Glass fibre reinforced polymer is widely used in various applications for their improved properties. In order to further enhance the properties of GFRP laminates they can be combined with other material through the introduction of filler materials to get better properties. Development of advanced composites with improved properties is of utmost important, especially composite which are light in weight but with better tensile and flexural properties is the need of the hour. When the lamina plies are stacked at various angles, the lay-up is called a laminate. Continuous-fibre composites are normally laminated materials in which the individual layers, plies, or laminae are oriented in directions that will enhance the strength in the primary load direction. In our dissertation work we are adding graphene in various percentages to the GFRP composite laminate so as to increase its strength and mechanical properties. These properties will then be tested by carrying out tensile and flexural tests on the GFRP laminate according to the ASTM standards. For tensile test and flexural test ASTM values are found using D3039 and D7264 respectively. The effect of addition of graphene is studied by these tensile and flexural properties. This will help us to find out the ability of graphene powder to improve the mechanical properties of GFRP laminates.
