【Abstract】 In this paper, a set of formulae decribing the elastic properties of an unidirectional composite lamina are derived based on a macromechanics model, according to theory of anisotropic elasticity. The formula of E_2c and C_12c are symmetrical in forms and simple on structure. They are easy to calculate and have definite physical meaning. It has been proved that these formulae are quite accurate ard can be used in engineering design of composite materials.更多还原
