Abstract New types of composites based on element‐containing carbon fibers (ECFs) and an epoxy binder have been developed. The results show that the presence of functional groups within the ECF structure affects significantly the reaction mechanism of the epoxy matrix. Connections between processes occuring in the interphase zone (the boundary layer) and the properties of hardened composites have been revealed. The factors controlling the binder hardening reactions occuring on surfaces of interphases when creating composites with improved physical and mechanical properties as well as with predermined service properties (polishing, anion‐exchange, anti‐corrosion, flame‐resistance, controlled range of electrical resistance etc) are defined. A potential for using ECFs in a role unusual for them, namely as hardeners for epoxide binders, has been established. Applications of reactive ECFs which may function both as a filler and as a hardener provides longer service life of the composites and minimizes the amount of volatile products released in the process of hardening.
