Investigation of mechanical property of eco-friendly natural filler (ground nut, saw dust and hybrid shell) reinforced epoxy based composite

Abstract

Development and advancement of materiel will open the new research area for the use of different eco-friendly filler reinforced epoxy composites. These composite are environment friendly and also prevent the harmful effect of polymer based composite over human life and environment. This study examines the potentials of ground nut shell, sawdust and hybrid bio filler as reinforcement in epoxy matrix. Initially, an experiment was carried out on the mechanical characteristics of the natural fillers indifferent proportions of its volumes such as 10, 20 and 30, in both treated and untreated cases. 20%-volume fraction show the most optimum result. Besides, an analysis using Maleic acid has also been made on the filler surface modification. In comparison with other cases of treatment, the treatment using Maleic acid is more effective in enhancing the flexural, tensile and impact properties of the composite. The synergetic impact in the treatment is an important cause for the improvement of the properties. The effect also strengthens adhesion and stress transfer along with reinforcement. SEM is used for filler material evaluation process.
