In this study, the dynamic impact properties of the 3D glass woven fabric reinforced composites (PG) and the hybrid composite of PG with the carbon cloths were investigated. And the fracture mechanisms were estimated by cross-sectional observation. From these results, the energy absorbed mechanism could be clarified. And the effect of the carbon layer and the stacking sequence was clarified. It was found that PG with the carbon cloths had higher impact property than PG only. Moreover it was clarified that the absorbed energy obtained from the anterior load-deflection curve can be improved by stacking the carbon layer on the top or bottom or both side, and the absorbed energy from the posterior curve was improved with that on bottom side.
