In order to explore the effect of fiber orientation angle on the Young’s modulus of fiber reinforcement polymer (FRP) composites, from the basic theory of elastic mechanics, a procedure which can be applied to evaluate the elastic stiffness matrix of FRP composite as an analytical function of fiber orientation angle (0-90o), is developed in Mathematica environment. Results indicate that Young’s modulus of the composites strongly depends on the fiber orientation angles. A U-shaped dependency of the Young’s modulus of composites on the inclined angle of fiber is found, which agree well with the experimental results and numerical simulation. The shear modulus was found to have significant effect on the Young’s modulus.
