Abstract
The effect of moisture, heat and ultra violet (UV) radiation on the flexural modulus and flexural strength olf high strength polyethylene (HSPE) fibre composites have been studied and the effects compared to those for glass reinforced plastic (GRP) composites. Composite panels were fabricated from two types of HSPE fabrics (Spectra Trademark 955 and Spectra Trademark 985) made with 1000 Series Spectra fibres and an E-glass fabric (style 7781) and an epoxy or a cyanate ester resin. The resulting panels were exposed to synethetic sea water, UV-condensation cycles (ASTM D4329-84), and hot salt fog (ASTM B117-90) and then tested in flexure to determine the effect of the exposure on the flexural properties.
