Abstract: As a new kind of smart materal, shape memory polymer has some advantages, such as low density, large recovery ability, superior fabrication property and low cost and which has been widely used in textile industry, medical, aerospace and microelectronics engineering. In this paper, short carbon fiber reinforced trans-1,4-polyisoprene shape (TPI) memory polymer composites was fabricated with the weight fraction of 0, 5%, 7%, 9%, 11%, 13%, respectively, using a new preparation technology. The mechanical properties of short carbon fiber reinforced shape memory polymer composites are analyzed by tensile tests and their failure mechanism was also studied based on the fracture surface morphology of composites.
