| Abstract: | Hybridization is an effective way to improve the toughness of composites. In this paper an experimental investigation on impact behaviour of hybrid composites is conducted by using Charpy impact test. The variation of impact strength and impact toughness index of C/K and C/G hybrid composites of different matrices with hybrid ratio and interface number is revealed. The dynamic hybrid effect is also investigated from different aspects. Meanwhile, the estimating model for impact strength is established and the estimated values are in good agreement with experimented ones. Using this models the hybrid effect coefficients based on different definitions are organically related.This provides basis for further study of impact constitutive equation. |
