The paper presents the results of studies of the influence of carbon nanotubes (CNTs) on radio engineering (reflection coefficient), electrophysical (surface electrical resistance), thermomechanical and strength properties of fiberglass based on epoxy binder. The compositions and technological parameters of the manufacture of fiberglass samples are proposed. The change in the electrophysical and radio technical characteristics of fiberglass samples with increasing concentrations of CNTs is shown.

“…This problem can be solved by increasing the fraction of the organic part in the siloxane modifier 25 . Incorporation of epoxy‐functional organosilsesquioxanes as co‐curing agents also decreases the exothermic effect of curing and increases the heat resistance of the resulting material 26 …”

In this work, the curing of «ED‐20» epoxy resin with partially siloxy‐substituted aluminum, iron, and zirconium siloxanes that we obtained previously was studied. The initial content of a metallosiloxane in the compositions was 5–50 wt% with respect to the resin. In all the cases, thermal curing was used to obtain a series of samples in the form of solid homogeneous materials. The fact of the epoxy ring opening in the resin was confirmed by IR spectroscopy. The catalytic properties of the metal atom in a metallosiloxane were found to affect the curing process. The samples demonstrate rather a high resistance to thermooxidative destruction, and in most cases, their glass transition temperatures are lower than those obtained upon standard curing of «ED‐20» resin with triethylenetetramine. Partially siloxy‐substituted metalloalkoxysiloxanes can be efficient agents for curing and formation of a hybrid material based on epoxy resins.
