Abstract

In this project, three experiments have been conducted to test on the effects of layers of glass fibre sheet reinforcement on shape memory polyurethane. The matrix (shape memory polyurethane) is tough but relatively weak that can be complemented by reinforcement of stiffer glass fibre. Since there are shape memory polymer and alloy in the market, shape memory polymer is chosen as material for this project is because it has high strain/shape recovery ability, easy to process as compare to the shape memory alloy. Glass fibre in other hand, is also light, cheaper and high shape fixity as compared to the other addictive and modifier. The first experiment which is tensile test has resulted that the 2-layer of glass fibre sheet reinforced shape memory polyurethane has the highest ultimate tensile strength. However, it exhibited the lowest percentage of elongation at break. Recovery test is conducted to investigate the recovery rate at different degree of reinforcement. Result from the recovery test also shown that the reinforced shape memory polyurethane exhibited a higher recovery rate as compared to the one without reinforcement. At last, the elongation and load test is to observe the degree of elongation on the specimen during the deformation of the specimen at constant load and temperature. 2-layer of glass fibre sheet reinforced shape memory polyurethane also proved to have the highest resistance to elongate at high tempearature.
