Experimental and numerical study of hybrid effect in high performance quasi-isotropic thin-ply carbon/glass composites
Experimental and numerical study of hybrid effect in high performance quasi-isotropic thin-ply carbon/glass composites
This work studies the hybrid effect in a high performance Quasi-Isotropic (QI) carbon/glass hybrid composite under tensile loading. The hybrid effect is the enhancement in the strain at failure of the carbon fibres in a hybrid composite compared with a pure carbon composite. Different types of QI layups were tested and analysed to understand the interaction between the layers and the effect of the stiffness of the adjacent sub-laminates. A numerical model using the Finite Element method was proposed to evaluate the strain distribution considering an initial failure of one of the 0° carbon plies. The results show that the stiffness of the layers and the stacking sequence play an important role in the failure strain of the carbon plies; the layups with stiffer adjacent layers showed a higher hybrid effect.

Abstract
This work studies the hybrid effect in a high performance Quasi-Isotropic (QI) carbon/glass hybrid composite under tensile loading. The hybrid effect is the enhancement in the strain at failure of the carbon fibres in a hybrid composite compared with a pure carbon composite. Different types of QI layups were tested and analysed to understand the interaction between the layers and the effect of the stiffness of the adjacent sub-laminates. A numerical model using the Finite Element method was proposed to evaluate the strain distribution considering an initial failure of one of the 0° carbon plies. The results show that the stiffness of the layers and the stacking sequence play an important role in the failure strain of the carbon plies; the layups with stiffer adjacent layers showed a higher hybrid effect.
