A graphite fiber (GF) surface was successfully modified using the ozone treatment for use as the reinforcement for carbon fiber-reinforced epoxy composites (CFRPs). To evaluate the efficacy of the proposed method, CFRPs are fabricated at different weight contents along with two other types of composites. We denoted the specimens of GF/carbon fiber/epoxy composites and ozonized GF (OGF)/carbon fiber/epoxy composites as GCE and OGCE composites, respectively. The fracture and interfacial 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 OGCE composites, equating to enhancements of 22.6 and 14.2% compared to the GCE composites.
