A fastening insert made of plastic with a T-shaped configuration consisting of an insert disc and a hollow cylindrical shaft fastened to the insert disc. The insert disc has a plurality of passage openings arranged off-center, at least one of which has an edge projection extending circumferentially continuously or circumferentially in sections, which is formed as toothing and extends on one side or both sides beyond the respective fastening side of the insert disc. This toothing ensures an additional form-fit connection or fixation of the fastening insert in a preferably fiber-reinforced composite material.

A housing for an electronic device is disclosed. The housing comprises a first component and a second component separated from the first component by a gap. The housing also includes a first molded element disposed at least partially within the gap and defining at least a portion of an interlock feature, and a second molded element disposed at least partially within the gap and mechanically engaging the interlock feature. The first component, the second component, and the second molded element form a portion of an exterior surface of the housing. A method of forming the housing is also disclosed.

A method of forming a joint between a composite component and a metallic component is disclosed. The method includes forming a first groove in an outer surface of the metallic component on a first end of the metallic component. The first groove extends circumferentially on the outer surface relative to a center axis of the metallic component, and the first groove extends radially inward from the outer surface relative the center axis. The method further includes inserting the first end of the metallic component into a first end of the composite component. A second groove on the composite component over the first groove of the metallic component such that the composite component extends radially inward into the first groove of the metallic component. A composite hoop reinforcement is then applied in the second groove in a circumferential direction and the composite component, and the composite hoop reinforcement are solidified.

A gearwheel pair for a gear unit, comprising a first gear and a second gear, which can be meshed with one another, wherein the first gear consists entirely or partially of metal or plastic and the second spur gear comprises an outer part having a gear rim made of a first plastic and having a number of injection-molded portions, an inlay part made of metal, and a connecting part, which is arranged between the inlay part and the outer part and is made of a second plastic for the interlocked and/or materially-bonded connection of the inlay part and the outer part and further relates to the second spur gear per se, a gear unit having such a gearwheel pair, and a method for producing a second gear, which is used for such a gear unit.

The invention relates to a device comprising: a first layer (11) of a thermoformable material that is inelastically deformable in a thermoforming temperature range, a second layer (1) of a viscoelastic material that is elastically deformable in a temperature range including a use temperature range of the device and the thermoforming temperature range, and wherein: the use temperature range is lower than the thermoforming temperature range, the first layer is bonded to the second layer, the thermoformable material is elastically deformable and more rigid than the viscoelastic material in the use temperature range, the thermoformable material is less rigid than the viscoelastic material in the thermoforming temperature range.

Disclosed are reinforced structures. The structures are comprised of reinforced elements that have continuous fibers embedded in a matrix material. The reinforced elements are combined in a matrix material to form a desired shape of reinforced structure.

A mechanical interlock pin assembly includes a shaft having a first end and a second end. The mechanical interlock pin assembly includes a set of helical spline elements disposed at the first end of the shaft, the set of helical spline elements extending along a longitudinal axis of the shaft. The mechanical interlock pin assembly includes a bearing rotatably coupled to the second end of the shaft, the bearing configured to allow rotation of the shaft between a first rotational position and a second rotational position relative to a mold cavity.
