Abstract

In this chapter we consider the results of incorporating fibers in a matrix. The matrix, besides holding the fibers together, has the important function of transferring the applied load to the fibers. It is of great importance to be able to predict the properties of a composite, given the component properties and their geometric arrangement. We examine various micromechanical aspects of fibrous composites. A particularly simple case is the rule of mixtures, a rough tool that considers the composite properties as volume-weighted averages of the component properties. It is important to realize that the rule of mixtures works in only certain simple situations. Composite density is an example where the rule of mixtures is applied readily. In the case of mechanical properties, there are certain restrictions to its applicability. If more precise information is desired, it is better to use more sophisticated approaches based on the theory of elasticity.
