ABSTRACT:
A method for continuously manufacturing in air aluminum 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, placing the stack between platens heated to a predetermined temperature, pressing the stack between the platens at pressures of approximately 100-10,000 psi to reduce its thickness to 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 said matrix to said filaments and to contiguous portions of adjacent tapes and removing the densified composite from between the platens.
