CREATING HOLES IN SOUND-ABSORBING STRUCTURES DURING MOLDING
Monolithic samples are made of carbon fiber based on fabrics that are cured by infusion. Perforation is carried out on a CNC milling machine after confirmation and on special equipment until confirmation. Samples are cut from the plate at an angle of 4-5°, as the orientation of the holes in real sound-absorbing structures. Samples tested for tensile strength according to GOST 56785-2015. Samples cut from plates made by molding give 25% higher results than samples obtained by processing on a CNC machine
