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.

通过蒸汽辅助臭氧,绿色地在环氧树脂和碳纤维织物之间建立强相互作用

为了提高碳纤维增强聚合物(CFRP)的性能,在环氧树脂和碳纤维织物(CFF)之间建立牢固的相互作用至关重要。在此,CFF经过优化的H处理22/H2输出/输出3氧化法。经过处理的 CFF 的化学和物理特性经过精心表征。作为比较,CFF、O3处理过的 CFF 和 H2输出/输出3还检查了经过处理的 CFF。结果发现,H22/H2输出/输出3氧化 CFF 比 O 更有效3或H2输出/输出3。反应性O基团被广泛接枝到H表面22/H2输出/输出3氧化CFF,导致表面能增加。此外,H 表面引入了许多缺陷。22/H2输出/输出3氧化CFF,显着提高其表面粗糙度。因此,H 的层间剪切强度22/H2输出/输出3氧化后的CFF增强环氧复合材料达到63.31±2.50 MPa,比CFF增强环氧复合材料高43.3%。断裂表面形态和差示扫描量热研究证实了强界面化学相互作用的存在,而表面粗糙度的增加确保了强大的界面物理相互作用。基于这些发现,H 的机制22/H2输出/输出3提出了氧化CFF增强环氧树脂。本工作旨在为绿色、先进碳纤维复合材料的制造提供一些思路。 CFF 被优化的 H 有效氧化22/H2输出/输出3方法环保。 环氧复合材料的层间剪切强度提高了43.3%。 强烈的界面化学和物理相互作用都得到了证实。 强化机制归因于强大的相互作用。
