Patent number: 10458653Abstract: An assembly comprising a ceramic matrix composite component, a ceramic insert, and a ply and a method for producing the same. The ceramic matrix composite component may comprise silicon carbide fibers in a silicon carbide matrix. The ceramic inset may be adjacent to the ceramic matrix composite component. The ply may at least partially cover the ceramic insert such that the ceramic insert may be sandwiched between the ply and the ceramic matrix composite component, and the ply may extend beyond the ceramic insert in at least one direction so that the ply is joined to the ceramic matrix composite. The ply may comprise at least one layer of silicon carbide fibers or carbon fibers in a silicon carbide matrix.Type: GrantFiled: June 3, 2016Date of Patent: October 29, 2019Assignees: Rolls-Royce Corporation, Rolls-Royce North American Technologies, Inc.Inventors: Ted J. Freeman, Thomas D. Nixon, Sean E. Landwehr, Aaron D. Sippel, Donald W. Reinhart

Patent number: 6855428Abstract: The present invention is a composite material and process to produce same. That material comprises a fibrous structure which is initially predominantly coated with elemental carbon; that fibrous structure is then subsequently predominantly coated with at least one ceramic material, e.g., boron carbide, which is non-reactive with silicon. The composite material also comprises a silicon matrix which is continuous and predominantly surrounds the fibrous structure, which has been initially predominantly coated with elemental carbon and subsequently predominantly coated with at least one ceramic material. The matrix which has a fine grain crystalline structure of predominantly 20 microns or less in size. The at least one ceramic material is discontinuous within that matrix. The fibrous material pulls out of the elemental carbon, which initially predominantly coats that fibrous structure, when the composite is subjected to fracture.Type: GrantFiled: June 2, 2003Date of Patent: February 15, 2005Assignee: B. F. Goodrich CompanyInventors: Sai-Kwing Lau, Salvatore J. Calandra, Thomas D. Nixon, Edward R. Stover
