  • Fabrication of composite articles having an infiltrated matrix
    Patent number: 6280550
    Abstract: A composite article is fabricated by preparing a porous first region piece having a first reinforcement material with no matrix, and rigidizing the first reinforcement material to form a porous first coated preform. At least one second-region layer of a second reinforcement material having no matrix is applied in contact with at least a portion of the first coated preform. The second reinforcement material is rigidized, to form a second coated preform. A second-region matrix material is deposited into at least some of the porosity of the second coated preform. The reinforcement material may be silicon carbide fibers, and the infiltrated matrix may be silicon carbide.
