Patent number: 10793478Abstract: Ceramic composite materials that are reinforced with carbide fibers can exhibit ultra-high temperature resistance. For example, such materials may exhibit very low creep at temperatures of up to 2700° F. (1480° C.). The present composites are specifically engineered to exhibit matched thermodynamically stable crystalline phases between the materials included within the composite. In other words, the reinforcing fibers, a debonding interface layer disposed over the reinforcing fibers, and the matrix material of the composite may all be of the same crystalline structural phase (all hexagonal), for increased compatibility and improved properties. Such composite materials may be used in numerous applications.Type: GrantFiled: July 9, 2018Date of Patent: October 6, 2020Assignee: ADVANCED CERAMIC FIBERS, LLC.Inventor: John E. Garnier
