A metal matrix composite comprising nanotubes; a method of producing the same; and a composition, for example a metal alloy, used in such composites and methods, are disclosed. A method for continuously infiltrating nanotube yarns, tapes or other nanotube preforms with metal alloys using a continuous process or a multistep process, which results in a metal matrix composite wire, cable, tape, sheet, tube, or other continuous shape, and the microstructure of these infiltrated yarns or fibers, are disclosed. The nanotube yarns comprise a multiplicity of spun nanotubes of carbon (CNT), boron nitride (BNNT), boron (BNT), or other types of nanotubes. The element that infiltrates the nanotube yarns or fibers can, for example, be alloyed with a concentration of one or more elements chosen such that the resulting alloy, in its molten state, will exhibit improved wetting of the nanotube material.
A metal matrix composite, the composite comprising:
The metal matrix composite of any preceding claim, wherein the plurality of nanotube reinforcements is present in a volume fraction of between about 40% by volume and about 60% by volume of the metal matrix composite.
The metal matrix composite of any preceding claim, wherein the metal comprises at least one of:
The metal matrix composite of any preceding claim, wherein the plurality of nanotube reinforcements comprises a continuously spun nanotube yarn or a continuous nanotube tape, and wherein the metal comprises copper alloyed with at least one of:
The metal matrix composite of any preceding claim, the metal wetting the plurality of nanotube reinforcements.
The metal matrix composite of any preceding claim, comprising a first layer of metal coating the plurality of nanotube reinforcements, and a second layer of metal coating the first layer of metal.
The metal matrix composite of any preceding claim, wherein the continuous structure of the metal matrix composite comprises at least one of a continuous yarn, a continuous wire, a continuous cable, a sheet, and a preformed nanotube shape.
An interdiffused alloy composite resulting from heating of a composite structure comprising a metal including one or more of chromium, scandium, titanium, vanadium, hafnium, niobium, aluminum, tungsten, molybdenum, tantalum, nickel, copper, cobalt, iron, silicon, ruthenium and zirconium, coated onto a carbon structure, sufficiently to infiltrate the metal into the spaces surrounding the carbon structure.
