Description of the technology

The nanostructured composite consists of an epoxy resin matrix and a dielectric nanoparticle filler. Before adding nanoparticles to the matrix, the electrical charge of the nanoparticle surface is modified by irradiating nanoparticles with ionizing radiation whose photon energy is higher than 5 eV. The irradiation of nanoparticles is carried out at room temperature (20–25 °C). 

The dependence of the modulus of elasticity and the tensile strength of the epoxy resin composite on the duration of irradiation of SiO2 nanoparticles with ultraviolet radiation is shown the Fig. 1.

Applications The proposed method of nanostructured composites is applicable to aerospace industry, automobile manufacturing, shipbuilding, building construction and other fields of production and construction.
Advantages

After the irradiation of the nanoparticles, the adhesion between the epoxy resin matrix and nanoparticles improves, resulting in an increase in mechanical properties of the nanostructured composite.
