dc.description.abstract
Polymer matrix composites are already widely used in marine applications, but many of these are
overdesigned (glass/polyester pleasure boat hulls for example) and rarely heavily loaded. These
structures can last for 30 years or more and the main issue is how to dispose of them at the end of their
useful life. However, composite materials are increasingly being proposed for more highly loaded
structural components such as propellers and tidal turbine blades. For these structures, the effects of
seawater aging combined with mechanical loads are critical, as the commercial success of such
components depends on minimal intervention and high reliability. For this type of composite the tests
performed to evaluate degradation due to long term immersion are therefore critical. It is also essential
to have a robust approach in order to evaluate potential alternative materials, some of which (natural
fibre composite for example) show quite specific behaviour when wet. This paper will describe the
current approach to account for wet aging, its limitations and some proposals for an improved testing
methodology
