Abstract: This study deals with the experimental investigation of mechanical properties of glass fiber/epoxy composite material with variation in volume fraction of fiber in the composites. For manufacturing of composites combined hand layup and compression molding methods are used. The volume fraction of fiber is maintained about 40%, 50% & 60% in the total composition. With the help of experimental testing the mechanical properties such as tensile strength, shear strength. The results shows better mechanical properties with 50% of Volume fraction, however further increase in fiber content increases mechanical properties but composites starts delaminating. So at the end we got the material with 50:50 compositions is better for application with optimum strength.

Keywords: composite materials, Volume Fraction, Mechanical properties, Delamination.
