Abstract: High-strength polyethylene fiber (Dyneema SK60) was surface modified through cold air plasma treatment. Poly(acrylic acid)(PAA)and poly(acrylic acid-co-ethyl acrylate) (P(AA/EA)) were grafted onto plasma activated Dyneema SK60 fibers. Fiber interfacial properties were studied with a single fiber pull-out test. The stated surface modifications evidently improved the interfacial adhesion and increased the interfacial fracture energy of the Dyneema/epoxy composite system.

Key words: high strength polyethylene fiber, plasma, surface modification, interfacial property
