FIELD: technological processes.
SUBSTANCE: invention concerns composite structure, method of its obtainment, and application. Composite structure is a sandwich structure consisting of two outer structural layers L1 and L3 and one inner lightening layer L2, made of solid or semisolid polyamide foam. Structural layer is a plate or sheet made of thermoplastic or heatset polymer matrix reinforced by reinforcement fiber, or a metal or metal alloy plate or sheet. Method of obtaining composite structure involves conjunction of the following elements: structural layer L1, lightening layer L2 of polyamide foam or the said foam precursor, structural layer L3. Composite structure can be applied in car or airplane part manufacturing, or production of sports gear, such as ski, or in construction panel manufacturing.
EFFECT: obtaining hard and light reusable composite structure.
