Method for producing an SMC multi-layer component in a production process. The component has a sandwich structure. At least one foam material layer ( 3 ) is embedded between two SMC cover layers ( 2, 2′ ). An insert layer arrangement comprising at least one first and one second SMC semifinished product cover layer ( 2, 2′ ) is positioned in a press mold comprising a punch ( 1 ) and a die ( 1′ ). A first and a second SMC semifinished product cover layers ( 2, 2′ ) are shaped into two SMC cover layers ( 2, 2′ ) by applying pressure to the layer arrangement. Curing of the first and the second SMC semifinished product cover layers ( 2, 2′ ) is initiated. The punch ( 1 ) and the die ( 1′ ) are moved away from each other, until the distance provided therebetween corresponds to a thickness of the SMC multi-layer component to be produced. A foaming process of a material ( 3′ ) that can be foamed, which is provided between the two SMC cover layers ( 2, 2′ ) is initiated, producing the foam material layer ( 3 ). After the foaming has ended, the SMC multi-layer component is removed from the press mold.
Opening claim text (preview).
The invention claimed is: 1. A method for producing an SMC multi-layer component in a production process, wherein the component has a sandwich structure and at least one foam material layer ( 3 ) is embedded between two SMC cover layers ( 2 , 2 ′), comprising the steps of a) positioning an insert layer arrangement comprising at least one first and one second SMC semifinished product cover layer ( 2 , 2 ′) in a press mold comprising a punch ( 1 ) and a die ( 1 ′), b) shaping a…
