Method for producing composite materials
Abstract
Abstract A method for continuously manufacturing in air high strength metal matrix composites reinforced with a plurality of parallel layers of unidirectional filaments comprising positioning a plurality of filament reinforced aluminum matrix monolayer tapes in a stack, pressing the stack between at least one pair of rollers heated to a predetermined temperature at pressures of approximately 100-10,000 psi to reduce its thickness and cause densification, said temperature being lower than the liquidus temperature of the aluminum matrix but being sufficiently high, in combination with the pressure, to cause bonding of the aluminum matrix of each tape to the filaments embedded therewithin and to contiguous portions of the adjacent tapes.
