FLEXUAL BEHAVIOR OF GFRP SHEETS IMMERSED IN WATER BASED ON MICROSTRUCTURE ANALYSIS

Abstract

Abstract: The glass fiber reinforced polymer (GFRP) sheets were immersed in deionized water and saline solution at room temperature. The durability of GFRP sheets in clear water and saline solution was studied by changes in mass gains, modulus of rupture, modulus of elasticity, and aging thickness. The results showed that the mass gains increases with time and then tend to be stable in both solutions. The mass gains of GFRP sheets in deionized water are about 2 times than that in saline solution. The modulus of rupture and modulus of elasticity of GFRP sheets which marinated in deionized water and saline solution increase in the early stage and then decline. The aging thickness of GFRP sheets immersion in deionized water was higher than that immersed in saline solution at the same immersion time.

Key words: glass fiber reinforced polymer (GFRP), saline solution, flexual behavior, durability, aging thickness
