In addition, the invention relates to a method for the production of a sandwich panel according to the invention.

A pressure bulkhead made of fiber composite material for an aircraft fuselage for the pressure-tight axial closure of a fuselage region configured to be put under internal pressure. The bulkhead comprises a first area element, at least one second area element and a plurality of core elements. The first area element has a plurality of receptacles. Each receptacle is configured to receive a core element. The core elements are received in the receptacles between surfaces facing one another of the first area element and of the at least one second area element. The surfaces facing one another of the first area element and of the at least one second area element are connected to one another in regions without core elements.

A method of fabricating a formed structure with expandable polymeric shell microspheres. A first plurality of polymeric shell microspheres are heated from an unexpanded state to an expanded state to form a plurality of expanded microspheres. The plurality of expanded microspheres are mixed with an epoxy resin and a second plurality of unexpanded polymeric shell microspheres. The mixture is formed in a shape to create a preform. The preform is wrapped with fiber tape to create a wrapped preform. The wrapped preform is placed in a mold. The mold is heated and the second plurality of unexpanded microspheres expand from an unexpanded state to an expanded state. The mold is cooled and the formed structure is removed from the mold.

Herein is described a non-metallic rim for a wheel, the rim comprising: a barrel having first and second flanges extending radially outward from opposing edges of the barrel, and the barrel comprising a first bead seat and a second bead seat arranged axially inwardly, respectively, of the first and second flanges, wherein a primary structural component extends at least through the first flange and the barrel, the primary structural component being capable of bearing the majority of the radial and/or lateral load that, in use, would be borne by the rim a protective insert is disposed between an outer face of the first flange and the primary structural component and/or at least a portion of the first bead seat is spaced apart from the primary structural component and the primary structural component, bead seat and, if present, the protective insert are bound by a polymer matrix.

In one particular embodiment, a method for making a fiber-reinforced, composite article having an internal passageway includes providing a layup tool, fiber placing a base layup onto the layup tool, and generating a groove in the base layup. The method further includes placing a mandrel in the groove, fiber placing a top layup onto the base layup and the mandrel, curing the base layup and the top layup, and removing the mandrel from the base layup and the top layup. In another particular embodiment, the mandrel is replaced with a non-removable tube.

Co-molding of non-crimped fabric and sheet molding composition. The pre-preg of non-crimped fabric is dried to achieve suitable stiffness for molding. The pre-preg allows the pre-formed non-crimped fabric feature to retain its shape during molding. A plurality of thorns is provided in the molding tooling to further prevent movement of pre-preg during molding. The method of co-molding includes, drying of the pre-preg to achieve suitable stiffness for molding, pre-forming of the pre-preg, and incorporating a plurality of stand-off features or thorns in the molding tool to prevent movement of pre-preg during co-molding so that predetermined full coverage of non-crimped fabric is maintained in predetermined area(s) of the molded part and the continuous fibers of the non-crimped fabric are not distorted.

A method for making a plural-component, composite-material, highway dowel-bar including (1) preparing an elongate core train possessing endo-abutting, longitudinally alternating, (a) elongate, high-shear-strength, cylindrical cores having a common cross section, and (b) elongate, but shorter, cylindrical, fibre-reinforced plastic-resin end-plug blanks having opposite ends, and each having a cross section matching the cross section of the cores, (2) using the core train as a longitudinally moving mandrel, pultrusion-forming a fibre-reinforced plastic-resin sleeve continuously and bondedly around the core train so as to produce a pultrusion-result, intermediate, dowel-bar product, and (3) following pultrusion-forming, cross-cutting the intermediate, dowel-bar product at each longitudinal location therein which is intermediate the opposite ends of the end-plug blanks, thereby to form completed dowel bars.

A reinforced hockey stick blade and a related method of manufacture are provided. The hockey stick blade can include a core element defining one or more longitudinal channels bounded by an upper core portion, a lower core portion, and a bridge portion interconnecting the upper and lower core portions. The hockey stick blade can additionally include a plurality of fiber-reinforced plies substantially encapsulating the core element and a reinforcing material received within the one or more longitudinal channels. The reinforcing material can extend longitudinally from a first channel end portion to a second channel end portion, and can include woven or unidirectional fiber-reinforced plies. The reinforcing material can additionally extend transversely across the channel to form a blade structure having increased blade strength and durability over existing composite hockey stick blades.

A modular fiber reinforced plastic flange for a structural composite beam which comprises a body formed of a plurality of elongate elements arranged in an array, wherein the dimensions of the body are substantially determined by the number and arrangement of the elongate elements in the array, and a skin member at least partially surrounding the array. Also, a structural composite beam comprising the modular fiber reinforced plastic flange and a shear web connected to the skin member of the modular flange. A method of making the modular flange and beams, and a kit of parts for making the modular flange are also disclosed.
