Conclusions 1. The damping properties of composite bars are increased by enlarging the layer of test composite. 2. A sublayer of adhesive 0.03–0.05 mm thick has practically no effect on energy dissipation in the bar. 3. The logarithmic vibration decrement of a compound bar increases with increasing angle of the reinforcing composite and reaches a maximum at a fiber orientation angle of ± 45°. 4. With increasing relative strain in the test range the logarithmic vibration decrement for a compound bar increases, and it increases more by enlargingthe disorientation angle for fibers in the composite to ± 45 °. Thus, by constructing polymeric composites it is possible to alter the damping properties of metal structures reinforced with composites over a wide range, and to make it possible to obtain the required material properties for the structure.
