Abstract

Unidirectional and cyclic tensile stress-strain testing has been carried out on continuous tungsten fibre reinforced copper composites, with fibre diameter from 11 to 48 Μm at a volume fraction of 0.37. In tensile tests the composites showed positive deviations from the rule of mixtures, the amount increasing with a decrease in fibre diameter and, therefore, interfibre spacing. This matrix strengthening continued to failure and was shown to be related in part to the matrix grain size.

In the cyclic stress-strain tests the matrix strengthening was approximately the same for all the composites and was greater than for the tensile tests. The strengthening could be accounted for by the formation of a substructure during cycling of approximately 0.5 Μm cell size.
