  • METHODS FOR REPAIRING A TURBINE AIRFOIL CONSTRUCTED FROM CMC MATERIAL
    Publication number: 20140241900
    Abstract: 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.

  • Method for modifying composite articles
    Patent number: 8715435
    Abstract: 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.
