Effect of Carbon Black on Epoxide Resin ED-20 Properties

Abstract

This article describes the effect of carbon black P505 on the bending strength of epoxy resin ED-20. Studies of the effect of the filler concentration of carbon black P505 on the bending characteristics of the epoxy resin composite ED-20 were carried out at temperatures of +23 and -60 °C. Three times decrease in flexural strength and four times in deformability has been observed. When test temperature drops to -60°C, indicators of strength and deformation at failure remain unchanged.
