The purpose of the study is to study the influence of nanofiller (aluminum nitride and nanoalmases) on the structure and physical and chemical properties of epoxy polymer composites and surface functionality of these nanoparticles with amino acetic acid. In the course of the study, the optimal concentrations of 5% and 7.5% of the amino acetic acid required to ensure uniform distribution of nanoalmases (NA) and aluminum nitride (AlN) particles in the polymer matrix. It was found that the listed concentrations of the functionalizing agent lead to a significant increase in the mechanical properties of composites: as a result of the introduction of functionalized nanofillers with nano-fillers, an increase in bending strength, modulus of elasticity, tensile strength, impact resistance and heat resistance of epoxy composites was observed. The maximum increase was 6-50%. 0.1 drunk. HA and 0.05 drunk.H. With the introduction of AlN, the greatest mechanical and thermal characteristics were achieved, that is, this led to an increase in heat resistance from 100-110°C to 132-168°C. Pure and functional nanoparticles have also increased fire resistance by reducing mass loss and increasing the oxygen index. In general, these nanocomposite materials have exceptional mechanical, thermal and refractory properties, which is very important for modern applications with stable strength and fire resistance.
