A step-by-step method of rule-of-mixture of fiber- and particle-reinforced composite materials

摘要

A new method of rule-of-mixture is presented for predicting the mechanical properties of fiber- and particle-reinforced composite materials. The composite material is composed through a hypothetical process in which the matrix is reinforced one-by-one with reinforcing materials (fibers or particles). The mechanical properties of the composed material are obtained step-by-step using the cylinder model for fiber-reinforced materials and the sphere model for particle-reinforced materials. Results obtained by the present method are compared with those of other methods and experimental results. It is found that, for the longitudinal modulus, the present method gives equally good prediction as other methods. For the transverse modulus and shear modulus, the results obtained by the present method show better agreement with experimental results.
