Aramid fibers were chemically treated to improve their wetting characteristics and to selectively bond suitable coupling agents to their surface. It was found that an organic coupling agent, which had been reactively bonded to the surface of the aramid fibers and contained an unsaturated pendant group, not only significantly improved the wetting performance of the fibers but also increased the adhesion of polyester resin to the fibers by approximately 200%. This increase in adhesion is attributed primarily to chemical rather than physical bonding. It is suggested that the unsaturated end groups of the attached coupling agent cross-link with the polyester resin during the curing process.
