Abstract: An inseparable assembly includes a body having a plurality of plies stacked in face to face relation and bonded together, wherein each of the plurality of plies includes a ceramic matrix composite material having a first predetermined ductility. The assembly further includes a reinforcement including a metallic wire mesh bonded to said body so that at least a portion of the metallic wire mesh is positioned between two adjacent plies in the body. The metallic wire mesh has a second predetermined ductility greater than the first ductility.

Abstract: A method for making an environmentally stable, fiber reinforced ceramic matrix composite member includes use as a bonding agent of a ceramic precursor which transforms upon heating to a ceramic phase. The ceramic phase bonds together discontinuous material comprising ceramic particles, and reinforcing fibers at a relatively low processing temperature.

Abstract: A method of making a consolidated, reinforced composite member from a matrix mixture including a consolidation shrinkable discontinuous ceramic material, for example ceramic particles, and a selected amount of a particulate inorganic filler which will exhibit net expansion relative to the discontinuous material, the mixture being interspersed about reinforcing fibers. Subsequent consolidation of a preform of such materials can be conducted substantially at ambient pressure, without application of additional pressure, to provide an improved reinforced composite article.

Abstract: An oxide barrier coating for a reinforcing fiber is provided with a preselected microstructure and thickness through control of the concentration of metal salt in heat decomposable form as a precursor of metal oxide. In one form, the salt is a metal oxyhalide salt such as zirconium oxyhalide or hafnium oxyhalide. Fibers, such as ones of alumina, aluminasilicate or silicon carbide, having the coating of the invention are especially useful as reinforcing fibers for reinforced ceramic matrix composites.
