ABSTRACT:
The preparation of multilayer filament reinforced consolidated articles is found to be possible because of the unique properties of RF plasma sprayed deposits. Pursuant to this method, a first layer of plasma deposited foil is made with a rough upper surface. A layer of closely spaced aligned reinforcing filaments is positioned on the rough surface. A second foil of RF plasma deposited metal is formed in and on the layer of filaments. A second layer of filaments is positioned on the second foil and a third foil is formed in and on the second layer. The three foils are integrated because of the strong tendency of the RF plasma sprayed metal to penetrate through, wet the fibers, and bond to the layer underneath.
