A method and apparatus for applying a sealant material. A nozzle system may be positioned relative to a structure using a robotic device. The sealant material may be applied in a number of streams onto a structure using the nozzle system and the robotic device to form a sealant deposit having a desired shape in which the sealant material has a viscosity greater than a selected threshold.

High-viscosity sealant application system

A method of forming a fastener includes inserting a blank precursor into a bore of a forming die having an enlarged bore portion, applying a first axial compression force to the blank precursor, and forming a cold-worked head section and an enlarged shank portion on the blank precursor corresponding to the enlarged bore portion. The enlarged shank portion has a nominal shank portion extending therefrom. The method additionally includes inserting the nominal shank portion into a bore of a final reduction die, applying a second axial compression force to the enlarged shank portion, and urging the enlarged shank portion into the bore of the final reduction die. The method includes reducing a cross-sectional area of the enlarged shank portion by approximately 2 to 5 percent to form a cold-worked shank section.

Method of forming a highly-deformable titanium or titanium-alloy one-piece fastener

A method of forming a fastener may include inserting a blank precursor into a bore of a forming die having an enlarged bore portion. The method may further include applying a first axial compression force to the blank precursor, and forming a cold-worked head section and an enlarged shank portion on the blank precursor corresponding to the enlarged bore portion. The enlarged shank portion may have a nominal shank portion extending therefrom. The method may additionally include inserting the nominal shank portion into a bore of a final reduction die, applying a second axial compression force to the enlarged shank portion, and urging the enlarged shank portion into the bore of the final reduction die. The method may also include reducing a cross-sectional area of the enlarged shank portion by approximately 2 to 5 percent to form a cold-worked shank section.

Method of assembling a structure using highly-deformable titanium and titanium-alloy one-piece fasteners

A method of improving the material properties of a composite by electrodepositing particular polymers, organic compounds or inorganic compounds onto electrically conductive fibrous substrates, whether individual fibers or as a fabric, to form composites of improved structural properties and having particular physical properties such as being ice phobic, fire resistant, or electrically conductive.

Electrochemical deposition process for composite structures

A high-strength, pre-coated, titanium or titanium-alloy material component is provided that includes a titanium or titanium-alloy material article having ultra-fine, submicron grain size microstructure and an organic coating of phenolic resin applied to the surface of the article. The article is prepared from a coarse grain titanium or titanium-alloy powder material that is cryomilled into an ultra-fine, submicron grain material, degassed, and densified. The densified material is formed or otherwise processed into a article, and pre-coated with an organic coating containing phenolic resin prior to installation or assembly.

Pre-coated, ultra-fine, submicron grain titanium and titanium-alloy components

A method and apparatus for attaching parts. A composite male fastening component is placed through at least a first part and a second part. The composite male fastener component preferably has a threaded portion. A composite female fastener component is positioned adjacent to and surrounding the threaded portion of the male fastener component. A portion of the composite female fastener component is caused to flow around and form into the threaded portion of the composite male fastener component. The portion of the composite female fastener component that flowed around and formed into the threaded portion of the composite male fastener component is re-solidified and re-consolidated such that the composite female fastener component is securely attached to the composite male fastener component thereby joining the mating parts.

Method and apparatus for fastening components using a composite two-piece fastening system

Method and apparatus for mechanically-joining components to assemble a composite structure. A first component and a second component may be provided. At least one of the first and second components may comprise a composite component. A hole may be formed in each of the first and second components. A metallic sleeve may be placed in the holes in the first and second components such that the metallic sleeve is in contact with the first and second components, and a composite rivet may be placed in the metallic sleeve. Heat and a deforming force may be applied to the composite rivet to join the first and second components to form an assembled composite structure.

Method and apparatus for assembling composite structures

The invention is a high-strength, pre-coated, aluminum or aluminum-alloy component comprising an aluminum or aluminum-alloy article having ultra-fine, submicron grain microstructure and an organic coating of phenolic resin applied to the surface of the article. The article is prepared from a coarse grain aluminum or aluminum-alloy material that is cryomilled into an ultra-fine, submicron grain material, degassed, and densified. The densified material is formed into an article, and coated with an organic coating containing phenolic resin prior to installation or assembly.
