Abstract
A glass matrix/ceramic fiber reinforcement composite is prepared from a yarn formed by spinning glass fiber and ceramic fibers lengths together, to form a bicomponent yarn. The yarn is weavable and spinnable, and accordingly may be prepared in fabric forms, or in windings, of predetermined shape. The precursor is melted by heating to the temperature of the melting point of glass, which fused the glass into a continuous matrix, surrounding the ceramic reinforcement.
