Abstract: The invention relates to a stable one piece wheel, which is particularly suitable for cycles having an increased system weight such as electrically powered bicycles or cargo bikes, and a method producing said vehicle wheel. Said vehicle wheel comprises an annular portion (110), a plurality of spokes (120) and a hub portion (130) integrally formed by mould injection of fibre reinforced or carbo nano tubes containing thermoplastic, wherein each of the plurality of spokes (120) comprise a substantially Z-shaped cross section with a middle leg (122) and a pair of outer legs (121, 123), wherein the angle (?) enclosed by each of the pair of outer legs and the middle leg is greater than a right angle and wherein the length of the middle leg (122) increases from the annular portion (110) toward the hub portion (130).

Abstract: A stable, low-weight wheel which is particularly suitable for high system-weight bicycles, such as electrically powered bicycles and cargo bikes, includes a hub, at least three solid-body spokes disposed rotationally symmetrical to the wheel axis, and a rim. The body of the hub, spokes and rim is made in one piece by injection molding of a glass-fiber reinforced thermoplastic. The spokes have an S-shaped cross-section with an opening angle which increases in the direction of the rim, taper from the rim towards the hub in a central cross-section of the wheel, and taper from the hub towards the rim in a wheel cross-section running through the center of least one spoke. A method for producing the wheel is also provided.

Abstract: The invention relates to a multilayered, flexible, flat semi-finished product or component with a segment-like surface and a method for its manufacture, as well as a multidimensionally curved moulded part made therefrom and a method for the manufacture of such a component.

Abstract: The present invention relates to a method and to an apparatus for producing plastic products with an integrated reinforcing structure. To do so, a flexible fabric is first placed onto a surface of a cavity of a mold and is successively coated with plastic on the various sides.

Abstract: The present invention relates to a sandwich component, which comprises a honeycomb core (1) having a plurality of webs (1?) and at least one cover layer (2, 3), wherein the honeycomb core (1) is made of a cellulose-based material, in particular paper. The cover layer (2, 3) is formed from a fiber-reinforced semifinished product having a thermoplastic material matrix, wherein the webs (1?) of the honeycomb core (1) are partially received into the thermoplastic material matrix of the cover layer (2, 3) at connection points (A) to the cover layer (2, 3) so that the sandwich component is bonded. The invention further relates to production methods for the sandwich component.

Abstract: A casting machine system includes a first casting machine and a separate second casting machine, wherein the first casting machine is a metal-casting machine and the second casting machine is a plastic-casting machine, or the first casting machine is a plastic-casting machine and the second casting machine is a metal-casting machine. An associated process produces hybrid metal/plastic articles. The casting machine includes a transfer device for transferring a precursor product, produced by a first casting process in the first casting machine, to the second casting machine, in which a hybrid metal/plastic component is formed from the precursor product by a second casting process, and a temperature-regulating device for regulating the temperature of the precursor product in a controllable manner after its removal from the first casting machine, and before starting the second casting process.
