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 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: Described herein is a process for producing polyurethane foams having a density of 30 g/dm3 to 70 g/dm3, in which (a) aromatic polyisocyanate is mixed with (b) polymeric compounds having isocyanate-reactive groups, (c) optionally chain extender and/or crosslinking agent, (d) catalyst, (e) blowing agent including water, (f) 0.1% to 5% by weight of lactam, and (g) optionally additives, at an isocyanate index of 50 to 95 to form a reaction mixture, and the reaction mixture is converted to the polyurethane foam, wherein the catalyst includes metal catalyst and amine catalyst, and the amine catalyst has tertiary nitrogen atoms and the content of tertiary nitrogen atoms in the amine catalyst is from 0.0001 to 0.003 mol/100 g of foam. Also described herein is a polyurethane foam and a method of using such a flexible polyurethane foam for the production of cushions, seat cushions, or mattresses.
