Embodiment Construction

[0033] Exemplary plies, methods for making the plies, and methods for making articles from the plies are provided. Embodiments of the present disclosure provide more cost-effective and time-efficient methods and products for making plies and articles formed from plies than methods and products that do not utilize one or more of the features disclosed herein. and provides the ability for directionalization of nonwoven fibers to follow a preset fiber routing line in the interior of the ply at any point.

[0034] refer to figure 1 , ply 100 includes a near net shape 102 and a ceramic matrix composite (CMC) nonwoven material 104 . The near-net shape 102 is a predetermined layer 108 of the article. The predetermined layer 108 may be any suitable topological construct, including but not limited to, a cross-sectional layer of an article, a curved layer of an article, an angled layer of an article, or a combination thereof, wherein the predetermined layer 108 is suitable for Form p...

Abstract

A method for manufacturing a ply (100) is disclosed. The method includes printing the ply, the ply including a near net shape (102) and a ceramic matrix composite nonwoven material (104). A ply (108) is disclosed wherein the near net shape is a predetermined layer of an article. A method for manufacturing an article is also disclosed. The method includes printing a first ply (200) and a second ply (206). The first ply (200) includes a first near net shape (202) and a first ceramic matrix composite nonwoven material (204), and the second ply (206) includes a second near net shape (208) and a second ceramic matrix composite nonwoven material (208). The method further includes applying the second ply (206) to the first ply (200), and consolidating the first ply and the second ply (206).

Description

technical field [0001] The present invention relates to plies, a method for making plies and a method for making articles from plies. More particularly the present invention relates to plies, methods for making plies and methods for forming plies comprising near net shape (sometimes referred to as near net shape) and ceramic matrix composite (ceramic matrix composite (sometimes referred to as ceramic matrix) (mass) composite material) A method of making an article from layers of nonwoven (nonwoven, sometimes called nonwoven) materials. Background technique [0002] Gas turbines are continually being modified to provide increased efficiency and performance. These modifications include the ability to operate at higher temperatures and harsher conditions, which often require material modifications and / or cladding to protect components from such temperatures and conditions. Additional challenges were realized when more modifications were introduced. [0003] One modification ...
