Abstract: Primer layers for adhesion of pressure sensitive adhesive materials to substrates comprise a cured primer which is the reaction product of an epoxy resin and a polyamine. The epoxy resin may be an aromatic epoxy resin. The polyamine may be a polymer such as polyethylenimine (PEI) or polyvinylamine (PVA). Two-layer constructions comprise the primer layer according to the present disclosure and a substrate layer, which may be directly bound to the primer layer. The substrate layer may comprise one or more polyester polymers, may comprise one or more polymers comprising aromatic groups, and/or may comprise polyethylene terephthalate (PET). Tapes comprise the two-layer construction according to the present disclosure and a pressure sensitive adhesive layer, which may be directly bound to the primer layer. The tape may comprise a second pressure sensitive adhesive layer borne on the opposite face of the tape and optionally a foam layer.

Abstract: 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.
