N2 - Hybridisation of two composites has the potential of tailoring properties to reach a composite structure with advantages of both constituents where the drawbacks are lessened. The current work reports this practice for self-reinforced polypropylene (SRPP) composites and glass fibre to create an interply hybrid composite with enhanced stiffness and ductility. The effect of glass fibre volume fraction, matrix adhesion, and layup, was studied as the parameters to affect progressive failure through pseudo-ductility. Hybrids with up to 6.5% glass fibre volume fraction showed pseudo-ductile behaviour. However, matrix adhesion and layup interfered with this effect. It was found that composites with low adhesion matrix exhibited higher pseudo-yield strain, and for the laminates with an interleaved layup, the maximum glass fibre volume fraction for progressive failure increased by 100%. The impact behaviour of the composite laminates also demonstrated that brittleness of the glass fabric reduces the energy absorption capability of the laminates compared to SRPP composite of the same thickness.
