Diskrete Wahrscheinlichkeitsverteilungennuity may be sharp or gradual. In general, the interface is an essentially bidimensional region through which material parameters, such as concentration of an element, crystal structure, atomic registry, elastic modulus, density, and coefficient of thermal expansion, change from one side to another.

The availability of a large variety of carbon fibers (Chap. 2) and an equally large variety of polymer matrix materials (Chap. 3) made it easier for carbon fiber reinfor

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 ., a r

Diskrete Wahrscheinlichkeitsverteilungenhis is the rule of mixtures, which works reasonably well for predicting the longitudinal elastic constants. Unfortunately, the same cannot be said for the strength of a fiber composite. It is instructive to examine why the rule of mixtures approach does not work for strength properties.

Whatever the field may be, the final limitation on advancement depends on materials. Composite materials in this regard represent nothing but a giant step in the ever constant endeavor of optimization in materials.
