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 paper examines the effects of glass fibre configuration and epoxy resin type on the response of glass fibre epoxy-based fibre metal laminate panels. These lightweight materials are excellent candidates for use in transportation applications, where mass is a major factor in design and materials selection. Interfacial bond strength was characterised through single leg bend testing and revealed varying failure characteristics for different epoxy configurations and surface treatments. A combination of bead blasting and silane treatment provided the best surface treatment for the aluminium, while SE84 epoxy resin gave superior adhesion properties compared to Prime 20ULV. Blast tests were performed to investigate the effect of bond strength on panel response under localised and more uniformly distributed air-blast loading conditions. Dimensionless analysis and failure mode identification were used to show that both fibre configuration and bond strength played a role in blast response but the bond strength (and particularly resin type) was more prominent.
