Abstract: The present invention relates to a process for producing a molding made from blowing agent-containing foam comprising at least one fiber (F), wherein the at least one fiber (F) is partially introduced into the blowing agent-containing foam. The two ends of the respective fiber (F) that are not surrounded by the blowing agent-containing foam thus project from one side of the corresponding molding. The present invention also provides the molding as such. The present invention further provides a panel comprising at least one such molding, produced by the process according to the invention, and at least one further layer (S1). The present invention also provides for the production of the panels of the invention and for the use thereof, for example as a rotor blade in wind turbines.

Abstract: The present invention relates to a method for assembling moulded bodies. The invention also relates to a moulded body which comprises a foam and at least one fibre (F), the fibre (F) is within a fibre range (FB2) inside the moulded body and is at least once at least partially divided, wherein at least one fibre (F) is completely divided. The invention further relates to the thus obtained assembled moulded body, and to a panel with contains the assembled moulded body and at least one layer (S1). The invention further relates to a method for producing the panel and to the use of the assembled moulded body and the claimed panel, for example, as a rotor blade in wind turbines.

Abstract: The present invention relates to a process for the production of at least two-layer thermoplastic foam sheets via thermal welding of at least two thinner thermoplastic foam sheets. In the process of the invention, at least two heating elements are conducted on mutually offset planes between the surfaces to be welded of the thinner thermoplastic foam sheets, and the foam sheets here do not touch the heating elements. The number of layers of the thermoplastic foam sheet is per se a result of the number of thinner thermoplastic foam sheets that are thermally welded to one another. If by way of example three thinner thermoplastic foam sheets are thermally welded to one another, a three-layer thermoplastic foam sheet is per se obtained, and if there are four thinner thermoplastic foam sheets the result is accordingly per se a four-layer thermoplastic foam sheet.

Abstract: The present invention relates to a molding made of foam, wherein at least one fiber (F) is located partly within the molding, i.e. is surrounded by the foam. The two ends of the respective fiber (F) not surrounded by the foam thus each project from one side of the molding. The foam is produced by polymerization of a reactive mixture (rM) comprising at least one compound having isocyanate-reactive groups, at least one blowing agent and at least one polyisocyanate.

Abstract: The invention relates to a process for the production of at least two-layer thermoplastic sheets via thermal welding of at least one thinner thermoplastic sheet with density (D1) and of at least one second thinner thermoplastic sheet with density (D2), where the density (D1) of the first thinner thermoplastic sheet is smaller than the density (D2) of the second thinner thermoplastic sheet. The process introduces at least one first heating element and at least one second heating element along mutually offset planes between the two thinner thermoplastic sheets, where the surfaces of the thinner thermoplastic sheets do not touch the surfaces of the heating elements. The first heating element transfers a quantity of energy (E1) to the surface of the first thinner thermoplastic sheet, and the second heating element transfers a quantity of energy (E2) to the surface of the second thinner thermoplastic sheet, where the quantity of energy (E1) is smaller than the quantity of energy (E2).
