As a smart material, shape memory polymer composites (SMPC) can be restored to its original state by specific stimuli such as thermal stimulation, electrical stimulation, magnetic field stimulation. However, it is difficult to use in environments that require high mechanical properties due to its low strength. In this study, an SMP composite material was prepared by adding CF and graphite. As the filler, carbon fiber (CF) in the form of fibers and graphite in the form of plates were used. Thermal conductivity with different the type and content of fillers was measured. Then, The shape fixing rate and recovery rate were analyzed, and the mechanical strength was analyzed through the tensile strength.
