Abstract: Composites are made by addition of one or more materials combined at macroscopic level. By varying the percentage of composition of materials the strength and toughness can be obtained as per the end applications. The present work is to fabricate an E-glass epoxy composite using MY740 epoxy along with varying percentages of CaCO3 as filler material. The filler materials are added at different percentages of 2.5 wt% and 5 wt% and the mechanical properties such as tensile strength, impact strength, flexural strength and fracture toughness of the composites are determined. Using the graphs, the failure modes of the composites are determined. It is found that the addition of fillers increases the tensile strength, but decreases the impact energy. Varying strengths are obtained at Flexural and Fracture test based on the filler percentage and temperature. ANSYS modelling is carried out to verify the fracture toughness of the composite. The SEM analysis is also carried out to determine the failure at micro-structural level.
