Mechanical Properties Evaluation of Unidirectional Glass Fibre Reinforced Aluminium Sandwich Laminate

Glass fibres consists of around 54% silicon dioxide reinforced Aluminium Sandwich laminates have the potential in meeting the demands of structural applications of the aerospace and other industries. These laminates are developed mainly to achieve the target of production of light weight structures, which comparatively has a good strength. The combination of fibre and metal offers an excellent mechanical property for the laminates and the same is improved by different fibre orientation and layer formation. The performance of laminate improves by choosing the right fibre orientation. In the present study, the sandwich laminate is laid up by using Aluminium (AA 1050) and Glass Fibre Unidirectional (UD) Ply as layers. The laminate consists of 5 layers of UD glass fibre as the outer and middle layers, Aluminium as the second and fourth layer. The fabricated sandwich laminates are able to introduce an ease of fabrication and affordability concept, which is also used as a substitute material for metallic components with light weight and corrosion resistance. The fabricated laminate is tested under various loading conditions like tensile, flexural and impact. The result shows that the tensile property of the laminate is greater than its flexural and impact properties. The defects of the surface topography of the broken specimen is analysed using Scanning Electron Microscopy.
