This study is aimed to estimate thermal and mechanical properties of carbon fiber-reinforced plastics processed from prepregs in the presence of nanoparticles of various structure (carbon or silicate) and morphology (flat or tubular). Prepregs of fiber-reinforced plastic based on Porsher-43200 carbon twill weave fabric and thermoreactive polymer matrices were fabricated using electrostatic spraying, subsequently the prepregs were rolled in temperature-controlled calenders. Solid epoxy olygomer Epicote 1004 with dicyandiamine Casamid 780 was used as a thermoreactive matrix. Montmorillonite, halloysite, graphitized carbon nanofibers and nanocones were used as nanomodifying agents for epoxy oligomer. The results of the research showed the efficiency of modification of epoxy binders by nanoparticles to improve the functional properties of reinforced carbon plastics and their fabrication technology.
