Problems solved by technology

Embedding rods / tubes in such channels will prevent impregnating material from filling them, but embedding in or removing from channels can be time-consuming and laborious
Also, during removal of the quartz rod / tube from the channel, the surface of the channel may be damaged, which may negatively affect the cooling performance of the part

Embodiment Construction

[0031] Reference will now be made in detail to embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the invention. For example, features illustrated or described as part of one embodiment, can be used on another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents. As used herein, the terms "first," "second," and "third" may be used interchangeably to distinguish one element from another, and are not intended to indicate the position or importance of each element. The terms "upstream" and "downstream" refer...

Abstract

Laminate components and methods for forming the same are provided. In one exemplary aspect, one or more features are laser cut into or along a laminate component or laminate sections thereof. The features are laser cut into or along the laminate component in an atmosphere. In this manner, and oxide layer is formed on the laser cut surfaces of the future. The features are laser cut into or along the laminate component or laminate sections thereof prior to an infiltration process, such as melt infiltration or chemical vapor infiltration. Accordingly, when the laminate component is infiltrated with an infiltration material, the infiltration material is prevented from infiltrating therethrough.

Description

technical field [0001] The present disclosure generally relates to laminated components and methods of forming the same, and more particularly, the present disclosure relates to CMC laminated components for turbine engines and methods of forming the same. Background technique [0002] To increase the efficiency and performance of gas turbine engines to provide increased thrust-to-weight ratio, lower emissions, and improved specific fuel consumption, the engine turbine is tasked with operating at higher temperatures. As engine operating temperatures increase, components formed from Ceramic Matrix Composite (CMC) have been developed to replace components typically formed from superalloys, such as combustor liners, shrouds, nozzle segments, etc. . In many cases, CMC components offer improved temperature and density advantages over metals, making them the material of choice when higher operating temperatures and / or lighter weight are required. [0003] CMC components are typic...
