Disclosed herein is a molded laminated structure having negative draft angles and methods of manufacturing a molded laminated structure having negative draft angles. A preliminary structure having a first outer layer and a second outer layer is molded with a bend that divides the preliminary structure into two sections with an angle between the two sections of less than 180-degrees. Portions that extends from the sections are at positive draft angles. A groove is formed in the preliminary structure at the bend but not formed in a constant cross-section of the second outer layer. The preliminary structure is folding along the bend to at least partially close the groove and form a molded laminated structure with portions that extend at a negative draft configuration while retaining the second outer layer continuous throughout the molded laminated structure.

Methods produce a folded connection, sealed by means of an adhesive composition and by means of first and second sheetlike elements, wherein a flange of the first sheetlike element, having a first surface (11) and a second surface (12), is taken back over a flange of the second sheetlike element. The methods apply at least one layer of an adhesive composition to the flange of the first sheetlike element, bead the flange of the first sheetlike element around the flange of the second sheetlike element, and apply the adhesive composition to both the first and second surfaces of the flange of the first sheetlike element.

A folded core structure formed from an uncut flat body, has a plurality of consecutive 3D-structures and connecting areas each formed by plastic deformation, and includes first and second primary surfaces oriented plane-parallel to each other. The first and second primary surfaces include a first secondary surface extending over the entire width of the folded core structure and extending over a part of the length of the folded core structure. The first secondary surface is oriented parallel to the first primary surface, and the first secondary surface is located at a distance from the first primary surface between the first and second primary surfaces. A channel for fluid flow at least along the width of the folded core structure is provided. The first and/or second primary surface is/are configured to provide dimensional stability under a compression force applied perpendicular to the first primary surface of the folded core structure.

A structural component for a floor assembly of a vehicle. The structural component is formed integrally and includes at least one hinge element and a base part. The base part is configured to support the structural component on the vehicle when the structural component is installed in the vehicle. The at least one hinge element includes at least one flap element which is connected at least in regions to the base part and is configured to be pivoted relative to the base part and, in an end position, to at least partially enclose at least one predetermined construction space of the vehicle. The at least one flap element is furthermore configured in order, in the end position, to abut or to engage in a form-fitting manner against or on respective vehicle elements delimiting the at least one construction space of the vehicle.

A composite component adapted to be formed into an aerofoil, a method of forming an aerofoil, an aerofoil, an aircraft wing and a forming jig. The method involves forming a flat layup sheet of plies (1) to be folded about a central leading edge region (6) of the layup into an aerofoil shape, applying to the flat layup (1) one or more layups of plies (9, 10) shaped as spars, partially curing the layup (1) with the spars attached, folding the resulting partially cured composite component (30) about the leading edge region (6) in a forming jig (19) so that opposing edges (4, 5) of the sheet meet as a trailing edge (36) of the aerofoil (35), clamping the jig (19) closed, and curing the composite component (30) and adhesive in the forming jig (19) to form the finished aerofoil (35).

The invention is directed to a balanced process for extrusion of a plastic corrugated sheet or blanks, and subsequent converting of the blanks into plastic boxes. The process includes conveying the blanks to a plurality of forming stations for incrementally forming features on the blank needed for forming a box. The present process is performed at a slower speed than typical paper corrugated forming.
