Abstract
A method and an apparatus facilitate the processing of a core structure for a composite sandwich structure. The core has an open three-dimensional structure and is not self-supporting due to an insufficient strength or stiffness. The method involves temporarily providing a support arrangement on the core structure to mechanically support and stabilize it, then subjecting the supported core structure to the desired processing, and then separating and removing the core structure and the support arrangement from one another. The processing can involve immersion into a processing liquid such as a curable resin, or mechanical machining operations. The support arrangement preferably includes a core impression that is surfacially form-fitting on a structured surface of the core structure. The apparatus includes a support arrangement including a core impression to be disposed on a surface of the core structure. The core impression may be formed of a polymer, a metal, or a casting material.
