FIELD: technological processes.
SUBSTANCE: invention relates to production of articles from carbon composite reinforced polymer composites, specifically to electrophysical hardening of finally formed articles of different complexity, and can be used in the manufacture of parts of transport vehicles, in particular – aircraft, to strength and durability of which high demands are made. Method of increasing efficiency of microwave treatment, using complex effect on processed object of microwave field energy and energy of ultrasonic vibrations, consists in the fact that ultrasonic vibrations are excited in the processed object in the form of bending waves, which antinodes coincide with the areas of minimum microwave field intensity in the radiating antenna directional pattern, and node points are aligned with areas of maximum intensity of microwave field, wherein ultrasound sources are located on both sides of horn of radiating antenna behind its plane in rear zone at a distance from each other, multiple to a whole number of wavelengths in said type of polymer composite material, and ultrasonic waveguides are brought into power contact with surface of processed object. If it is necessary to process objects of large size and complex shape, ultrasonic waveguides and emitting horn antenna are synchronously moved in two mutually perpendicular planes for uniform ultrasonic and microwave effect on the entire processed surface.
EFFECT: technical result consists in improvement of strength characteristics by modulus of elasticity at interlayer shift at (8–13) % and reduction of dispersion (high stability of processing batch of articles) of said parameter and limiting stresses in finally formed structures from hardened multilayer composite materials reinforced with carbon fiber, in 5–8 times due to application of ultrasound and microwave treated of final product.
