Embodiment 1

[0134] Example 1: Formation of carbon nanotube-infused carbon fiber ceramic matrix composites. Silicon carbide matrix composites were prepared by colloidal processing of chopped carbon nanotube-infused carbon fibers. Chopped carbon fibers were Grafil, Inc. (Sacramento, CA) 34-700, 12k filaments infused with carbon nanotubes with an average length of 55 μm prepared by the continuous infusion method described above. Fibers were chopped to 3mm length. By mixing a colloidal mixture of silicon carbide nanoparticles and binder (SiC nanoparticles + binder = 50% by weight) with chopped carbon nanotube-infused carbon fibers (50% by weight) , to prepare silicon carbide matrix composites. The resulting mixture of silicon carbide nanoparticles, binder, and carbon nanotube-infused carbon fibers was placed in a test brick press model. To cure the adhesive and produce green ceramic tiles, the mold containing the mixture was heated to 175° C. for 30 minutes under a pressure of 2500 psi. A...

Abstract

In various embodiments, composite materials containing a ceramic matrix and a carbon nanotube-infused fiber material are described herein. Illustrative ceramic matrices include, for example, binary, ternary and quaternary metal or non-metal borides, oxides, nitrides and carbides. The ceramic matrix can also be a cement. The fiber materials can be continuous or chopped fibers and include, for example, 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 can further include a passivation layer overcoating at least the carbon nanotube-infused fiber material and, optionally, the plurality of carbon nanotubes. The fiber material can be distributed uniformly, non-uniformly or in a gradient manner in the ceramic matrix. Non-uniform distributions may be used to form impart different mechanical, electrical or thermal properties to different regions of the ceramic matrix.
