Abstract
The paper discusses polymeric insulating materials: polyethyleneterephthalate, polyimide, phenylone. Their mechanical properties are investigated. Various models of materials destruction are proposed. It was established that the mechanical properties of the films depend on the structure and conditions of their synthesis. The globular structure of polymers determines their fragility. The destruction, as a rule, occurs along the boundaries of globules weakly interconnected. Mechanical influences lead to the ability of the globule to unfold, and the globular structure becomes fibrillar, which leads to severe deformations of polymers. In the case of uniaxial loading of materials, an exponential model was calculated. A good agreement between the calculated and experimental data was obtained.
