▎ 摘　　要

Seven groups of different layering angles of Graphene oxide/Carbon fiber (GO-CF) hybrid reinforced shape memory composites are prepared by vacuum infiltration hot pressing system. The layering angles are respectively [0 degrees](4), [+/- 15 degrees](s), [+/- 30 degrees](s), [+/- 45 degrees](s), [+/- 60 degrees](s), [+/- 75 degrees](s), and [90 degrees](4). The shape fixation ratio, shape recovery ratio, and shape recovery driving force of GO-CF hybrid reinforced shape memory composites are investigated. The composite with the layering angle of [0 degrees](4) has the minimum shape fixation ratio of 90.9%, the maximum shape recovery ratio of 97.6%, and the maximum recovery force of 2.83 N. Compared to [0 degrees](4), the composite with the layering angle of [90 degrees](4) has the 9.13% higher shape fixation ratio, but it has 16.1% lower shape recovery ratio and 59.4% lower recovery force. The microstructure of the composites is characterized and the microstructure of seven groups of composites is satisfactory. Therefore, the matrix within each group of composites has a similar effect on the shape memory properties of the composites. With the layering angle increased, the fiber resilience in the axial direction (X-direction) and the accumulated internal stress gradually decrease. With the layering angle increased, the shape fixation ratio and recovery time of GO-CF hybrid reinforced shape memory composites increase, while the shape recovery ratio, recovery force, and recovery rate decrease.
