maritime craft, because wood was becomingincreasingly scarce and expensive, timber was aslosing favour with many boat builders and ownersbecause wooden boats were easily degraded byseawater and marine organisms and thereforerequired ongoing maintenance and repairs that can beexpensive. The earliest attempts to fabricate boat hullwith FRP composites was in 1947 when twelve smallsurf boats were made for the UNITED STATESNAVY. Most maritime craft are built using glassreinforced polyester (GRP) composites; althoughsandwiched composites and advanced FRP materialscontaining carbon are aramid fibers with vinyl esteror epoxy resin matrices They are commonly used forhigh performance structural applications.
