Summary: | Surface treated fibers and methods of treating individual fiber surfaces. One exemplary method includes subjecting a precursor gas to a plasma-generating discharge within an atmospheric plasma generator to generate a reactive species flow including reactive oxygen species, and exposing a reinforcing fiber to the reactive species flow for a treatment time sufficient to functionalize the reinforcing fiber with oxygen such that at least one of a composite matrix interfacial adhesion of the reinforcing fiber or a composite matrix interfacial strength of the reinforcing fiber, increases. The precursor gas preferably includes a carrier gas and an oxidative gas, the oxidative gas being contained in an amount of up to 25% by volume of the precursor gas. |
