20170355152 · 2017-12-14 · ·

A method for integrating a backing-structure assembly in a structure of an aircraft or spacecraft is described. In this case, a plurality of individual elements is joined to form the backing-structure assembly. The individual elements for the backing-structure assembly and a skin portion for the structure are provided. The elements are arranged on a pre-assembly device which comprises retaining devices, which are each configured to hold one of the elements so as to be adjustable with respect to the position and/or location thereof. Some or all of the elements are connected to the skin portion. In the method, by adjusting the retaining devices for tolerance compensation, gaps between joint regions of the elements and the skin portion are eliminated or adjusted.

20170348919 · 2017-12-07 ·

Systems and methods are provided for utilizing support tools for forming laminates. One embodiment is a system that includes a pair of dies that hold a multi-layer laminate over a gap, a male die that presses the laminate into the gap causing the laminate to change shape, and a support tool inserted into the gap beneath the laminate. The support tool includes a base that extends in a lengthwise direction, struts fixedly attached to the base that project upward from the base and are distributed along the lengthwise direction, and a cap that is slidably attached to the struts, and that covers the struts to form an upper surface of the support tool. Each of the struts rises from the base to the cap.

Composite material structure forming method

A composite material structure forming method capable of improving the shape and dimensional accuracy inside a composite material structure. The method includes: winding a prepreg (2) around an inner jig (6); stacking a ply (8) on the prepreg (2) wound around the inner jig (6); and forming a composite material structure by providing composite outer plates (4a, 4b) on an outer periphery of the inner jig (6) on which the ply (8) is stacked and mounting divided outer jigs (9) thereon.

BEADED PANELS AND SYSTEMS AND METHODS FOR FORMING BEADED PANELS

A beaded panel includes a base panel and a beaded panel doubler made of a first fiber-reinforced thermoplastic composite. The beaded panel doubler is joined to the base panel to supplement a stiffness of the base panel.

Method of Designing and Producing Carbon Fiber Composite Wrist Pins
20230173769 · 2023-06-08 · ·

A method is provided of designing and producing a carbon fiber composite wrist pin using a combination of a carbon fiber composite pultruded rod that is overwrapped with a carbon fiber prepreg fabric. The use of the carbon fiber pultruded rod and the carbon fiber prepreg fabric results in a rod with optimal flexural strength properties to endure the flexural stress placed on a wrist pin during the cycling of an internal combustion engine. In addition, the overwrapping of the pultruded rod with a carbon fiber prepreg fabric allows for one pultruded rod blank to produce multiple wrist pin sizes by allowing one to change the outer diameter of the wrist pin by changing the thickness of the carbon fiber prepreg fabric overwrapping. After overwrapping, the rod blank is cut to a chosen specific length, optionally inserted into a metal sleeve, and coated with a thermal barrier coating. The wrist pin is then ground to a chosen specific tolerance and coated with an anti-friction coating.

METHOD FOR PRODUCING A HYBRID-STRUCTURE PART OF A MOTOR VEHICLE AND CORRESPONDING HYBRID-STRUCTURE PART

The invention concerns a method for producing a hybrid-structure part of a motor vehicle, comprising shaping of a sheet of metallic material, the provision of a sheet of composite material, application of a layer of connecting material on a face of said metallic material sheet or on a face of said composite material sheet, the shaping of a hybrid element by shaping said composite material sheet to the shape of said metallic material sheet and joining the composite material sheet to the metallic material sheet by means of said connecting material layer, and the production of ngidification elements by overmoulding using a polymer material.
