Abstract
Abstract A preconsolidated tape of continuous, high strength filaments in a metal matrix is coated with a layer of adhesive polymer and cut into shaped plies. The coated plies are stacked in a mold and resin bonded together by the application of heat and pressure. Many of the desirable physical properties of a diffusion bonded metal matrix article are also found in the resin bonded metal matrix article of the subject invention. Also, the use of preconsolidated adhesive coated plies eliminates the need for high diffusion bonding pressures and temperatures, thereby cutting the time involved for the bonding and molding operation by a factor of 8 in some instances.
