A sheet metal member forming method comprises placing a fiber bundle of a predetermined length, via a thermosetting resin, in a predetermined position on a surface of a sheet metal member, forming a coating film on at least a part of the sheet metal member after the placing of the fiber bundle, and while heating and drying the coating film, heat-curing the thermosetting resin to bond the fiber bundle to the sheet metal member.

In some examples, a technique including positioning supports such that the supports are between a first metallic substrate and a second metallic substrate, wherein an undulating member is located between the first metallic substrate and the second metallic substrate, the undulating member defining a plurality of first peaks adjacent to a first surface of the first metallic substrate and a plurality of second peaks adjacent to a second surface of the second metallic substrate, wherein a first support of the supports is positioned such that the first support extends between a first peak of the plurality of first peaks and the second surface of the second metallic substrate; welding the first peak to the first surface of the first metallic substrate in an area of the first support; and removing the first support by at least one of a thermal removal process or a chemical removal process.

A method for manufacturing a beam (P1, P2) with closed section, the beam being produced by combining a first profile (P10, P20) and a second profile (P11, P21), including the following steps: producing the first profile by a first stamping of a first plate (5, 50) between a first punch (1, 10) having a first imprint and a second punch (2, 20) having a second imprint and incorporating a core (3, 30) modifying its second imprint; holding the first profile (P10, P20) on the first punch and positioning the core (3, 30) above the first profile (P10, P20); producing the second profile (P11, P21) by a second stamping of a second plate (6, 60) against the core (3, 30) between the first punch (2, 20) and the assembly formed by the superposition of the first punch (1, 10), the first profile (P10, P20) and the core.

A vehicle floor panel is provided in which a honeycomb core made of metal sandwiched and adhered between two CFRP plates is one in which a large number of core units formed into a polygon shape are continuous within one plane so as to share a side of the polygon. Since closed-section parts formed by a hat-shaped cross section part formed along the side and one CFRP plate are continuous with each other at a vertex of the polygon of the adjacent core units, not only is it possible to lighten the weight by opening the interior of the polygon (P) shape core unit, but it is also possible to enhance the energy-absorbing performance by dispersing and transmitting a collision load inputted into one direction of the floor panel toward a plurality of other directions because the high strength load transmission path is continuous with other load transmission paths.

A manufacturing method is provided during which a plurality of first apertures are formed in a first plate to provide an apertured first plate. A plurality of second apertures are formed in a second plate to provide an apertured second plate. The apertured first plate and the apertured second plate are bonded to a base sheet to form a structure. The base sheet is bent to form a bend in the structure between the apertured first plate and the apertured second plate.

An exterior panel for hypersonic transport vehicles is formed of a superplastic metal alloy such as titanium for accommodating high thermal stresses of hypersonic flight. The exterior panel, designed as re-usable on such transport vehicles, includes an exterior skin configured for atmospheric exposure, and an interior skin configured for attachment to structural frame members of the transport vehicles. An intermediate skin is situated between a pair of multicellular cores; each multicellular core is sandwiched between the exterior and interior skins, one core being situated between the exterior and intermediate skins, while the other is situated between the intermediate and interior skins. An airflow channel (AFC) extends through at least one of the multicellular cores for cooling of the exterior panel. Each multicellular core is superplastic formed and diffusion bonded to the other, as well as to its respective pair of skins to form an exterior panel having a unified structure.

This invention concerns a method of joining metal sheets, comprising the following operating0 steps: a) providing a first metal sheet and a second metal sheet intended to be joined together in the vicinity of a first and a second straight edge, respectively; b) bending said first metal sheet parallel to said first edge so as to obtain a first edge flap; c) bending into a U- or V-shape a portion of said second metal sheet parallel to said second edge to obtain a longitudinal pocket in such a way that between said second edge and said pocket a second edge flap is defined; d) coupling said first metal sheet with said second metal sheet inserting said first flap inside said pocket; e) bending said pocket and the first flap inserted therein against said second flap so as to create an irreversible mechanical joint between the two metal sheets.

A method for manufacturing, transporting, and installing an extruded aluminum roof truss by manufacturing an extrusion that comprises a top chord extrusion, a bottom chord extrusion, a web brace extrusion, manufacturing standardized components such as a connector, a hinge, a bracket, and a fastener used to configure the extrusion into a truss configuration, pre-assembling the extrusion with an optionally pre-determined set of the standardized components required to either fully or partially assemble the truss prior to transport and installation at the building site, transporting the truss in either a fully or partially assembled compact configuration to the installation site, rotating the truss open by pivoting the web bracing into alignment with a matching connector hole on an extrusion at the installation site, and installing any required connectors or remaining standardized components to complete the truss.
