FIELD: aircraft industry.
SUBSTANCE: invention relates to multilayer structures with aggregates in the form of repeating pyramidal discrete structures and can be used in the production of aggregates for multilayer panels made of various sheet materials that work on the resistance to deformation and stability of the bearing layers when subjected to twisting, bending and compressive forces in many industries. A discrete filler of a multilayer panel is a volumetric structure in the form of repeating pyramidal three-, four- or hexagonal cells isolated from each other or conjugated with each other, having contact pads for connecting to the load-bearing layers or to other layers of the filler. The axes of the discrete cells are oriented at predetermined angles to the base to ensure the required rigidity of the structure and adhere to the skin layers.
EFFECT: creation of reliable and durable discrete filler due to the continuity of the structure, providing high rigidity, as well as creation of reliable connection with the skins.
