Abstract
Elevated environmental awareness and an increasing concern with the global warming have stimulated the automotive, construction and packing industries to look for materials that can replace conventional synthetic fibers. Natural fiber appears as a good alternative since they are available in fibrous form and can be extracted from plant leaves, stalk, fruits and seeds at very low costs. In this study, the effect of sisal fiber surface treatment on mechanical properties was studied for natural sisal fibers. Sisal fibers were treated by alkali treatment, heat treatment and silane treatment respectively in order to enhance the interfacial adhesion of the fiber/polymer composite for mechanical properties improvement. Sisal fiber/polyethylene (PE) composites were prepared at fiber content of 10, 20, 30wt% by using twin screw extrude equipment and their mechanical properties such as tensile, flexural and impact strength were examined. Silane treated fiber (with content of 30%)reinforced composites showed 18% increase in tensile strength and 32% in Young’s modulus, while the alkali treated fiber (with content of 30%)reinforced composites performed 37% increase in flexural strength. However, in case of impact strength, the treatment has been found to cause a reduction. It was also found with increasing fiber content, tensile strength, flexural strength and modulus of the PP composites increased but impact strength and elongation at break decreased.
