Última Dégradation de matériaux composites dans un environment marin: Nouveaux materiaux et methodes d'essais ArchiMer Pomies, F; Carlsson, L; Choqueuse, Dominique; Davies, Peter. 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...

Role sur les proprietes hygrothermiques ArchiMer Perreux, D; Suri, C; Varchon, D; Oytana, C. The mechanical behaviour of polymer based glass fibre composites depends on the damage level and the amount of moisture present. Two anelastic damage models, both adapted to the mechanical properties of epoxy and polyester matrix polymers, are proposed. A coupling effect between the kinetics of damage and moisture level is shown.
