Abstract: The present work is aimed at studying glass fibre reinforced epoxy angle-ply laminated composites under in-plane and out-of-plane loads. Three symmetric laminates were fabricated at different combination of fibre ply orientations through a simple hand layup technique. The prepared laminates were characterized for tensile and flexural strength measurements according to the ASTM standards D3039 and D7264, respectively. Symmetric laminates consisting of fibre plies orienting in the direction of applied load have demonstrated greater resistance against tensile loads, whereas laminate system consisting of adjacent plies oriented in different angles promoted binding strength of the matrix which in turn resulted in enhanced flexural strength values.
