Method for producing a sandwich component and sandwich component

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.
