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 process for producing a fiber-foam composite (FSV1), wherein a first fiber material (FM1) is applied to a first foam body (SK1) to give a first structured fiber surface (FO1) to which a second foam body (SK2) is subsequently applied to give the fiber-foam composite (FSV1).

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 ? in the range of 0°<?<180°, wherein both layers and are made of component b). Also, a method for producing those composite articles and the use of those composite articles in composite applications.

Abstract: The invention relates to a molding composed of extruded foam, wherein at least one fiber (F) is present with a fiber region (FB2) within the molding and is surrounded by the extruded foam, while a fiber region (FB1) of the fiber (F) projects from a first side of the molding and a fiber region (FB3) of the fiber (F) projects from a second side of the molding, and the extruded foam is produced by an extrusion process comprising the following steps: I) providing a polymer melt in an extruder, II) introducing at least one blowing agent into the polymer melt provided in step I) to obtain a foamable polymer melt, III) extruding the foamable polymer melt obtained in step II) from the extruder through at least one die aperture into an area at lower pressure, with expansion of the foamable polymer melt to obtain an expanded foam, and IV) calibrating the expanded foam from step III) by conducting the expanded foam through a shaping tool to obtain the extruded foam.

Abstract: The present invention relates to a molding made from foam, wherein at least one fiber (F) is partly within the molding, i.e. is surrounded by the foam. The two ends of the respective fibers (F) that are not surrounded by the foam thus each project from one side of the corresponding molding. The foam comprises at least two mutually bonded foam segments.

Abstract: The present invention relates to a composite article comprising at least two layers (A) of component a) and at least one layer (B1) of component b). The respective layers (A) and (B1) are alternately linked together. The component a) has a compressive modulus of at least 10 MPa and can, therefore, be considered as a comparably rigid component, which can be also assigned as rigid core element, in contrast thereto the component b) has a compression stress value at a compression of 40% of not more than 20 kPa. By consequence, component b) can be considered as a comparably flexible (elastic) component. Therefore, the composite articles according to the present invention can be considered as semi-flexible materials due to the combination of alternating rigid and flexible segments (layers) within those composite articles.
