Producing a three dimensional contoured sandwich structure including first thermoplastic covering layer, second thermoplastic covering layer and core material, comprises e.g. machining or carrying out separate processing of core material

摘要

Producing a three dimensional contoured sandwich structure consisting of a first thermoplastic covering layer, a second thermoplastic covering layer and a core material with a honeycomb structure, arranged between the covering layers, comprises (a) machining and/or carrying out separate processing of the core material until the desired three-dimensional contour is obtained, (b) sequentially or parallely cutting the covering layers of the three-dimensional contour, and (c) applying thermoplastic covering layers onto the processed core material and cohesively connecting by hot pressing. Producing a three dimensional contoured sandwich structure consisting of a first thermoplastic covering layer, a second thermoplastic covering layer and a core material with a honeycomb structure, arranged between the covering layers, comprises (a) machining and/or carrying out separate processing of the core material (contouring process) until the desired three-dimensional contour is obtained, (b) sequentially or parallely cutting the covering layers of the three-dimensional contour obtained in the step (a), and (c) applying thermoplastic covering layers onto the processed core material and cohesively connecting by hot pressing.
