“…At an irradiation dose of 15 Mrad, the reverse process (destruction) is observed, in which the destruction of intermolecular bonds and, consequently, the weakening of the composite, which was previously noted in [1], occurs.…”

“…As the absorbed dose from radiation exposure increases, the degradation process begins to dominate and the material gradually breaks down. As the experiments of the authors [1,26] have shown, noticeable degradation of investigated basalt-composite is evident at irradiation doses higher than 15-20 Mrad. The second point of view (conditionally, it can be called "energetic") is that due to the influence of a concentrated stream of gamma quanta, additional energy is "pumped" into the material, allowing the process of structuring the material to continue, which also leads to a change in mechanical properties.…”

“…The widespread use of composites based on natural minerals is often limited by their insufficient strength. In the previous works of the authors [1,2], the results of mechanical testing of samples from a basalt composite modified by gamma irradiation are presented. It is shown that irradiation can affect the elastic and strength characteristics both in the direction of improvement and in the direction of deterioration.…”

Scanning electron microscopy (SEM) was used to examine the polished surface of samples made of basalt-based composite material before and after gamma irradiation. Morphology and local elemental composition changes in binder, filler and boundary of composite components depending on radiation dose were revealed. The samples were irradiated within a dose range of 5 to 15 Mrad. It has been shown that at radiation doses up to 10 Mrad, new intermolecular bonds are formed and the material is strengthened. With large doses of radiation, the destruction of bonds and the formation of a gas phase is observed. This results in softening of the composite. A sufficiently large amount of nitrogen has been detected in the highly irradiated binder. A possible mechanism has been proposed to explain this phenomenon.

The work is concerned with the study of a relatively new prospective composite material based on basalt fibers. In this work, an attempt has been made to investigate in more depth the structural changes that occur during irradiation of basalt composite samples by gamma ray streams and which affect the mechanical properties. The changes that have occurred during radiation modification have been evaluated by mechanical tests and infra-red spectrum investigations. The impact of the material structure on the elastic properties of the irradiated basalt composite is reasonably assumed. It is discovered that the modification of the material by gamma irradiation leads to an increase in the elastic properties of the basalt composite. At the same time the value of fracture strain decreases. Analysis of the IR spectrum in the high-frequency region showed that the radiation exposure results in continuing polymerization reactions and intermolecular cross-linking. However, when the radiation dose reaches 15 Mrad, there is a reduction in the number of bonds in the low-frequency region of the spectrum, which, according to the authors, corresponds to a breakdown of the aluminum-silicon-oxygen and organo-silicate frameworks
