The present disclosure provides fluid barriers as well as systems and methods of forming fluid barriers. The method includes cleaning, via a blast media, a first side of a component and heating the component to a first temperature. Subsequently, the component is cleaned using a solvent. Subsequent to heating at least the component, a primer coating layer is formed on the first side of the component, and a topcoat layer is formed in contact with the primer coating layer. A primer coating material can be heated to a second temperature prior to formation of the primer coating layer. The first temperature can be different than the second temperature.

Systems and methods of forming a fluid barrier

A blocker door assembly for use in a gas turbine includes a panel, a core integrally formed with the panel, and a plurality of mounting structures extending from at least one of the panel and the core. The plurality of mounting structures are integrally formed with the core and the panel such that the panel, the core, and the mounting structures are co-molded from a thermoplastic material.

A test coupon having node bonds is disclosed. In some aspects, the method includes a first foil and a second foil, stripes of adhesive serially disposed across a width of the first foil or the second foil and coupling the first foil and second foil to one another to form node bonds, and a first adherend coupled to the first foil and a second adherend coupled to the second foil such that the first foil and the second foil are provided between the first adherend and the second adherend, the first adherend and the second adherend being connectable to load blocks of a test apparatus capable of loading the test coupon to determine characteristics of each of the node bonds formed from the stripes of adhesive. A method for testing node bonds and a related apparatus are also disclosed.

A blocker door assembly for use in a gas turbine engine includes a facesheet including a plurality of openings to facilitate noise attenuation and a body portion coupled to the facesheet. The body portion includes a backsheet integrally formed with a honeycomb core, wherein the body portion is molded from a thermoplastic material.

A compression molding assembly for molding a honeycomb core, including a plurality of cells defined by a plurality of walls, of a blocker door is provided. The compression molding assembly includes a ram plate comprising a plurality of openings defined therethrough and a plurality of core inserts coupled to the ram plate such that the plurality of core inserts are configured to form the honeycomb core of the blocker door. Each core insert is removably coupled with a respective opening of the plurality of openings such that each core insert is configured to form a respective cell of the plurality of cells.

There is provided a system, a method, and a thermochromatic witness assembly to monitor a thermal environment of a composite structure. The thermochromatic witness assembly has a polymeric material and one or more thermochromatic probes mixed into the polymeric material to form a thermochromatic probe mixture. The thermochromatic probe mixture is applied to a transparent polymeric film, or is formed into the transparent polymeric film with a pressure sensitive adhesive (PSA) applied thereto, thus forming the thermochromatic witness assembly in a form of a thermochromatic applique. The thermochromatic applique is configured to be applied directly and continuously to a surface of the composite structure. The thermochromatic applique is further configured to monitor the thermal environment of the composite structure by detecting one or more temperatures and one or more times the surface of the composite structure is exposed to the thermal environment.
