摘要

"Ceramic Composite Materials Containing Carbon Nanotube Infused Fiber Materials and Methods for Producing Them". The present invention in various embodiments relates to composite materials containing a ceramic matrix and a carbon nanotube infused fiber material. illustrative ceramic matrices include, for example, binary, ternary and quaternary metal or non-metal carbides, oxides, nitrides and carbides. The fiber materials may be continuous or cut fibers and include, for example, glass fibers, carbon fibers, metal fibers, ceramic fibers, organic fibers, silicon carbide fibers, boron carbide fibers, nitride fibers. of silicon and aluminum oxide fibers. The composite materials may further include a passivation layer overcoating at least the carbon nanotube infused fiber material and optionally the plurality of carbon nanotubes. The fiber material may be distributed evenly, non-uniformly or gradually in the ceramic matrix. Nonuniform distributions can be used to form and impart different mechanical, electrical or thermal properties to different regions of the ceramic matrix.
