Abstract:
There is provided a laminated hybrid metallized polymer film for erosion protection of a composite structure. The laminated hybrid metallized polymer film includes a metal foil layer, a laminating adhesive layer underlying the metal foil layer, and a polymer film layer underlying the laminating adhesive layer. The polymer film layer is laminated to the metal foil layer with the laminating adhesive layer coupled between the metal foil layer and the polymer film layer. The laminated hybrid metallized polymer film further includes an adhesive layer underlying the polymer film layer. The adhesive layer adheres the polymer film layer to a substrate surface of the composite structure. The metal foil layer, the laminating adhesive layer, the polymer film layer, and the adhesive layer form the laminated hybrid metallized polymer film for application over and to the substrate surface of the composite structure.
Abstract:
Manufacturing a thermoplastic composite tubular structure embedded with a first load fitting comprising the steps of braiding a first plurality of inner layers of thermoplastic composite material around a soluble, expandable mandrel. A first load fitting is positioned on the first plurality of inner layers of thermoplastic composite material. A second plurality of outer layers of thermoplastic composite material is braided around the first load fitting and the mandrel so as to form an overbraided mandrel embedded with the first load fitting. The overbraided mandrel is installed into a matched tooling assembly and heated at a specified heating profile in order to consolidate the first plurality of inner layers of thermoplastic composite material and the second plurality of outer layers of thermoplastic composite material with the first load fitting so as to form a thermoplastic composite tubular structure embedded with the first load fitting. A second load fitting may be positioned on the first plurality of inner layers of thermoplastic composite material.
Abstract:
Provided are methods for cleaning processing tools from residue using laser ablation. Also provided are processing tools comprising non-metal base portions and protective optical layers that cover and shield these base portions from laser ablation. For example, a protective optical layer may reflect a laser beam used for ablating the tool. Methods of forming these protective optical layers on non-metal base portions are also provided. In some embodiments, this protective optical layer is the outermost layer exposed to the environment. Alternatively, the protective optical layer may be covered by a release layer. The release layer may be retained or removed during laser ablation. In some embodiments, light emitted by a processing tool during laser ablation is analyzed to determine performance of its protective optical layer. This feedback may be used to control the laser ablation such as to control orientation of the laser beam relative to the processing tool.
Abstract:
A shape memory structure includes a plurality of bases directly attached to a composite structure and arranged along a first line at a first edge of the composite structure. A plurality of buckle-shaped shape memory structures are attached to corresponding ones of the plurality of bases, such that first ends of the plurality of buckle-shaped shape memory structures are raised relative to the composite structure. Second ends of the plurality of buckle-shaped shape memory structures are directly attached to the composite structure along a second line at a second edge of the composite structure, the second edge being opposite the first edge. When activated, the shape memory structure changes from a buckled shape to an original shape to cause the composite structure to assume a deployed shape; when deactivated, the shape memory structure to resumes a buckled shape and the composite structure an undeployed shape.
Abstract:
Method and apparatus for controlling a shape of a composite structure. A shape memory structure associated with the composite structure is activated. The shape memory structure changes from a buckled shape to an original shape and causes the composite structure to change from an undeployed shape to a deployed shape. The shape memory structure is deactivated. The shape memory structure changes from the original shape to the buckled shape in response to a load from the composite structure and causes the composite structure to change from the deployed shape to the undeployed shape.
Abstract:
A hybrid coating composition including an organosilane component, a metal alkoxide component and a surfactant component, with the metal alkoxide component present in the composition at a molar ratio of about 75:1 with respect to the surfactant component. The hybrid coating composition once cured on a transparent substrate has an initial clarity greater than 98.
