Recently, shape memory polymer as one of functional materials has received much attention and its mechanical properties have been investigated. Shape memory polymer of polyurethane series has the glass transition temperature (Tg) around the room temperature. Based on the large change in modulus of elasticity above and below Tg, the material has excellent shape memory property. In this study, for the wider applications in the fields of industry, medical treatment, welfare and daily life, the glass fiber reinforced shape memory polymer was developed. The specimens with different fiber weight fractions, which are SMP bulk, 10wt%, 20wt%, and 30wt%, were prepared, and their mechanical properties and stress-strain-temperature relations were investigated experimentally. Then, the influence of fiber weight fraction on the shape memory effect was evaluated. It was found that mechanical properties and the shape memory effect of the developed materials heavily depend on both temperature change and the fiber weight fraction
