| description | Sheet type semi-finished product comprises at least a core made of mat shaped layer of fibrous materials, preferably heterogeneous fiber blends, or an open- or mixed-cell foam material or mixtures of fibrous materials and foam material. The mat shaped layer is impregnated with an impregnate comprising a thermally-curable binder and a thermally expandable filler. The filler forms gas-filled cavities or regions of reduced density in the thermally expanded state. Independent claims are also included for: (1) a thermoformed acoustically active molded part; (2) producing the sheet type semi-finished product for producing thermoformed, acoustically active molded part, comprising (a) a providing the mat shaped layer, (b) providing the impregnate, (c) impregnating the mat shaped layer with the impregnate, and (d) drying the impregnated mat shaped layer; and (3) producing the thermoformed acoustically active molded part, comprising (i) introducing a section of the sheet type semi-finished product in the open cavity of a heated molding tool, (ii) closing the cavity of the molding tool and thermoforming acoustically active molded part of the sheet type semi-finished product under thermal curing of the binder and thermal expansion of the filler.
Gegenstand der Erfindung ist ein flächenförmiges Halbzeug zur Herstellung von thermogeformten, akustisch wirksamen Formteilen sowie ein Verfahren zzur Herstellung eines derartigen Halbzeugs. Das Halbzeug umfasst zumindest einen Kern aus einer mattenförmigen Lage aus faserigen Materialien, vorzugsweise aus heterogenen Fasermischungen, oder aus einem offen- oder gemischtzelligen Schaumstoff oder aus Mischungen von faserigen Materialien und Schaumstoffen. Die die mattenförmige Lage mit einem Imprägnat imprägniert ist, welches ein thermisch aushärtbares Bindemittel umfasst. Weiterhin betrifft die Erfindung thermogeformte, akustisch wirksame Formteile sowie Verfahren zu deren Herstellung. |
