The effect of radiation on the properties of glass fiber reinforced plastic of VPS-7 type on the basis of EDT-10 epoxy binder was investigated. Radiation treatment with the maximum dose of 30 MGy was performed for glass fiber reinforced plastic samples in the initial state and after 0.5, 1, 2, and 5 years of exposure in the zones of cold, moderate and warm damp climate. Evaluation of climatic and radiation resistance was conducted by the change in bending strength, interlayer shear strength, Young modulus. Methods of dynamic mechanical analysis and linear dilatometry were employed to investigate the state of epoxy binder during ageing. It has been established that radiation treatment of both initial and climatically aged VPS-7 samples, causes the destruction of the boundary (epoxy binder-glass fiber). The discovered extreme increase of mechanical characteristics of glass fiber reinforced plastic is explained by the competing effects of these two processes. In this case, there is a lack of indications to the occurrence of additional joinings of epoxy binder molecules during irradiation. It has been proved that ageing conducted according to the reverse scheme (radiation treatment with subsequent exposure in the climate) is more rigid and intensifies the effects of the change in the properties of the glass fiber reinforced plastic. |
