Abstract (en)
[origin: CA2704143A1] The present invention relates to a method for producing a sandwich structure that is easy to produce and comprises particular physical and/or chemical properties. A method for producing said sandwich structure is proposed to this end, comprising the steps: a) lay-up of a first cover layer (3) in an injection mold, b) lay-up of a second cover layer (3) in the injection mold, c) closing the injection mold, d) injecting a core material into the closed injection mold between the first and the second cover layer (3) by means of injection molding, e) curing of the core material, so that a core layer (2) is formed between the two cover layers (3), and f) opening the injection mold and demolding the sandwich structure (3).
