Abstract:

Unidirectional glass fibre layers have been hybridized with unidirectional self-reinforced polypropylene layers. Tensile tests and microCT have been performed to investigate and understand the properties of these hybrids. The tensile behavior is a combination of the stiff and strong glass fibre layers and the ductile self-reinforced layers. A hybrid effect of +10% was observed for the failure strain of the glass fibre layers. Tensile strength and absorbed energy showed mainly negative hybrid effects. This is attributed to the glass fibre misalignment, which is induced by the shrinkage forces of the self-reinforced layers. MicroCT measurements verified this hypothesis.
