The main objective of the study was to investigate the effect of various filler materials on inter laminar shear properties of glass/epoxy composite materials. In this study three different filler materials were selected (SiO2, TiO2, Glass powder) for high strength and stiffness applications. The physical properties are also studied with the composites. The fiber volume fraction of material plays vital role in preparation of composite laminates. The fabrication method used was conventional hand lay-up process depending upon the resin system hot temperature cure and room temperature curing processes were selected. The short beam shear test was carried out to test inter laminar shear strength (ILSS). The short beam shear test results inter laminar shear strength and to find the significant influence of filler material on characterization of glass fiber reinforced plastic (GFRP) composite. The test results shown that high shear strength were observed with silicon dioxide(SiO2) filler material and with 10% of silicon dioxide filler material shows maximum ILSS value.
