Effects of tropical weather on the compression properties of pultruded gfrp composites

Glass fibre reinforced polymer (gfrp) is a composite material, which consists of polyester thermosetting resin as matrix and glass fibres as reinforcement. Pultruded gfrp is mainly used as structural sections and as structural rehabilitation and repair material. It was observed that the current requ...
