Resumo: 	The change in composite material properties when these are exposed to a marine environment is of considerable importance to both designers and users of these materials. In this paper new materials are first studied, composites composed of a glass fibre reinforced thermoplastic PPS matrix. It is shown that their poor interfacial resistance to moisture ingress compromises severely the advantage of using a matrix which does not absorb moisture. In the second part of the paper the application of two non-destructive test techniques for following damage development, based on ultrasonic wave propagation and vibration (modal) analysis, are described. These are complemented by first results from a study using fracture mechanics tests to characterise delamination resistance.
