electrical matrix composite materials containing carbon nanotube infused fiber materials and methods for their production

摘要

Electrical Matrix Composite Materials Containing Carbon Nanotube Infused Fiber Materials Methods for Producing Them The present invention relates to composite materials containing a metal matrix having at least one carbon nanotube infused fiber material. Metallic matrices include, for example, aluminum, magnesium, copper, cobalt, nickel, zirconium, silver, gold, titanium and various mixtures thereof. Fiber materials include glass fibers, carbon fibers, metal fibers, ceramic fibers, organic fibers, silicon carbide fibers, boron carbide fibers, silicon nitride fibers and aluminum oxide fibers. The composite materials may also include a passivation layer coating at least carbon nanotube infused fiber material and optionally carbon nanotube applicability. The metal matrix may include at least one additive which enhances the compatibility of the metal matrix with carbon nanotube infused fiber material. The fiber material may be distributed evenly, not uniformly or in a gradient in the metal matrix. Non-uniform distributions can be used to impart different mechanical, electrical or thermal properties to different regions of the metal matrix.
