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

摘要

A light support structure (1) comprising: - a composite sandwich panel (5) comprising: - a first face sheet (10); - a light core (15) fixed to the first face sheet (10); - an optional second face sheet (20) fixed to the light core (15) and opposite the first face sheet (10); and - an essentially rotating symmetry cutout (30) extending through the first face sheet (10) and into said light core (15), and - a rotating symmetry insert (50) fitted in said cut-out (30) for the application of loading and / or anchoring of various components, respectively, in the composite sandwich panel (5), characterized in that: - the cut-out (30) comprises an inner cut of essentially rotating symmetry (31) and an outer trimming of essentially rotating symmetry (32) arranged essentially concentric with each other, providing a support (40) between them; - said support (40) comprises a core support (41) cut from said light core (15) and a support face blade disc (42) at the top, cut from said first face sheet (10); and - the core support (41) is preferably compressed to allow said insert (50) to be flat inside the composite sandwich panel (5).
