The carbon fiber composite mandrel was conducted thermal oxygen ageing tests at 170、185、200℃ for one month. Through the mechanical properties tests, Fourier infrared spectroscopy (FTIR), and scanning electron microscope (SEM) analysis of the mandrel sample at different ageing stages, the macro properties, micro characteristics, and the relationship between macro and micro properties were studied, and the change laws of mandrel properties with ageing time were obtained. The results show that the accelerated thermal oxygen ageing will further increase the curing degree of the mandrel and enhance its mechanical properties. While during the thermal oxygen ageing process, there are cracks, powders, and holes in the epoxy resin matrix in the outer layer of the mandrel. The interface adhesion between epoxy resin and glass fiber becomes worse, and the epoxy resin matrix becomes brittle, which will damage the mechanical properties. Under the action of these two factors, the mechanical properties of mandrel increase occasionally and then decrease as a whole.
