In this paper, five groups of graphene oxide-carbon fiber/epoxy resin (GO-CF/EP) composites with different curing temperatures were prepared by the vacuum infiltration hot-press system (VIHPS). These five groups of composites presented satisfactory macroscopic morphologies. However, the microstructure of the GO-CF/EP composite cured at 110 degrees C was satisfactory because there was no obvious infiltration defect. The damping properties of these composites were tested by force hummer method. When the curing temperature was 110 degrees C, the composite had a maximum damping ratio of 0.21%, while the composite cured at 130 degrees C had a minimum damping ratio of 0.13%, which decreased by 35.89%. In addition, when the curing temperature was higher, the damping properties of the composite were also worse than that of the composite cured at lower temperature. Because the curing temperature was different, the infiltration effect of resin in the fiber was various, and the energy dissipation ways in the composite material was different, which was reflected in the damping properties.
