Epoxy resin is extensively applied in the electronics and electrical fields because of its outstanding comprehensive performance. However, the low thermal conductivity (TC) limits its application in thermal interface materials. In the present work, epoxy-based hybrid composites with high TC were prepared by using expanded graphite (EG) and copper (Cu) nanoparticles as thermally conductive hybrid fillers via hot blending and compression-curing processes. Additionally, the influence of the Cu content on the thermal properties, mechanical properties, and morphology of each epoxy/EG/Cu composite was investigated. According to the results, the epoxy/EG/Cu composite showed a maximum TC of 9.74 W/(m·K) at a fixed EG content of 60 wt % owing to the addition of 10 wt % Cu. After the addition of 10 wt % Cu, the flexural strength, flexural modulus, and impact strengths of epoxy/EG/Cu composites were improved from 27.9 MPa, 9.72 GPa, and 0.81 kJ/m2 to 37.5 MPa, 10.88 GPa, and 0.91 kJ/m2, respectively. Hence, this study offers a feasible strategy for the design of epoxy hybrid composites with excellent TC that can be applied to thermal interface materials.

To enhance the performance of carbon fiber reinforced polymer (CFRP), it is crucial to establish robust interactions between epoxy and carbon fiber fabric (CFF). Herein, CFF was treated by an optimized H2O2/H2O/O3 oxidation method. The chemical and physical properties of the treated CFFs were meticulously characterized. For comparison, CFF, O3 treated CFF, and H2O/O3 treated CFFs were also examined. It was found that H2O2/H2O/O3 oxidized CFF more effectively than either O3 or H2O/O3. Reactive O groups were extensively grafted onto the surface of the H2O2/H2O/O3 oxidized CFF, leading to an increase in surface energy. Additionally, numerous defects were introduced on the surface of the H2O2/H2O/O3 oxidized CFF, significantly enhancing its surface roughness. Consequently, the interlaminar shear strength of H2O2/H2O/O3 oxidized CFF reinforced epoxy composite reached 63.31 ± 2.50 MPa, which is 43.3% higher than that of CFF reinforced epoxy composite. The fracture surface morphology and differential scanning calorimetry studies confirmed the presence of strong interfacial chemical interactions, while the increased surface roughness ensured robust interfacial physical interactions. Based on these findings, the mechanisms of the H2O2/H2O/O3 oxidized CFF reinforcing epoxy were proposed. The present work aims to give out some ideas for the fabrication of green and advanced CFRP.Highlights CFF was effectively oxidized by an optimized H2O2/H2O/O3 method eco‐friendly. Improved the interlaminar shear strength of the epoxy composite by 43.3%. Both the strong interfacial chemical and physical interactions were confirmed. The reinforcing mechanism is attributed to the robust interactions.
