In the recent trend, application of composite materials are continuously increasing from traditional application areas such as military aircraft, commercial aircraft to various engineering fields including automobiles, robotics arms and even architecture. Composite materials are used to meet the demand for lightweight, high strength/stiffness and corrosion resistant materials. An experimental investigation was conducted to study the effect of epoxy glass fibre and carbon fibre composites specimen subjected to in-plane tensile, compressive loading and Impact Loading. The laminated specimens with various volume fractions and fibre orientations that are in accordance with ASTM standards were used in this study. The laminates are prepared at different levels of fibre orientations. Three orientations viz 0° /90°, +45° /-45° and 30° / 60° were considered for studies. Epoxy glass and carbon composites are fabricated using Hand lay-up technique. The fabricated specimens are subjected to tensile, compressive and impact testing to find out the effect of mechanical properties viz., tensile, compression and impact at different orientations. The experimental results help us to identify the influence of fibre orientation and thickness of the influence of fibre orientation and thickness of the composite specimens on mechanical properties. © 2015 Elsevier B.V., All rights reserved.
