COMPOSITE LINING ABSORBING ACOUSTIC VIBRATIONS OF A THIN-WALLED METALLIC STRUCTURE

摘要

At the surface (1) thin-walled metal structure (2) is subsequently applied and cured composite liner (3), thereby forming a dismountable unit. Composite lining (3) consists of two connected layers znejméně whose modulus of elasticity is different, the layers are placed so that towards the surface (1) thin-walled metal structure (2) is a modulus of elasticity of the layers reduced. Composite lining dampens vibrations of thin-walled metal structures, particularly rugged area of ​​the air inlet channel motoru.ŕ
