Abstract
The results of experimental studies of kinetics of spreading processes of epoxy binders on the surface of a carbon (cloth) tape depending on a reinforcement pattern are presented. A copper coating of 100 nm thickness was deposited on reinforced materials by magnetron sputtering. It has been found out that a metal coating on the surface of a carbon tape and cloth leads to a considerable increase in the rate of spreading processes only for the laying-out pattern 0°, when binder movement in capillaries is provided. The deposition of a copper coating on the surface of the carbon tape and cloth has considerably the bigger influence on kinetics of the spreading processes, increasing it by 35%.
