Experimental Investigation on the Mechanical Properties of Green Hybrid Sisal and Glass Fiber Reinforced Polymer Composites

摘要

Composites made fromrenewable sources have become important alternative materials for designing and manufacturing engineering and industrial products. Natural fiber composites have become superior materials compared to conventional fiber composites, due to their easy manufacturing process, high-fiber content, reduction in the polluting base content, lightweight, and incineration. Environmental cleanliness is an increasing concern to look for sustainable alternative materials that can replace conventional materials that are being used now. Natural fibers constitute a good alternative reinforcement material, since they are readily available in fibrous form, and can be extracted at very low costs. In the present study, environment friendly green composites have been prepared and the mechanical properties of these composites are evaluated. The results indicated a significant improvement in the tensile, flexural, and impact properties of the hybrid composites, and the effect of hybridization reduces the environmental effects. The internal structure of the broken surface, delamination of fibers, and the failure morphology are analyzed using the scanning electron microscopy analysis.
