Kevlar-49 fiber was surface-modified through cold air plasma treatment and plasma grafting of acrylic acid (AA).Fiber surface properties were studied with ESCA,while interface properties with a single fiber pull-out (SFPO) test.The stated surface modifications evidently improved the interfacial adhesion and increased the interfacial fracture energy of the aramid/epoxy composite system.
