Estimating the term…
This invention provides carbon composite materials, which comprise metal carbide particles, at least the particle surfaces or the entirety of which are metal carbides, synthesized in situ from a metal source, i.e., at least one member selected from the group comprising metal particles, metal oxide particles, and composite metal oxide particles, and a carbon source, i.e., a thermosetting resin, dispersed in a carbon, carbon fiber, or carbon/carbon fiber matrix, and contain no free metal particles. This invention also provides a method for producing such composite carbon materials, which enables the production of carbon composite materials having a high coefficient of friction, high thermostability, and abrasion resistance.

Friction materials, which comprise metal carbide particles, at least the particle surfaces or the entirety of which are metal carbides, synthesized in situ from a metal source, i.e., at least one member selected from the group comprising metal particles, metal oxide particles, and composite metal oxide particles, and a carbon source, i.e., a thermosetting resin, dispersed in a carbon, carbon fiber, or carbon/carbon fiber matrix, and contain no free metal particles.
A method for producing friction materials comprising metal carbide particles dispersed therein, wherein at least one of metal particles, metal oxide particles, or composite metal oxide particles is dispersed in a thermosetting resin to obtain a slurry mixture, carbon fibers are impregnated with the slurry mixture, and carbonization and calcination are carried out to carbonize the thermosetting resin to generate metal carbides in situ, at least the particle surfaces or the entirety of the particles of which are metal carbides.
