  • Patent number: 5118560
    Abstract: A discontinuous carbon fiber reinforced glass matrix composite includes a glass matrix, a plurality of carbon reinforcing fibers dispersed in the matrix, and a plurality of boron nitride reinforcing particles dispersed in the matrix. The composite may be fabricated by mixing glass powder and boron nitride reinforcing particles in a carrier liquid to create a slurry and adding a binder to the slurry. A continuous multifilament carbon fiber yarn is impregnated with the slurry and dried to remove the carrier liquid. The impregnated carbon fiber yarn is cut to a suitable length and is molded in a suitable molding means to form a carbon fiber reinforced glass matrix composite article.
