One of the major being the air craft Industry where it is used for the manufacture of the radomes. The manufacturing of the E-glass epoxy composite in the laminate form involves the design of the mould and the manufacturing of a composite laminate using the 8mould. The laminate is manufactured by table tap pre-preg method manually and then subjected to a compressive load for thorough distribution of resin in respective lamina and then finally subjected to curing by gradual heating towards high temperature in a closed control thermal oven. Then test the manufactured laminate for its tensile strength and Young’s modulus. These days lot of research is directed to understand the fatigue failure behavior of laminated composites. The materials usage is increasing in all sorts of engineering applications due to high specific strength and stiffness. Fibre reinforced composite materials are selected for weight critical applications and these materials have good rating as per the fatigue is concerned. Composite materials are anisotropic in mature and their failure behaviour is different from that of isotropic materials. Tensile tests were performed and balanced symmetric laminates of (± 0)8 , (± 20)8 , (± 30)8 , (± 40)8 , (± 45)8 , (± 55)8 ,(± 60)8 Degree orientation. The tensile test were performed on the laminated in CIPET, Hyderabad laboratories and Saint Gobain Vetrotex India Private Ltd., The aim of the paper is the deflection to be induced in the specimen is estimated by conducting the deflection tests on the specimens of laminates (± 0)8 , (± 20)8 , (± 30)8 , (± 40)8 , (± 45)8 , (± 55)8 ,(± 60)8
