Conclusions 1. The anisotropy of the viscoelastic properties of three-layer organometallic plastics, caused by the presence of an anisotropic unidirectional organoplastic in the composite, which is significantly attenuated by the isotropic aluminum layers, was studied by the method of bending resonance vibrations. 2. The surface layers make the basic contribution to the formation of the viscoelastic properties of three-layer organometallic plastics. The adhesive interaction between the components of the composite and the internal thermal stresses on the metal-polymer interface result in stiffening of the structure of the polymer matrix, which affects the dynamic viscoelastic properties (shift of the temperature of α1 relaxation by 50–60 °C to the high-temperature region). 3. An increase was found in the anisotropy coefficient of the polymer matrix in going from the glassy to the highly elastic state, caused by weakening of the role of the binder in the formation of the properties of the organometallic plastics. 4. Anisotropy of the mechanical glass transition temperature of the polymer matrix of the organometallic plastic was found, caused by a change in the contribution of the components to the formation of the properties of the composite when the angle between the axis of the sample and the axis of the reinforcement change.
