Abstract
Shape memory polymer (SMP) and shape memory alloy (SMA) allow many design possibilities due to their controllable temperature-dependent mechanical properties. At elevated temperatures, SMP is at the rubbery state and thus exhibits high recovery strain but is lack of strength and modulus. On the other hand SMA is in austenite state at elevated temperatures, and can have very high modulus and strength but exhibits limited recovery strain. In this study, the shape memory composites (SMCs) are created by embedding SMA components (particles and fibers) into SMP matrices, which take advantage of the complementary properties of SMAs and SMPs. The SMA-particle and SMA-fiber reinforced SMP composites are designed through numerical simulations. The volume fractions of the SMA fillers were varied from 0-50% wt. With the additions of SMA fillers, the SMP composites exhibit significantly high modulus across the temperature regimes while maintaining the large actuation strain.
