Abstract
A system and method for ceramic doping of carbon fiber materials is disclosed. A carbon fiber preform may be made of carbonized oxidized PAN fibers and may be placed in contact with a nanoparticle suspension having nanoparticles and a dispersion medium. The nanoparticles may impregnate the carbon fiber preform, causing it to become a doped carbon fiber preform. The doped carbon fiber preform may be densified. The doped carbon fiber preform may be densified by conventional CVI processing techniques. The doped carbon fiber preform may be densified by thermal gradient CVI.
