Abstract: A composite panel (20), which comprises multiple rows of cores (40) and sheets (60). The core rows (40) extend co-directionally along a first direction (X) and are arranged in an array along a second direction (Y). Each sheet row (60) is formed by a sequence of sheets (62) that extend in line along the first direction, and is arranged in-between two adjacent core rows along the second direction. The sheets are folded into U-shapes or Z-shapes around respective adjacent cores, and the sheets within the same sheet row (60) have leading and trailing edges (70, 72) that abut against or overlap with directly preceding sheets of the same sheet row.

Abstract: A panel (20) having opposite surfaces (22, 24), and including sheets (42, 43) and elongated cores or voids (40). The cores/voids extend parallel along a first direction (X), are arranged mutually adjacent in a second direction (Y), and include an outermost core/void (40a) along a panel edge (26). Each sheet includes a medial portion (44, 45) between two adjacent cores/voids, a first lateral portion (46, 47) folded away from the medial portion over one adjacent core/void, and towards the second direction along the first surface, and a second lateral portion (48, 49) folded away from the medial portion over another adjacent core/void, and towards a negative second direction (?Y) along the second surface. The sheets include an enveloping sheet (43), the first lateral portion (47) thereof extending into a folded lateral region (50, 52) that at the panel edge is folded around the outermost core/void, and extends in the negative second direction back towards the second surface.

Abstract: A blade made of layered material, such as composite material, configured for exposure to a fluid flow, comprises skins (1, 2) defined between a leading edge (3) and a trailing edge (4) which skins in cross-section form a flow profile. The layered material may consist of several layers of fiber material (5, 5?, . . . ) impregnated with a matrix material, wherein layers of fiber material each comprise a respective body portion (6, 6?, . . . , 13) between and transverse to the skins and each at least a respective skin portion (7, 7?, . . . ; 8, 8?, . . . ) that forms part of the skins. The said skin portions all extend from the related body portion in the direction of the trailing edge. Of said skin portions at least two consecutive skin portions of the one skin overlap and/or two consecutive skin portions of the other skin overlap each other.

Abstract: Disclosed is a method for producing a profiled semi-finished plastic product from flexible web material, including: providing a plurality of webs of flexible material, —continuously and simultaneously feeding the webs of material to and along a plurality of shaping pieces arranged next to each other, folding each web of material around a respective shaping piece to form a body and an edge strip which projects transversely with respect to the body,—causing the edge strips of different webs of material to at least partly cover each other, impregnating the webs of flexible material provided or the assembly of webs of material with folded-over edge strips covering each other with a hardenable unit, causing the hardenable unit to harden to form the profiled semi-finished plastic product, wherein open spaces remain between two neighbouring bodies and edge strips.

Abstract: A core element is provided, having the shape of a block with a first surface, a second surface situated opposite the first surface, mutually facing longitudinal side faces, and mutually facing transverse side faces. The first surface is provided with the first groove that is a continuous groove which extends parallel to the longitudinal side faces. The longitudinal side faces are provided with the side wall grooves, the side wall grooves being continuous side wall grooves which extend between the first surface and the second surface and are separated from the first groove in the first surface.

Abstract: A bridge construction having a bridge support or abutment and a bridge deck supported thereon. The bridge deck includes a composite panel with a top plastic skin, a bottom plastic skin and a core arranged between and attached to the plastic skins. The bridge deck also includes an edge beam extending along at least one edge of the composite panel and resting on the bridge support. The top plastic skin has a protruding part which protrudes laterally relative to the core and the bottom plastic skin. The protruding part of the top plastic skin extends over and is attached to a top side of the edge beam, and both the core and the lower plastic skin extend laterally up to a front side of the edge beam.

Abstract: A method for producing a panel includes steps of providing a core element, covering the core element with a strip of impregnable flexible material that continues beyond the core element, providing a following core element alongside the preceding covered core element on that portion of the strip of flexible material that extends beyond the preceding core element, covering the following core element with a following strip of flexible material that extends beyond the following core element, and repeating each of those steps at least once. The method further includes impregnating the strips of material with a hardenable fluid, and hardening the impregnated strips. Each following strip of flexible material is fitted over the top face of a following core element, as well as over the preceding strip of flexible material extending over the top face of a preceding core element.

Abstract: A bridge construction comprises a bridge support or abutment (2) and a bridge deck (1) supported thereon, comprising a composite panel (5) with a top plastic skin (6), a bottom plastic skin (8) and a core (7) between and attached to the plastic skins. The bridge deck also comprises an edge beam (9) on at least one edge of the composite panel and resting on the bridge support. The edge beam (9) overlaps the core (7) of the composite panel (5) in the height direction, while the top plastic skin (6) has a protruding part (28) which protrudes relative to the core (7). The protruding part (28) of the top plastic skin (6) extends over and is attached to the edge beam (9).

Abstract: A method of producing a panel includes: placing an assembly including core elements and impregnatable material webs extending along and between the core elements on a mold, which assembly includes a first side and a second side which is situated opposite the first side, enclosing the assembly under a cover layer in a sealing manner with respect to the mold, introducing at least one inlet for injection material, which inlet ends at a first side of the assembly, connecting the space which is enclosed by the cover layer and the mold to a discharge, injecting injection material via the inlet on the first side of the assembly and causing the injection material to move along via paths formed by the material webs between the core elements, discharging air and/or gas from the enclosed space via the discharge via underpressure at a position which is at a different level to the position where the inlet ends.
