ABSTRACT
The aim of the present experimental work is to investigate the mechanical property in terms of the tensile strength of Stainless Steel Wire Mesh (SSWM), Carbon Fiber Reinforced Polymers (CFRP) and Glass Fiber Reinforced Polymers (GFRP) when exposed to different elevated temperatures, ranging from 50°C to 300°C. Prior to testing all 21 coupons are subjected to the specified elevated temperature for 45 minutes and left for 24 hours to cool down up to ambient temperature. Stress-strain behavior, as well as failure modes are compared. The test results show that the decrease in the tensile strength of GFRP is more severe than those of CFRP and SSWM strips. The ultimate tensile strength of the SSWM, CFRP and GFRP at 300°C is decreased by about 22%, 20% and 29%, respectively, as compared to ambient temperature. The derived stress-strain relationship of SSWM, CFRP and GFRP at deferent temperature can be used as an input in numerical simulation of Reinforced Concrete (RC) member strengthened with SSWM, CFRP and GFRP.
