminate. A detailed fractographic analysis by means of X-ray microCT and a FE model was included to explain such differences.
