A modified bias-extension test method for the characterisation of intra-ply shear deformability of hybrid metal-composite laminates

The bias-extension test is one of the methods to characterise intra-ply shear behaviour continuous fibre reinforced composites including fabrics and unidirectional (UD) materials. For determination major mechanical properties metals, often a uniaxial tensile used. Combination these two for deformation hybrid metal-composite laminates proposed comparing method cross-plied prepregs woven fabric prepregs. effects material constituent, rate, preheat temperature normal pressure on are investigated. results indicate that constituents frictional responses depending processing parameters play critical role in characterisation laminate. angle measurement at four typical strains demonstrates support metal layers improves deformability by delaying onset wrinkling. This modified contributes better understanding process design wet (uncured) laminate manufacturing.
