Simplified equations are presented for the elastic properties of randomly oriented short fiber-glass composites. The suggested equations for the Young's modulus, the shear modulus and the Poisson ratio are given in terms of the fiber-glass content and the Young's moduli of the constit uents. The equations are applicable for fiber-glass volume fractions in the range 0.1 to 0.4. The theoretical results are compared with experimental values, and the achieved good correlation, shows the utility of the pro posed approximations.
