A crank arm for a bicycle may include a body extending along a body axis and having a first body end and a second body end axially spaced apart from the first body end. The insert may also include an insert provided toward the first body end. The insert may include a base portion having a radially outer surface. At least one extension may extend outwardly from the radially outer surface and may be encased within a corresponding recess in the body whereby relative planar movement between the body and the at least one extension in a first plane. The retaining portion may have a retaining portion width measured in the first direction and the retaining width may be greater than the throat width thereby inhibiting relative radial movement between the at least one extension and the recess and preventing radial extraction of the extension from the corresponding recess.

A fitting for connecting first and second components arranged at right angles to each other that includes a flange part, which extends in a first direction and has a first connection surface in contact with the first component, and which has at least one first connection hole formed by a bore of a first insert; and a base part, which extends in a second direction, perpendicular to the first direction, and has a second connection surface in contact with the second component, and which has at least one second connection hole formed by a bore of a second insert. The first insert is joined to the second insert by at least one loop of continuous fiber tow wound around radially outer surfaces of the first insert second inserts.

A device for producing a curved fiber preform from a bi- or multidirectional fiber semi-finished product, in particular for an aircraft or spacecraft fuselage component has first lamellae and second lamellae formed to be couplable to one another criss-cross such that they are positioned on a shared plane and thus form a grid. The lamellae at least in part are formed resiliently bendable about an axis intersecting the shared plane such that a local orientation of the lamellae in the grid changes. An adhesion device or structure is formed for temporarily adhering the fiber semi-finished product and is configured such that the local fiber orientation of the fiber semi-finished product also changes accordingly when the lamellae bend.

A method produces a cable. A sheath is applied to a product in strand form and the product in strand form is supplied, for this purpose, to an apparatus which has a bath containing a curable material. A build-up zone is formed in the bath, within which build-up zone the curable material is at least partially cured by an exposure source and through which the product in strand form is conveyed lengthwise in a conveying direction, so that cured material is arranged on the product in strand form and is conveyed out of the bath together with the product in strand form as a sheath on the product in strand form.

Provided is a method of manufacturing at least a portion of rotor blade for a wind turbine, the method including: casting at least a portion of an rotor blade outer surface using a casting material thereby at least partially embedding at least one fluid convey tube into the casting material, the fluid convey tube being provided for conveying fluid into or out of a deformable container for adjusting an adjustable flow regulating device of the rotor blade.

A hollow roto-moulded article, having an inner wall defining an interior of the article and integrally formed structure with the inner wall, the integrally formed structure protruding away from the interior of the article, the article formed of a first layer including one or more thermoplastic polymers, and a second layer including one or more fibrous materials.

A prepreg laminate is described that is a fiber-reinforced plastic material having high rigidity, lightweight properties and excellent moldability, where the prepreg laminate is obtained by a prepreg (A), in which non-continuous reinforcing fibers are impregnated with a thermosetting resin or thermoplastic resin, and a prepreg (B), in which non-continuous reinforcing fibers are impregnated with a thermoplastic resin, being laminated adjacent to each other, and by the prepreg (A) being disposed on at least one surface, at least some combinations of the prepreg (A) and the prepreg (B) adjacent to each other forming an overlap region that satisfies at least one of the requirements (1) and (2) as defined.
