Bending Property of Carbon Fiber Reinforced Polystyrene Shape Memory Composite

A kind of carbon fiber reinforced polystyrene shape memory polymer composite was developed for improving the stiffness of polystyrene shape memory polymer.The bending recoverability and bending property of the composite were investigated.The results indicate that the bending recoverability of the composite was higher than that of polystyrene and the maximum recovery ratio reached 98%.The maximum bending load of the composite was 113 N,about 145% of that of the polystyrene at 25 ℃.And it was 39 N,about 108% of that of the polystyrene at 45 ℃.The carrying capacity of the composite was super than that of the polystyrene after plastic failure.
