A method of adhering a first structure to a second structure using a primer, containing a primer fugitive inhibitor, and a film adhesive by removing the primer fugitive inhibitor under vacuum at room temperature conditions.

Method for adhering structures using silicone adhesive system

A surface mounted heater assembly for an aerospace component having a support layer, an electrically resistive heater foil element supported by the support layer, a coating covering the heater element; and an adhesive to secure said support layer to the component is provided. The coating has two layers that are visually distinct to permit identification of potential exposure of the heater foil element. A surface mounted heater having a multiple layer assembly having a support layer; a heater element and a transition layer to couple the support layer to the aerospace component is provided.

Surface mounted flexible heater for gas turbine engine application

An electrothermal heater assembly, configured to be embedded inside a component for anti-icing and/or deicing the component, includes a titanium foil configured for use as a heating element, at least one reinforcement layer adjacent the titanium foil, and an adhesive configured to bond the titanium foil to the at least one reinforcement layer. The heater assembly is configured such that the titanium foil carries a structural load within the heater assembly.

Titanium foil as a structural heater element

An installation method makes use of a tool that includes a block and a plate. The block is configured to align the installation tool with a U-shaped component. The plate extends from the block and is configured to hold a flexible component, such that the flexible component is accurately located within the U-shaped component.

Method of installing a flexible component in a U-shaped component

A system and process is disclosed for binding particles to a carrier material in an isolated relationship for use in composite fabrication. A slurry comprising particles dispersed in fluid is created in particle suspension tanks, deposited as a uniform layer and filtered using reduced pressure applied to a filter belt to leave behind isolated particles, the reduced pressure further acting to overcome electrostatic and other forces of attraction between the particles until they can be permanently bound to the carrier with a binder or adhesive and collected on a take-up roll.

Process and system for distributing particles for incorporation within a composite structure

A porous composite substrate that includes reinforcement material disposed within a resin matrix. The resin matrix includes a first matrix region with a first density, and a second matrix region with a second density that is different than the first density. The first matrix region includes a plurality of pores that are formed by pore forming material.

Composite substrates with predetermined porosities

A method of removably securing a reusable component to a replaceable component with a bonding agent is provided. The method includes, but is not limited to, preparing a first surface of the reusable component so that a bonding energy between the first surface and the bonding agent has a first level, preparing a second surface of the replaceable component so that a bonding energy between the second surface and the bonding agent has a second level, the second level being greater than the first level, and applying the bonding agent so that the bonding agent bonds the first and second surfaces to one another.

Methods and systems for removably securing reusable parts to replaceable parts

An apparatus for thermal mechanical machining of composite materials includes a head, a drive, and a shaft. The head has an abrasive face. The drive is coupled to the apparatus to move the head to produce abrasion of the composite material by the abrasive face. The shaft includes a passageway that communicates a heated gas to an interface between the abrasive face and the composite material. The gas removes particles that result from the abrasion of the composite material by the abrasive face. The gas can be heated sufficiently to carbonize or vaporize organic constituents of the composite material.

Thermal mechanical skive for composite machining

A connector for incorporation into a heater system for inlet struts includes a body having a tapered forward end and an opposite rear end. A plurality of forward electrical terminals are formed on the outer surface of the tapered end. A plurality of rearward electrical terminals are formed on the rear end of the body. The rearward electrical terminals are in electrical connection with the forward electrical terminals. The forward electrical terminals on the tapered end are in electrical contact with a plurality of electrical contacts connected to heating elements formed in a heating mat. The heating mat entirely envelops the connector. The heater mat is formed within a substantially rigid outer shell.

Connector for heater

A fixture includes a housing assembly defined along an axis. A pressure bar assembly is mounted to the housing assembly for movement relative the axis. A bladder assembly is mounted at least partially within the housing assembly such that pressurization of the bladder assembly is operable to exert a force on a workpiece along the axis with the pressure bar assembly.

Fluid pressure operated fixture

The present invention relates to a pressure application device for curing an adhesive on a component, particularly components of complex geometries. The device comprises a pair of jaws, at least one spring recessed into a cavity defined within the first jaw, and a cap. A first end of a spring partially extends into the cavity and a second end of the spring contacts the cap. When force is applied to the cap, the cap transmits the force through the spring to the first jaw. In order to limit the separation of the cap from the first jaw, a retainer is used.

Modular component pressure application fixture

An electrical connection for a heater for aerospace components having a titanium containing heater element; a copper containing conductor; and a welded or strong mechanical interface transition connecting the titanium containing heater element and the copper containing conduction transition. The transition has a titanium containing component and a copper containing component, where the titanium containing component is joined to the titanium containing heater element. A heater connection for a surface mounted heater for a jet turbine application having a titanium containing heater element, a copper containing conduction transition, and a weld transition connecting the heater element and the copper containing conduction transition. The weld transition has a titanium containing weld.
