Evaluation of Mechanical Behaviour of Glass Fibre-Epoxy with Graphene Nano Powder Laminates

This paper presents the fabrication and evaluation of Glass fiber reinforced-epoxy with addition of graphene nano powder laminates as per the ASTM (American Society for testing and Materials) standards. The composites are made by using epoxy as a structural matrix material which is reinforced by glass fibre toenhance the strength. The strength of composite material depends on the amount of fibre and matrix content which are indicated by fibre matrix volume fractions. The fibre orientation plays a vital role in the strength of composites. Symmetric and anti-symmetric cross ply laminates of uni directional E-Glass Fiber reinforced epoxy are fabricated by using hand layup process with the help of moulds of required shape. The mechanical properties of tensile, impact and flexural strengths of fabricated composites are found by conducting experiments such as tensile, impact and flexural tests respectively. Burn test is performed on laminates to find the volume fractions of both fiber and matrix to calculate orthotropic properties of symmetric and anti-symmetric cross ply laminates. Deflections and stresses of symmetric and anti-symmetric cross ply laminates are found using numerical analysis ANSYS software. Experimental and numerical analysis results are compared. After ascertaining the superiority in strengthof symmetric cross ply laminate, Graphene nano powder as filler material is added to them and analysed. The improvements of strength for the symmetric laminate with graphene nano powder are presented
