[en] Full text: Feature of change structures and dielectric properties on basis epoxide-dianov of pitches ED-20 piezo ceramic fillers PKR-11 and PZT-19 at influence of γ-radiation by the dose 1-3·10⁵ Gy are investigated by method radio-thermoluminescence (RTL). As objects investigation compositions on a basis epoxide pitches ED-20 hardened by various hardeners: PEPA (polyethylene-polyamine) IMTHPA (iso-methyl-terephthaladehyde anhydride) and MEA (methylene anhydride) have been used. To the epoxide pitch softener - Laprols 500, 2500 and 3003 in ratio ED-20: Laprol = 10:1 were also entered. At the next stage an epoxide binding were mixed with filler PKR-11 and PZT-19 taken in volumetric ratios ED-20:filler= 70:30 and 50:50. An epoxide composition were preliminary hardened in steps at temperature 363-448 K within 3 hours. Then radiation modification were held. Spectra of a luminescence of investigated compositions at a dose of an irradiation 10⁴Gy were determined for the first time by RTL method in a wide temperature interval. Maxima relaxation transitions (β-process) on a curves luminescence are observed in a temperature interval of transition from glass form condition in elastic from a dose of irradiation T_β (D) has the S-figurative form. Change of T_β value is apparently explained by fact that under action of γ-radiation in epoxide pitch (with filler and without it) the new spatial circuit is formed. As it is known, increase of density of new circuits influence on α and β processes. After a dose of absorption 0.8-1·10⁵ Gy, process of the saturation, pointing to the end of convection epoxide and hydroxide groups is observed. Observed in spectrum RTL relaxation peak is moved to the high temperature sides on 3-16 K in modified by γ-radiation by the dose 10⁵ Gy compositions, containing softener and filler. Thus, in epoxide compositions with softener intensity of a luminescence grows approximately from 2 up to 6 times depending, on type a hardener and 3 times at a introduction filler. It is revealed, what at a dose 2-2.5·10⁵ Gy in filled epoxide compositions on action of γ-radiation and the volumetric contents filler on character of change ε(T), tgδ(τ) and E_p(D) there in an additivity. So, in composites containing 30 vol. % PKR-11 and PZT-19 with increase of a dose a maximum of the factor of dielectric losses tgδ(τ) max and dielectric permeability ε(T) is displaced aside the raised temperatures. The received results prove, that varying a nature ceramic fillers, hardeners and softeners and simultaneous influence by γ-radiation effectively it is possible to adjust structures to change a complex of electrophysical properties epoxide compositions
