Abstract
Fire retardant GRP sheets based on tetrachlorophthalic acid- modified polyester resin subjected to either artificial or natural weathering undergo two types of surface deterioration (breakdown at the glass-resin interface resulting in fibre prominence and surface microcracking) 2.5 to 3 times faster than conventional sheets. Exposure to humidity-temperature cycles produces fibre prominence at comparable rates for both types of GRP sheets, but does not induce formation of surface microcracking. The surface of the fire retardant sheets protected with weather-resistant poly (vinyl fluoride) (PVF) film does not undergo breakdown when subjected to accelerated or natural exposures.
