Abstract:
1. A process for manufacturing a disk shaped component comprising fabricating a disk shaped component using a composite material having at least a first material and a second material, wherein said first material is disposed at and proximate to a center portion of said disk shaped component and said second material is disposed at and proximate to a rim of said disk shaped component, wherein said first material comprises a first coefficient of thermal expansion, a first stress value and a first oxidation resistance, and said second material comprises a second coefficient of thermal expansion, a second stress value and a second oxidation resistance, wherein said first coefficient of thermal expansion is in a range of 6 ppm/° F. to 8 ppm/° F. and said second coefficient of thermal expansion is in a range of 4.5 ppm/° F. to 6.5 ppm/° F., said first stress value is greater than said second stress value and said first oxidation resistance is less than said second oxidation resistance.
