Abstract

Kratowa warstwa środkowa jest wykonana z połączonych na zakładkę prętów kompozytowych o bokach prostoliniowych przecinających się pod kątem prostym, między którymi znajdują się oddzielne komórki przestrzenne, które mogą być puste lub wypełnione jednorodnym lekkim materiałem konstrukcyjnym o pożądanych własnościach akustycznych. Równoległe płaskie powierzchnie prętów, dolna i górna są połączone trwale z zewnętrznymi warstwami panelu sandwich. Pręty kompozytowe tworzące kratową warstwę środkową panelu mają w przekroju poprzecznym kształt wieloboku wklęsłego z rdzeniem (1) z lekkiego materiału konstrukcyjnego oraz laminatową warstwą zewnętrzną złożoną z dwóch części, lewej (2) i prawej (3), połączonych z rdzeniem (1), które stykają się ze sobą wzdłuż dwóch linii prostych na płaskich powierzchniach pręta przylegających do zewnętrznych warstw panelu sandwich.The lattice middle layer is made of overlapped composite rods with rectilinear sides intersecting at a right angle, between which there are separate spatial cells that can be hollow or filled with a homogeneous lightweight construction material with the desired acoustic properties. Parallel flat surfaces of the bars, lower and upper are permanently connected to the outer layers of the sandwich panel. Composite bars forming the lattice middle layer of the panel have a cross-sectional shape of a concave polygon with a core (1) of lightweight construction material and a laminate outer layer consisting of two parts, left (2) and right (3) connected to the core (1), which they touch each other along two straight lines on the flat surfaces of the rod adjacent to the outer layers of the sandwich panel.
