A graphitic nanofiber (GNF) surface was successfully modified using the dry-ozone treatment for use as the reinforcement for carbon fiber-reinforced composites (CFRPs). To evaluate the efficacy of the proposed method, CFRPs are fabricated at different weight contents along with two other types of composites (pristine GNFs and dry-ozonized GNFs). We denoted the specimens of GNF/CF/epoxy composites and OGNF/CF/epoxy composites as GCE and OGCE composites, respectively. The mechanical properties including ILSS and KIC were studied for composites to evaluate their efficiency. The measured highest ILSS and KIC value reached 34.2 MPa and 55.4 MPa.m1/2 in the 0.8 wt% OGCE composites, equating to enhancements of 22.6 and 14.2% compared to the 0.8 wt% GCE composites.
