Publication number: 20140241900Abstract: Methods for repairing a turbine airfoil constructed from a CMC material are provided via filling a cavity located in the turbine airfoil with a ceramic paste (e.g., including a ceramic powder and a binder), heating the ceramic paste in the cavity to remove the binder, thereby forming a porous ceramic material, and adding a molten ceramic material to the porous ceramic material. The cavity can be defined in an airfoil of the turbine airfoil (e.g., on a tip or cap of the airfoil). Intermediates formed during the repair of a turbine airfoil are also provided. The intermediate can generally include an airfoil comprising a CMC material, a cavity defined in the airfoil, and a porous ceramic material filling the cavity.Type: ApplicationFiled: May 5, 2014Publication date: August 28, 2014Applicant: General Electric CompanyInventors: Herbert Chidsey Roberts, III, Paul Edward Gray, Roger Lee Ken Matsumoto, Jeffrey H. Boy, Philip Harold Monaghan, Joseph Halada

Publication number: 20140199174Abstract: A method of forming a ceramic matrix composite (CMC) component, a CMC component and a tip member are provided. The method of form the CMC component includes providing a component preform having a first end, a second end, and a cavity, the cavity having a pre-determined shape and a first engagement surface. The method includes forming a tip member from a pre-consolidated composite material, the tip member having a second engagement surface generally conforming to the first engagement surface. The method includes directing the second engagement surface to the first engagement surface. The method includes consolidating the component preform and tip member. The ceramic matrix composite component is formed having a desired geometry and the tip member stays in place in the cavity during operation of the ceramic matrix composite component.Type: ApplicationFiled: January 11, 2013Publication date: July 17, 2014Applicant: GENERAL ELECTRIC COMPANYInventors: Herbert Chidsey ROBERTS, III, Gregory Scot CORMAN, Philip Harold MONAGHAN, Glenn Curtis TAXACHER

Patent number: 8715435Abstract: In certain embodiments of the present disclosure a method for modifying a composite article is described. The method includes positioning a plug made from composite material at a site on the composite article. The method further includes rotating at least one of the plug and the article at a rate of speed sufficient to form an inertia bond between the plug and the site of the composite article. The plug and the site are engaged to effect an inertia bond therebetween.Type: GrantFiled: September 9, 2011Date of Patent: May 6, 2014Assignee: General Electric CompanyInventors: Herbert Chidsey Roberts, III, Paul Edward Gray, Roger Lee Ken Matsumoto, Jeffrey H.

Patent number: 6431255Abstract: A ceramic casting shell mold having a pre-selected shape is described. It includes alternate, repeating layers of a ceramic coating material and a ceramic stucco, defining a total thickness of the shell mold; and a ceramic-based mat of reinforcing material disposed in the alternate, repeating layers of coating material and stucco. The reinforcing material for the mat is usually made from a ceramic material, and includes fibers having a bi-directional orientation. A method for making a ceramic casting shell mold is also described, as well as articles cast from such a mold, e.g., superalloy articles.Type: GrantFiled: July 14, 1999Date of Patent: August 13, 2002Assignee: General Electric CompanyInventors: Asish Ghosh, Robert Arthur Giddings, Frederic Joseph Klug, Paul Steven Svec, Philip Harold Monaghan

Patent number: 6352101Abstract: A ceramic casting shell mold having a pre-selected shape is described. The shell mold comprises repeating layers of a ceramic material which define its wall thickness and shape. At least one of the layers of ceramic material contains refractory whiskers which provide structural reinforcement to the shell mold. The whiskers are usually incorporated into a layer of the ceramic material which is disposed at a position off-center of the wall-thickness of the mold. A method for making a ceramic casting shell mold is also described, as are metal- or metal alloy components cast in these shell molds.Type: GrantFiled: July 14, 1999Date of Patent: March 5, 2002Assignee: General Electric CompanyInventors: Asish Ghosh, Frederic Joseph Klug, Philip Harold Monaghan, Paul Steven Svec, Robert Arthur Giddings
