N2 - This paper investigates the mechanical behaviors of carbon fiber fabric reinforced shape memory polymer composite (SMPC). As well-known, the major advantages of shape memory polymers (SMPs) are their extremely high strain recovery, low density and low cost, etc. However, relatively low modulus and low strength are their intrinsic drawbacks. Fiber reinforced SMPC which may overcomes the above-mentioned disadvantages is studied here. The investigation is conducted by means of four types of tests, namely, (1) dynamic mechanical analysis (DMA), (2) static three-point bending, (3) shape recovery test, and (4) optical microscopic observations of deformation mechanism at microstructural level. Results reveal that SMPC exhibits a higher glass transition temperature (Tg) and a higher storage modulus than that of pure SMP. The SMPC shows nonlinear viscoelasticity at a temperature range between T g-20°C and Tg+20°C. At/above Tg, the shape recovery ratio of SMPC upon bending is above 90%. The shape recovery properties of SMPC become relatively stable after some packaging/deployment cycles. Additionally, the fiber micobuckling is the primary mechanism in bending of SMPC.
