Weathering of Filament-Wound Glass-Epoxy Tubes,

Abstract

Filament-wound glass-epoxy tubes manufactured for use as a rocket-launcher component have been used to study weathering of unstressed composites in a hot-wet environment. Tubes were exposed in three forms: as wound; after grinding to a fixed diameter; and after coating with alkyd paint. Burst pressure and torsional rigidity tests were used to study the mechanical effects of degradation. No significant deterioration could be detected mechanically after exposure in an unstressed state for two years at JTRU Innisfail, North Queensland. Minor loss of superficial glass fibre was observed on ground, uncoated specimens, but this relatively small deterioration was prevented by the use of the standard coating system. (Author)
