Resumo: his paper evaluates the tensile properties in the axial direction of GFRP pipes aged under high pressure (73 and 89 bar) and high temperatures (60°C and 93°C) through time. The tests were performed according to ASTM D3039-17. The modulus of elasticity showed the highest degradation compared to the condition without aging. The aging affected the tensile modulus of elasticity much more significantly than the tensile strength. The aging conditions at 89 bar were the most aggressive, generating macroscopic delaminations and the greatest losses in tensile properties.
