Composites are made to utilize the various properties of the constituent materials and to optimize the required physical, mechanical and thermodynamic properties. The fact that brittle solids can be toughened by brittle materials was demonstrated in 1982 and some later developments have been summarized. Quite significant progress has been made in the area of the modulus dependence on the volume fractions, moduli, sizes, and thicknesses of the fibers and laminates. Many models, such as the Shear-lag, Laminated plate, Eshelby and finite element methods have been applied to understand the mechanical properties of the composites with reasonable success. But a clear understanding of how the interfaces control the properties of the composite is still needed. The authors present here the simulation results obtained from a spring-network model for the mechanical properties of the composites. Agreement with available data and previous theories was obtained.
