A finite difference type of approach is proposed for the study of the elastic properties of fibre and particulate reinforced composites. The effects of the fibre modulusE 1 and aspect ratio (I/d) on the composite modulus are studied. In that respect, the ratio (E1/Em/(I/d), whereE m is the matrix modulus, is shown to be an important index of short fibre composites. Our results for the dependence of the composite modulus onE 1,I/d and volume fraction of the fibres are compared to available experimental data on foams and particulate filled polymers. A good agreement with experiment is found, which is much better than that obtained with the help of the widely used semi-empirical Halpin-Tsai equation.
