Abstract
There is disclosed a method of treating carbon fibers to provide an epoxy resin finish thereon. An aqueous emulsion of an epoxy resin is applied to the fibers and the fibers are thereafter dried. An effective amount of two different emulsifying components are used in the epoxy resin emulsion. One of the emulsifying components is a long chain aliphatic alcohol containing from eight to 18 carbon atoms. The other emulsifying component is a quaternary ammonium salt having the formula: ##STR1## wherein R is an aliphatic radical containing from 12 to 18 carbon atoms, or a mixture of such radicals, each R' may be the same or different radicals selected from methyl and ethyl, and x is bromine or chlorine.
