  • In this paper, the mechanical properties of glass fiber/epoxy vinyl ester resin (GF/epoxy VER) composite after hygrothermal aging were studied. The GF/epoxy VER composites laminates were fabricated by vacuum assisted injection molding technology. According to the stress characteristics of composite pressure vessels during service, bending and shearing samples were made by water cutting technology. Considering the working environment of pressure vessel, accelerated aging tests were carried out on the samples soaked in water to analyze the changes of the mass and mechanical properties of the composites at different temperatures and periods. Results show that bending and shear properties of composite materials decrease with the increase of water immersion time. The effect of temperature on the properties of composites is more significant than that of soaking time. If immersed in 90 ℃ water for 6 weeks, the shear strength, flexural strength and flexural modulus of the composite are reduced to half of the initial value.
