Abstract: A method of treating a ceramic matrix composite article, including selecting an article having a ceramic composition formed by a process comprising an initial melt infiltration at an initial temperature with an initial infiltration material, whereby said article has at least one treatable feature. A portion of the ceramic composite is removed from a region abutting the treatable feature to form a treatment region. A treatment material including a reinforcing fiber is positioned in the treatment region and densified by a first melt infiltration with a first infiltration material including silicon. The first melt infiltration is performed at a first temperature lower than the initial infiltration temperature of the initial melt infiltration.

Abstract: A method for additive manufacturing an object is disclosed. The method includes converting an encoded file for a set of components to a text-based component toolpath file; creating and encoding a set of serialization (SN) files for characters in a part marking geometry; and converting encoded SN files to a set of text-based SN toolpath files. The method then generates a combined print file from the component toolpath file and the SN toolpath files to include both component and SN scan paths, wherein generating includes combining location and part marking details from a part SN location script with SN geometries from the SN toolpath files to create a modified SN toolpath file for a part marking.

Abstract: The present disclosure is directed to a method for forming a passage in a composite component. The method includes forming a cavity in a fiber preform. The cavity forms a portion of the passage. The method also includes inserting a core into the cavity and placing one or more fiber plies onto the fiber preform to form a fiber preform assembly. The method further includes thermally processing the fiber preform assembly and densifying the fiber preform assembly to form the composite component. The method also includes removing the core from the composite component.

Abstract: A method of making a preform and preform formed by the method. The method includes providing a first pre-preg ply including at least a first fiber and a first resin. The method also includes providing a second pre-preg ply including at least a second fiber and a second resin over at least a portion of the first pre-preg ply. Heat or electromagnetic radiation is used to at least partially cure the first and second resins to form a cured preform. Heat is applied to pyrolyze at least a portion of the resin of the cured preform to form a pyrolyzed preform. A mechanical stimulus including at least one of controlled drying, local explosions, or ultrasonic energy is applied to the pyrolyzed preform. The mechanically treated pyrolyzed preform is subsequently densified by melt infiltration to form a densified preform.

Abstract: Methods for preparing ceramic matrix composites using melt infiltration and chemical vapor infiltration are provided as well as the resulting ceramic matrix composites. The methods and products include the incorporation of sacrificial fibers to provide improved infiltration of the fluid infiltrant. The sacrificial fibers are removed, such as decomposed during pyrolysis, resulting in the formation of regular and elongate channels throughout the ceramic matrix composite. Infiltration of the fluid infiltrant can then take place using the elongate channels resulting in improved density and an improved ceramic matrix composite product.
