✦ Synopsis

The influence of matrix degradation on fiber-mode mechanical properties of unidirectional composites is considered. In this case the strength of the composite reduces to the strength of a bundle of fibers. The longitudinal Young's modulus is evaluated as a nonlinear function of applied stress. In the case of a degradated matrix all the failure criteria reduce to the maximum stress criterion. The statistical parameters of the Weibull distribution of the fiber strength are evaluated from commercially available experimental data for commonly used materials.

The use of aluminum as matrix material for continuous fiber reinforced composites has been investigated for over 20 years, with varying degree of success: industrial applications of these materials remain very limited. This paper describes the development of a practical method of producing near net
