Thermomechanical experiment and analysis on shape recovery properties of shape memory polymer influenced by fiber reinforcement

Shape memory polymers (SMPs) are currently investigated as potential materials for large deployable space structures [1, 2, 3]. The thermomechanical properties of these polymers significantly change on reaching their glass transition temperature, which yields the excellent feature of shape fixity and shape recovery . As another aspect, the modulus of these materials is not sufficient since they are polymeric materials. In actual applications, the fiber reinforcement is effective for ensuring the sustainability of the deployed structures.
However, while the fiber reinforcement has advantages for increasing the stiffness, it has a negative influence on the shape recovery behavior of SMPs. Experimental studies for shape memory polymer composite were conducted by Gall et al. [5, 6] for SiC powder-reinforced nanocomposite, Ohki et al.  for short-glass-fiber reinforcement, and Lan et al.  for SMP reinforced with plain-weave fabrics, and the increase of residual strain after shape...
