Predicting the Transverse Conductivity of Unidirectional and Bidirectional Filamentary Composites.

Abstract

This Phase II report of the grant AFOSR 78-3640 presents studies of analytical models capable of predicting the transverse conductivity of unidirectional and bidirectional filamentary composites to an accuracy of several per cent. The models are based on adaptations of the Rayleigh solution and one-dimensional conduction analysis. Values of the conductivity defined by Han and Cosner (by numerical methods) and presented in the Phase I report of this grant study are used as the basis for judging the validity of the models. The adaptations can be used to predict, within several per cent, the transverse conductivity of a variety of types of fiber-matrix systems, while retaining the ability to isolate first-order effects of the principal variables in a relatively direct manner.
