Abstract:
1. A method for the production of a sandwich component comprising a honeycomb core ( 1 ) with a plurality of webs ( 1 ′) and at least two cover layers ( 2 , 3 ) the honeycomb core ( 1 ) consisting of paper, cardboard or other cellulose-based material wherein the cover layers ( 2 , 3 ) are formed from a fiber-reinforced semi-finished material with a thermoplastic matrix, wherein the webs ( 1 ′) of the honeycomb core ( 1 ) are at least partially accommodated in the thermoplastic matrix of the cover layer ( 2 , 3 ) at connecting points (A) to the cover layer ( 2 , 3 ), thus providing a composite of the sandwich component, and wherein the sandwich component has an edge seal created by joining the cover layers ( 2 , 3 ) by local melting of the thermoplastic matrix of the cover layers ( 2 , 3 ), the sandwich component having a flat shape or a shape curved about a radius (R), the method comprising the steps of: providing the honeycomb core ( placing the semi-finished materials above and/or below the honeycomb core, positioning the assembly in a pressing tool with an upper die ( applying pressure and bonding the assembly consisting of the semi-finished materials and the honeycomb core (
