Surface energetics and adhesion to epoxy resin were investigated in the laboratory for Kevlar 29 fiber modified by a surface‐controlled nitration reaction and by a nitration/reduction sequence. Results show that at the level of modification studied, the presence of functional groups on the fiber surface does not alter surface energy. On the other hand, interfacial adhesion is significantly increased for the modified as compared with untreated fiber.
