Abstract: The invention relates to a composite panel, including: a plurality of individual composite panels, each having at least one core and two surface skins and each being assembled along an assembly zone with at least one neighbouring individual panel by one of its sides, a reinforcement zone formed in the surface skins on either side of the assembly zone and along this zone, a strip of reinforcing material positioned over said assembly zone of a panel with the neighbouring panel or panels, in each reinforcing zone.

Abstract: A reinforced, thermoplastic, injection molded cellular core is provided, wherein the cellular core can include minimum wall thickness sections of less than 1.5 mm and in selected constructions less than 0.5 mm, wherein larger reinforcing pillars at disposed at predetermined locations to form a structural body. A cross sectional shape, sizing and spacing of a plurality of cells within the cellular core can be set in a predetermined configuration to provide for varying density of the cellular core. Reinforcing elements can be uniformly or non-uniformly distributed throughout the cellular core. Stratum can be integrally formed with the cellular core to provide additional performance characteristics.

Abstract: A honeycomb structure (1) comprises a plurality of small tubes (2) bonded to each other along their sides. The small tubes (2) have a base body (4) made of a thermoplastic and which, at least on the outside, preferably on the outside and on the inside, carries a coating (5) made of an adhesively-active thermoplastic material. As a result of this coating (5), a good bonding of the small honeycomb tubes (2) to each other as well as to a cover layer (3) is possible.
