Lightweight support structure, method of producing a lightweight support structure, composite sandwich panel and method of producing a composite sandwich panel

摘要

A lightweight support structure includes a composite sandwich panel having a first face sheet and a lightweight core attached to the face sheet and an essentially rotationally symmetric cut-out extending through the first face sheet and into the lightweight core. The cut-out has an essentially rotationally symmetric inner cut-out and outer cut-out arranged essentially concentric with respect to each other, providing for a support there between. The support has a core support cut from the lightweight core and a support face sheet disc on top, cut from of the first face sheet. A rotationally symmetric insert is fitted into the cut-out for load application and/or anchorage of various components into and onto the sandwich panel.
