Durability of Glass Fibre Reinforced Polymer Pultruded Profiles: Comparison Between QUV Accelerated Exposure and Natural Weathering in a Mediterranean Climate

This paper presents the results of an experimental study about the durability of E-glass fibre reinforced polymer (GFRP) pultruded profiles when exposed to environmental degradation agents. Small-scale coupons obtained from commercial GFRP profiles, made of either unsaturated polyester or vinylester resins, were exposed to natural ageing in the city centre of Lisbon, an urban Mediterranean environment, during 42 months (3.5 years) and to...
