A method for producing a sandwich component, in particular an inner trim component for a motor vehicle, is disclosed. The method begins with a core layer made from a foamed plastic and a cover layer which includes reinforcing fibers and plastic fibers. The plastic of the core layer has a first melting temperature which is higher than the second melting temperature of the plastic fibers of the cover layer. By the core layer being arranged on the cover layer, a multilayer composite is created. This multilayer composite can be further processed into a semi-finished product. The multilayer composite or the semi-finished product is then heated in a heating device to a temperature which is lower than the first melting temperature but therefore higher than the second melting temperature. Then the heated multilayer composite or the semi-finished product is formed in a forming tool in order to produce the sandwich component.

Method for producing a sandwich component and sandwich component

A sandwich component () having a honeycomb core layer () and at least one fiber-reinforced thermoplastic outer layer () and the corresponding production method. The outer layer () is connected to the honeycomb core layer () by a thermoplastic material. At least one side of the sandwich component (has a decorative layer ('), which is arranged on the outer layer (). The sandwich component () furthermore has at least one foam layer (), which is arranged between the outer layer () and the decorative layer (&#x2032;), and which is connected to the outer layer () and the decorative layer (&#x2032;).
