    Abstract: Thermally-induced shape memory plastic composite (SMPC) is an intelligent material which can respond to the external temperature stimulation. Compared with the traditional thermally-induced SMPC, the high thermal conductivity graphene(GR)-carbon fiber(CF) hybrid reinforced thermally-induced SMPC has a series of excellent properties, such as excellent shape memory performance, high specific strength and strong thermal conductivity. In recent years, people have paid much attention to it and carried out relevant research. Starting from the historical origin and applications of shape memory material, this paper focuses on the research frontier of GR-CF hybrid reinforced SMPC, and reviewes the domestic and foreign research status of the composite material in four aspects: infiltration law, molding process, shape memory performance enhancement rule and bending failure rule. Combined with the existing research situation, the future research direction of the thermally-induced SMPC is pointed out.
