Abstract: The present invention relates to a molding which comprises a foam and at least one fiber (F). The fiber (F) has a first part (FT1), a second part (FT2) and a third part (FT3). The third part (FT3) of the fiber (F) connects the first part (FT1) and the second part (FT2) of the fiber (F) and is arranged on a second side of the foam. A first region (FB11) of the first part (FT1) of the fiber (F) and a first region (FB12) of the second part (FT2) of the fiber (F) are located inside the molding and are not in contact. A second region (FB21) of the first part (FT1) of the fiber (F) and a second region (FB22) of the second part (FT2) of the fiber (F) project from a first side of the foam. The present invention further relates to a process for producing the moldings according to the invention and to a panel which comprises the molding according to the invention and at least one layer (S1) and also to a process for producing the panel. The present invention further relates to the use of the molding/of the panel, for example as a rotor blade in wind turbines.

Abstract: The present invention relates to a process for converting moldings. Here, a molding comprising a foam and at least one fiber (F), wherein the fiber (F) is with a fiber region (FB2) located inside the molding is at least partially divided at least once, wherein at least one fiber (F) is completely divided. The invention further relates to the thus obtainable converted molding and to a panel comprising the converted molding and at least one layer (S1). The present invention further relates to a process for producing the panel and to the use of the converted molding/the panel according to the invention as a rotor blade in wind turbines for example.

Abstract: The present invention relates to a molding made of reactive foam, wherein at least one fiber (F) is arranged partially inside the molding, i.e. is surrounded by the reactive foam. The two ends of the respective fiber (F) not surrounded by the reactive foam thus each project from one side of the corresponding molding. The reactive foam is produced by a double belt foaming process or a block foaming process. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings according to the invention from reactive foam/the panels according to the invention and also provides for the use thereof as a rotor blade in wind turbines for example.
