The purpose of this paper is to investigate the tensile property of laminated epoxy resin composites reinforced by carbon fiber plain woven fabric after accelerated aging for different period of time at 150°C. For this purpose, the tensile tests of laminated resin composite samples without aging and aged 60 hours, 120 hours, 180 hours, at 150°C were carried out. The damage forms of composite samples tested were investigated. The experiment result indicates that the accelerated aging process has an obvious effect on the tensile strength of composite samples. The average tensile strengths of composite samples aged 60 hours, 120 hours, and 180 hours period of time at 150°C are 87.31%, 88.61%, 79.05% of average tensile strength of composite samples without aging, respectively. The observation of the damage form of samples tested shows that when accelerated aging, the resin in the composite samples is damaged and the adhesive force between fiber bundles and epoxy resin decline, which makes the ability of fiber and resin bearing the tensile load together decreases.
