Experimental Investigation of Flexural Strength of E-glass/epoxy Composites

Abstract-Fiber reinforced plastic composites now a day’s acts like driving force to dynamise the structural applications with the hiding features of less weight and higher strength. In addition to this, the glass fiber reinforced epoxy composites, like any other fiber reinforced polymer composites, offer many advantages over the conventional structural materials due to their excellent resistance against bending. These alternatives plays dignified role in multidisciplinary sections of engineering. The performance of the composites can further be improved by adding fillers to them. The present work aims at using wollastonite as a filler material and this work also includes the experimental evaluation of flexural properties of series of such CaSiCo3 (wollastonite) filled glass-epoxy composites (for both woven and chopped mat type). It is observed that maximum bending load taken by each specimen varies directly with the increase in filler percentage and also found that flexural strength gradually increases as the percentage of filler addition is increased
