Abstract
In this study, composites of themoplastic polyurethane (TPU) reinforced with short fiber (Hibiscus Cannabinus) Kenaf (KF) were prepared via melt blending method using Haake Polydrive R600 internal mixer. The composites were prepared with different fiber loading: 10%, 20%, 30%, 40%, 50% and 60% (by weight), with the optimum blending parameters: 190 degrees C, 11 min, and 40 rpm for temperature, time and speed, respectively. Five samples were cut from the composite sheet. Mean value was taken for each composite according to ASTM standards. A 30% fiber loading has shown the best tensile strength. A 50% fiber loading has shown the best flexural strength, while the tensile and flexural modulus has shown an increasing trend. Impact strength has shown a decreasing trend with the increase of fiber loading.
