Fabrication and Performance of Shape Memory Epoxy Resin Composite

The carbon fiber reinforced epoxy resin composites with shape memory effect were manufactured via vacuum-bag curing process. The deformation-recovery shape memory tests of composite were performed above T(g) of the resin matrix. The results show that the shape fixation rate of the composite decreases from 98% to 91% and the recovery rate decreases from 98% to 91% while the mass fraction of carbon fiber increases from 0% to 50%. The shape fixation rate and recovery rate of the composite does not show any obvious and regular changes in the limited cyclic test.
