FIELD: technological processes.
SUBSTANCE: method consists in formation of prepreg in mould with elastomer inserts and thermal treatment of foaming material. Formation of aerodynamic body of integral design is done in a single stage, by formation of prepreg and foaming material in mould with their simultaneous laying, thermal treatment and further cooling. Foam plastic filler is created, which is placed between layers of prepreg, creating integral structure with three-layer sections.
EFFECT: reduced number of operations for manufacturing of integral structure.
