Abstract
A composition is disclosed for treating carbon fibers to provide an epoxy finish thereon, comprising an epoxy resin and an effective amount of a non-ionic emulsifier in the form of a block polymer consisting of a poly(oxypropylene) chain having poly(oxyethylene) groups at both ends of said chain, said polymer terminating in a primary hydroxyl group, said polymer having a molecular weight ranging from about 1100 to about 14,000. The process for treating the carbon fibers comprises applying the aqueous resin emulsion to the fibers and thereafter drying the fibers.
