Abstract

Effect of fiber length on tensile strength of jute-fiber-reinforced polypropylene with several kinds of interfacial treatment K. Shima, K. Okubo & T. Fujii Department of Mechanical Engineering, Doshisha University, Japan Abstract Tensile strength was observed for natural jute-fiber-reinforced polymer (JRPP) having different fiber lengths and its surface treatment in order to evaluate the improvement of the mechanical property of natural composite. The composite was fabricated by the hot-pressing method with chopped jute fibers scattered randomly in polypropylene. Three kinds of fiber treatments were applied to change the interfacial strength between fiber and matrix, while the specimen has three different kinds of fiber lengths. Few different changes were observed in fiber strength, for any of the different kinds of treatment. Test results showed that JRPP has the most effective interfacial strength in order to improve tensile strength. The most effective interfacial strength shifted to a hlg
