Abstract

Composites of copper reinforced with 0.003 in. diam continuous tantalum filaments have been fabricated up to 0.38 volume fraction using the infiltration technique. Their elastic modulus, ultimate tensile strength, and yield strength have been found to be linear functions of the volume fraction of the filaments (V f ). The filaments elongated continuously until fracture occurred at the ultimate tensile strength of the composite given byS c =S f V f +σ″ m where σ″ m is the flow stress of the matrix at the fracture strain of the composite andS f is the ultimate tensile strength of the filament. It has been shown that the tensile strength of not only Ta−Cu but other ductile filament-ductile matrix systems can also be closely predicted.
