Abstract
High-performance metal matrix composites of copper, aluminum, and/or titanium are produced by embedding nanocarbon reinforcement into metal foil or sheet which is concurrently laminated into a multilayer structure to produce high-performance materials for thermal management, enhanced electrical conductivity, armor products and high-strength composite structures.
Claims14
A method of making a metal matrix composite comprising embedding carbon reinforcement material directly between two metal layers, the two metal layers consisting of a first metal layer and a second metal layer;
- laminating a foil or sheet consisting of aluminum directly to the first metal layer of the metal matrix composite;
- and treating the laminated aluminum foil or sheet with plasma electrolytic oxidation to produce a hard corundum surface.
A method of making a metal matrix composite, comprising:
- providing a first metal sheet and a second metal sheet;
- providing a carbon reinforcement material;
- placing the carbon reinforcement material directly between the first metal sheet and the second metal sheet and pressing the respective metal sheets together to make a sandwich structure;
- passing the sandwich structure through an ultrasonic consolidation process to embed the carbon reinforcement material to the respective metal sheets and to join the respective metal sheets together;
- laminating a third metal sheet directly to the first metal sheet of the sandwich structure;
- and
- treating the third metal sheet with plasma electrolytic oxidation.
