Abstract The paper presents the results of study effect electron irradiation on PTFE composite material containing tungsten (VI) oxide. physical and mechanical characteristics with 60 wt% filling have been studied, density is 3.4 ± 0.02 g cm −3 , Vickers hardness 5.4 0.32 HV, flexural strength 19 0.95 MPa. was irradiated electrons at Microtron-ST accelerator an beam 21 MeV energy 5 μA current. XRD WO 3 after show broadening peaks, which indicates deformation crystal lattice a change in degree crystallinity component. investigation FTIR spectra before are presented. Electron pure led to changes intensity some bands spectrum. In particular, were more prominent range from 525 800 −1 . case material, spectrum less pronounced. TGA showed no significant changes. influence different doses thermophysical properties studied. It shown that under dose 2 MGy sample decreases 2.8 times. For bending 46% initial not irradiated.
