The electropolymerization of methyl methacrylate and methyl acrylate was investigated. The reactivity ratios of the monomers in this electrochemically initiated reaction were calculated and found to be equal to 0.33 and 0.89, respectively. The composition of the monomer-electrolyte solution and the parameters of the electrocopolymerization-coating process, which provides formation of thin (submicrometre) even coatings on carbon fibres (CF), were found. Composites from CF coated with the methyl methacrylatemethyl acrylate copolymer showed an improved strain energy release rate (40-200%) and interlaminar shear strength (up to 20%) in comparison with specimens from untreated CF. A pot-life of more than 1 month for the monomer-electrolyte solution was achieved.
