Spandex Fiber Reinforced Shape Memory Polymer Composites and their Mechanical Properties

In this current study, spandex fiber with high elasticity and high recovery ratio were added into shape memory epoxy resin. Compared with pure shape memory resin, the Young’s modulus increases by 28.2%, tensile stress by 49.7% and fracture strain by 16.4% in samples with 20 vol% spandex fiber, while recover time reduces by 36s in samples with 40 vol% spandex fiber.
