The effect of two-component bidisperse filler on the physico-mechanical and thermophysical properties of epoxy composites has been studied. A coating with an aluminum oxide content of 60 parts by weight and a crystalline boron content of 40 parts by weight per 100 parts by weight of ED-20 epoxy oligomer and 10 parts by weight of a hardener (polyethylenepolyamine) with improved operating characteristics has been developed. The reliability of the obtained results is verified by modern methods of investigation, i.e., by the thermogravimetric and differential thermal analysis of materials under investigation.
