Microstructure and properties of multifibre composites

Abstract

In the study microstructure and properties of composite multifibre copper-base wires are presented. A decision was made to produce wires with "soft' fibres (Al) and "hard" fibres (Fe). In the study the phenomenon occurring on the border of Al-Cu was also analysed. The produced Cu-Al and Cu-Fe composites presented ordered microstructure with the fibres uniformly distributed in the copper matrix. The composites underwent plastic consolidation to the degree which provided satisfactory mechanical and electrical properties. During the drawing the fibres deformed proportionally with copper matrix therefore their content in the cross section remained unchanged.
