In this article, aramid fibers III were surface modified using an ammonia-plasma treatment to improve the adhesive performance and surface wettability. The surface properties of fibers before and after plasma treatment were investigated by X-ray photoelectron spectroscopy, scanning electron microscopy, atomic force microscopy, and water contact angle measurements. The interfacial shear strength of each aramid fibers III-reinforced epoxy composites was studied by micro-debonding test. The ammonia-plasma treatment caused the significant chemical changes of aramid fibers III, introducing nitrogen-containing polar functional groups, such as CN and CONH, and improving their surface roughness, which contributed to the improvement of adhesive performance and surface wettability.
