HIGH-STRENGTH REINFORCING ELEMENT FOR HYDROACOUSTIC COATINGS Russian patent published in 2021 - IPC G10K11/168 

FIELD: building.

SUBSTANCE: area of application: the invention is aimed at creating a new high-strength reinforcing element for hydroacoustic coatings using an advanced 3D printing technology and generative (bionic) design of the structure. Substance: the unique feature of the invention is the proposed shape of a reinforcing element with a large specific area of cutouts on the surface, allows for an increase in the acoustic efficiency in the HACs applied to reduce the noise levels of an object located in water under the impact of hydrostatic pressure. The developed high-strength reinforcing element for hydroacoustic coatings, due to the rational configuration of the structure based on bionic design, provides an improved distribution of stresses, i.e., reduction therein by more than 1.5 times on the most stressed sections of the surface at equal load conditions compared with a serial reinforcing element. Also, due to modernisation of the shape of the bases and the rod, the weight of the reinforcing element is reduced by 2 or more times while simultaneously increasing the specific surface providing elastic deformation of the surrounding material, which is one of the significant parameters in manufacturing the HAC.

EFFECT: creation of a high-strength reinforcing element with a large specific area of cutouts on the surface using a 3D printing technology and bionic design in order to increase the parameters of acoustic efficiency in a wide range of hydrostatic pressures.
