Abstract

Four types of metal coatings made of stainless steel, silver, titanium and copper were deposited on the surface of unidirectional carbon tape by the magnetron sputtering technology. The experimental evaluation results of strength of elemental carbon fibers with the metal coatings and strength of carbon-filled plastics based on them during the interlaminar displacement are presented. When producing the carbon-filled plastics an epoxy binder and the vacuum infusion technology were used. It has been found out that all the used metal coatings lead to an increase in strength of the carbon-filled plastics during the interlaminar displacement. The carbon tape with the stainless steel coating has the highest strength increase (by 50%). However, during long-term storage, the coating effectiveness of the metalized carbon tapes decreases.
