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: Composite article comprising at least two layers of component a) and at least one layer of component b). The layers and are alternately linked together. Component a) has a compressive modulus of at least 10 MPa in contrast to the component b), which has a compression stress value at a compression of 40% of not more than 20 kPa. Composite articles are semi-flexible materials due to alternating rigid and flexible segments within the articles. Articles optionally contain at least one additional layer of component b), which layer is also alternately linked together with the respective layers of component a). At least one layer crosses at least one layer with an angle α in the range of 0°
