FIBER-REINFORCED MULLITE COMPOSITE MATERIAL DISPERSED AND REINFORCED WITH GRANULE AND PRODUCTION OF THE SAME COMPOSITE MATERIAL

摘要

PURPOSE:To obtain the title composite improved in breaking toughness by reinforcing mullite with a combination of fiber with granule dispersion. CONSTITUTION:The objective composite can be obtained by reinforcing mullite with a combination of fiber with granule dispersion, thus being made up of a mullite matrix, fiber and granules of the same or different kind as or from said fiber both dispersed in said matrix. To produce this composite, mullite granules to be the matrix are dispersed in a solution containing an organometallic polymer to prepare an impregnating solution. Thence, fiber is continuously passed through this solution to evenly impregnate the fiber with said solution. The resultant fiber is then made into a laminate and the organometallic polymer contained therein is insolubilized, the resulting laminate is sintered in an Ar or N2 gas under normal or higher pressure.
