Abstract

Process of selection of ratio of components of prepreg is described. The data on electrochemical corrosion in the contact zone of «metal–carbon» fiber and describes a method of protection against contact corrosion by isolating the carbon-plastic metal layer prepreg GRP. The initial components of prepreg GRP VPS-53/120, designed to prevent contact corrosion between metal and carbon fiber, were selected. Two methods for calculating the surface density of the binder and prepreg are described. The ranges of permissible dispersion of the surface densities of the binder and prepreg film are calculated taking into account the dispersion of the surface density of GRP and the selected range of the binder content in the prepreg. The actual values of the prepreg characteristics of the VPS-53/120 brand are determined and their statistical analysis is carried out, the high convergence of the actual values with the calculated ones is shown. Physical-mechanical and operational characteristics of GRP of the VPS-53/120 brand are defined.
