Excellent Adhesion

This papers examines the interfacial fracture properties of a new fibre-metal laminate based on glass fibre reinforced polypropylene (GFPP). Tests have shown that excellent adhesion between aluminium and GFPP can be achieved by incorporating a maleic-anhydride modified polypropylene interlayer between the composite and aluminium layers. Single cantilever beam tests have shown that the fracture energy of these systems initially increases with loading rate and then decreasing. In spite of this, the fracture energy is extremely high at all rates.

The aim of this paper is to investigate the interfacial fracture properties of a novel fibre-metal laminate based on a unidirectional glass fibre reinforced polyamide 6,6 composite. Interfacial fracture tests using a modified single cantilever beam geometry have shown that good adhesion between the aluminium and glass fibre polyamide plies can be achieved using a simple stamping operation. Further testing has shown that the basic fracture properties of this system do not depend on the cooling rate employed during consolidation of the laminates.

This study investigates the influence of improved adhesion, resulting from maleicanhydride modification of the polypropylene matrix, on transverse cracking in 0/906/0 glass fibre-reinforced polypropylene laminates. It was shown that the characteristic damage state in cross-ply polypropylene/glass laminates, i.e. the saturation level of transverse cracks, is independent of fibre-matrix adhesion and corresponds very well with a predicted value using a shear-lag analysis.
