The main problem for silicone rubbers is the selection of a plasticizer that is compatible with the rubber. Due to the nature of silicone rubber (its polarity), it is not possible to use almost all common plasticizers. Therefore, finding a plasticizer that would be compatible with siloxane rubber, while not negatively affecting the heat and fire resistant properties of rubbers based on siloxane rubber, is of scientific interest and practical significance. The influence of three plasticizers with different ratios of organic and inorganic (siloxane rubber destructate) components and their content on the physical-mechanical, thermal and fire resistance of siloxane rubbers has been studied.

his paper presents the result of studies of changes in the structure and mechanical properties of fiberglass based on an epoxyanhydride binder with fillers of carbon nanotubes (CNT) and dispersed silicon carbide powder (SiC). The result of the work is a dynamic mechanical analysis and assessment of the influence of fillers on the glass transition temperatures of fiberglass.
