Abstract
The present invention relates to a method of forming ceramic matrix composite bodies comprising a parent metal reacting with an oxidant to produce an oxidation reaction product which infiltrates a loose unbonded mass or a preform comprising a filler material mixture. Specifically, the filler material mixture used in the method of the present invention comprises a material having varying compositions, sizes and/or shapes of filler material within the mass or preform. By utilizing a filler possessing varying compositions, sizes and/or shapes, enhanced packing of the filler material is achieved which may result in improved properties, such as erosion resistance, corrosion resistance, etc. Further, the use of filler material containing varying sizes and/or shapes may also enhance the growth rate of oxidation reaction product, thereby reducing processing times for formation of the resultant ceramic composite body.
