Composite materials are engineered materials, are made from two or more constituent materials with significantly different physical and chemical properties. FRP composites are slowly emerging from the realm of advanced materials and are replacing conventional materials in a variety of applications. In the present work the mechanical properties E_x, E_y, v_xy, v_yz, v_zx and G_xy of continuous fiber GFRP angle ply lamina (Specially orthotropic lamina) are determined for three different fiber volume fractions using finite element method. A finite element model incorporating the necessary boundary conditions is developed and is solved using commercially available FEA package. A neural network model was developed using Neuro Intelligence package. The data set obtained from the FEA package was employed for training, validating and testing the neural networking model. The results obtained from the ANN architecture have been compared with the FEM results and some conclusions have been made.
