| Evolution of glass fibre-resin composites (polyester, epoxy and vinylester) after 30 years in a marine environment has been anticipated by the compilation of the Naval Construction Direction test results. This study showed that 120 degree C epoxy prepreg, in spite of improved initial performance, was more affected by water environment aging than other composites. Post-curing of epoxy and vinylester composites does not significantly improve resistance to water degradation except in the case of high temperature aging (60-70 degree C). |
