METHOD OF MAKING PART AND PART FROM HYBRID COMPOSITE MATERIAL Russian patent published in 2019 - IPC B32B7/04 B32B15/14 B64C1/00 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aircraft engineering, namely, to production of given curvature laminar hybrid composite materials of aircraft parts, including parts subjected to intensive thermal erosion action. Method involves preliminary preparation of metal sheets and composite material, assembly of stack-billet consisting of a given number of alternating layers of metal sheets and composite material, and its preliminary molding to form a flat workpiece, which or then are laid on the shaping tool in a given sequence for subsequent molding part of a given shape on a mode providing polymerization of the binder, removal from the tooling. Preforming is carried out at temperatures below the polymerization temperature of the adhesive binder in the composite material. Content of metal in the material is selected in range from 13.2 % to 88.3 % depending on the purpose and structure of the manufactured part.

EFFECT: invention enables to obtain parts of a given curvature of hybrid laminar composite material, having high resistance to thermal erosion action and impact resistance, and improved manufacturability of parts with variable thickness and parts with minimum possible radius of bending.
