THROUGH THICKNESS REINFORCEMENT FOR CMC
A method for making a ceramic matrix composite component includes densifying a fibrous preform of the component with a ceramic matrix to form an intermediate component (10); infiltrating a hole (14) in the intermediate component (10) with an infiltrate material (22) comprising a solid and a metallic alloy whose reaction forms a carbide, silicide, boride or combination thereof, heating the infiltrate material (22) to a temperature in excess of a melting point of the metallic alloy; and sequentially cooling regions of the hole (14) starting from an interior end of the hole (14) to the outer surface (11) of the intermediate component (10) to form a solidified through-thickness reinforcement element (26). The hole (14) extends in a through-thickness direction and is open to an exterior surface of the intermediate component (10).
