The aim of the paper is to establish a simple approach to predict the elastic modulus and tensile strength of the plain woven composite lay up in the orientations of ±45° and 0/90°. Through testing the lamina of±45°orientation and lamina of 0/90°orientation, the mechanic performance data concerning the material properties, such as the elastic modulus, the tensile strength and maximum strain were obtained. Through the formula proposed in this paper, the elastic modulus and tensile strength of lamina lay up in the orientations of ±45° and 0/90° will be obtained. The results basically agree with those from testing and those computed by classical lamination theory. Comparing with CLT, the approach, asking for fewer data, is simpler, and can be applied to the preliminary design.
