摘要：Properties of hemp fibre reinforced unsaturated polyester composites following exposure to accelerated weathering conditions have been studied. Exposure to ultraviolet (UV) radiation and UV radiation plus condensation resulted in immediate loss in weight which stabilised following prolonged exposure times. The same exposure led to initial decline in tensile properties of hemp fibre composites, but the decline in properties also stabilised following prolonged exposure and these materials seemed to perform fairly well in these conditions. The decline in strength and modulus was quite similar, unlike immersion in water where the reduction in modulus was more pronounced than the reduction in strength. Discolouring of composites following exposure to these conditions was identified as an issue with these composites.
