Problems solved by technology

Such voids may require filler material and / or additional densification material to reduce or eliminate the voids, which may increase the manufacturing complexity, time and / or cost of the composite part
Additionally, such voids can reduce the integrity of the composite part, which can reduce part yield and increase part reject rates, as well as reduce on-wing time and unscheduled repair calls

Embodiment Construction

[0040]Reference will now be made in detail to present embodiments of the invention, one or more embodiments of which are illustrated in the accompanying drawings. Numeral and letter designations are used in the detailed description to refer to features in the drawings. The same or similar symbols are used in the drawings and description to refer to the same or similar parts of the present invention. As used in this specification, the terms "first", "second" and "third" are used interchangeably to distinguish one component from another and are not intended to indicate the position or importance of individual components. The terms "upstream" and "downstream" refer to relative directions with respect to fluid flow in a fluid path. For example, "upstream" refers to the direction in which fluid flows out, while "downstream" refers to the direction in which fluid flows.

[0041] Referring now to the drawings, wherein like numerals designate like elements throughout the several fig...

Abstract

Ply layups and methods for forming composite components are provided. For example, a method for forming a composite component comprises laying up a plurality of composite plies to form a composite plylayup; partially processing the composite ply layup to form a green state layup; machining the green state layup; assembling the green state layup with one or more sub-assemblies; and processing thegreen state layup and the one or more sub-assemblies to form the composite component. In an exemplary embodiment, the composite component is a turbine nozzle airfoil. Another exemplary method comprises laying up a plurality of composite plies to form a composite ply layup; compacting the composite ply layup to form a green state layup; machining the green state layup; assembling the green state layup with one or more sub-assemblies; and processing the green state layup and the one or more sub-assemblies to form the composite component.

Description

technical field [0001] The present invention generally relates to composite components. More specifically, the present invention relates to composite ply stacks and methods for shaping composite ply stacks. Background technique [0002] More commonly, non-traditional high temperature composite materials such as ceramic matrix composite (CMC) materials and polymer matrix composite (PMC) materials are being used in applications such as gas turbine engines. Components constructed from such materials have higher temperature capabilities than typical components, such as metal components, which may allow for improved component performance and / or increased engine temperatures. Composite components can also provide other advantages, such as improved strength-to-weight ratios. [0003] Typically, composite components are formed at least in part from a plurality of layers of composite material. Composite plies may be cut from composite matrix tapes or sheets, which may also include...
