In the article a technique is provided that allows to optimize the process of choosing a rational composition of particulate filled polymer composite materials (PFPCM) based on the estimation of specific adhesive energy. Specific adhesive energy is calculated assuming the oriented surface layer formation and using a structure of representative volume. Strength tests for a variety of PFPCMs were conducted. Comparison of analytical results with the results of strength tests showed that that the higher the value of the specific adhesion energy that the system possesses, the higher its strength characteristics. Thus, this technique provides an assessment of strength characteristics of PFPCM based on data on its granulometric composition, filling ratio and type of binder.

The Matrix

Based on studies of the microstructure of the matrix of cured polymer composite materials and the area of its contact interaction with reinforcing fibers, the hypothesis of its structuring in the microwave electromagnetic field with an increase in the contact interaction surfaces due to an increase in the number of agglomerates with small transverse dimensions and a decrease in porosity in the macro- and mesopore regions is substantiated. These effects can be used as a basis for increasing the strength characteristics and uniformity of their values after exposure to a microwave electromagnetic field. The results of this work can be used in the development of technologies for finishing hardening of products made of carbon and fiberglass for various transport and energy systems.

Surface Layer Formation

Leachability is one of the most important properties of solidified nuclear waste forms because it provides information on the performance and the subsequent safety and reliability that the waste products will possess. One of the most important experimental findings in the leachability field has been the discovery and subsequent detailed characterization of protective surface layers that form on waste glass during leaching. These layers can have a beneficial effect on product performance while in storage by improving productdurability with time. As a result of surface layer formation and the effects on subsequent product leaching characteristics, new qualitative and quantitative leaching models have recently been proposed.
