Abstract

Dynamic mechanical analysis(DMA) tests are conducted on styrene-based fiber reinforced shape memory polymer (SMP) to investigate its glass transition behaviors. Results show the properties of stiffness, damping and energy dissipation of the reinforced SMP are obviously better than that of the pure SMP during the process of glass transition. Static threepoint bending tests are performed on the reinforced SMP to determine its stiffness and strength. Results show the reinforcement in the reinforced SMP improve the material properties of stiffness and strength at the room temperature. Cyclic three-point bending tests are operated to study the material training effect of the reinforced SMP. A training evolutional equation is established to describe the material training effect of the reinforced SMP. Numerical results show the training evolutional equation is able to predict the material training effect of the reinforced SMP effectively.
