Abstract
In this paper mechanical behaviors of jute fiber reinforced polypropylene composite prepared by injection molding are studied. The tensile strength, flexural and impact strength of samples with different fiber contents are investigated by comparing three kinds of composites with fiber contents of 10,20 and 30wt%. The tensile strength, flexural and impact strength of samples with different fiber length are also investigated by comparing three kinds of composites with fibers chopped approximately to 3mm, 5mm and 10mm in length. The results show that the tensile and flexural properties are improved to some extent after jute fibers added, as compared to pure polypropylene, while its impact strength is lower. The flexural strength and moduli of composites increase with fiber content increasing, but the impact strength decreases. The flexural strength and moduli of composites increase with the increase of the fiber length, but the impact strength decreases.
