Abstract
A fiber reinforced glass matrix composite has a glass matrix or glass ceramic and a plurality of primary and secondary reinforcing fibers dispersed in the matrix. The primary fibers may be continuous or discontinuous. The secondary fibers are discontinuous. The secondary reinforcing fibers which are shorter than the primary fibers fill regions of the matrix not filled with the primary reinforcing fibers. The composite may be made by uniformly distributing the secondary reinforcing fibers in a dispersant. A glass powder is mixed in a carrier liquid to create a slurry and the secondary reinforcing fibers and dispersant are slowly added to the slurry so the fibers uniformly disperse as they are added. A binder is also added to the slurry. A continuous fiber is impregnated with the slurry and the impregnated fiber is dried to remove the carrier liquid. The impregnated yarn is cut to a suitable length and molded by a suitable molding method to form a fiber reinforced glass matrix composite.
