An analytical method is developed to determine the effective elastic moduli of a filled resin reinforced by randomly oriented chopped fibres, a three-phase composite such as a filled sheet moulding compound (SMC). The analytical results compare well with experimental results for both filled (glass/calcium carbonate/polyester) and unfilled (glass/polyester) SMC composites. The numerical results also illustrate the important influence of the filler phase on the composite stiffness properties.
