Abstract
This work studies the hybrid effect in high performance Quasi-Isotropic (QI) composite plates under tensile loading. The hybrid effect is the enhancement in strain at failure of the carbon fibre layers in the hybrid composite compared with a pure carbon fibre composite. Different types of QI lay-ups 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 finite element method was proposed to evaluate the strain distribution through the thickness considering a premature failure of one of the 0° carbon plies, the strain gradient was calculated as well as the average strain concentration in the undamaged 0° carbon ply. Correlations between pseudo-yield strain, strain concentration in the undamaged 0° carbon ply and stiffness of the sub-laminates were identified. Additionally, microscopic observations of specimens interrupted before the final failure were studied to recognise the damage mechanisms and measure the fragmentation distance.
