Abstract
The work is devoted to the study of the effect of various fillers and electron irradiation on the physico-mechanical properties of a number of composite films; fracture models are proposed. A composite material based on polyimide (PI) with various concentrations of the second component: polyethyleneterephthalate, polycarbonate, montmorillonite, hightemperature superconductor, and a polyimide film metallized on both sides was investigated. Samples obtained by the method of mechanical mixing based on polyimide varnish and solutions of the second component. The irradiation was carried out on an electron linear accelerator of the type ELU-6 in air at 25 °C with an energy of 4 MeV. It has been established that the introduction of PET, PC, MM and HTSC fillers makes it possible to obtain materials with desired properties. The concentration of the additive, the features of its internal structure, as well as the technology of synthesis determine the features of the physic mechanical properties of the resulting composite materials.
Electron irradiation causes an improvement in the mechanical properties of some composites, while in others, their deterioration. Various models have been proposed for uniaxial loading of materials and an exponential model gives the best agreement with experiment.
