The current study investigated the effect of adding a carbon nanotube-alumina (CNT-Al₂O₃) hybrid on the fracture toughness of epoxy nanocomposites. The CNT-Al₂O₃ hybrid was synthesised by growing CNTs on Al₂O₃ particles via the chemical vapour deposition method. The CNTs were strongly attached onto the Al₂O₃ particles, which served to transport and disperse the CNTs homogenously, and to prevent agglomeration in the CNTs. The experimental results demonstrated that the CNT-Al₂O₃ hybrid-filled epoxy nanocomposites showed improvement in terms of the fracture toughness, as indicated by an increase of up to 26% in the critical stress intensity factor, , compared to neat epoxy.
当前的研究调查了添加碳纳米管 - 氧化铝（CNT - Al₂O₃）杂化物对环氧纳米复合材料断裂韧性的影响。通过化学气相沉积法在Al₂O₃颗粒上生长碳纳米管来合成CNT - Al₂O₃杂化物。碳纳米管牢固地附着在Al₂O₃颗粒上，这有助于均匀地传输和分散碳纳米管，并防止碳纳米管发生团聚。实验结果表明，与纯环氧树脂相比，填充CNT - Al₂O₃杂化物的环氧纳米复合材料在断裂韧性方面有所提高，临界应力强度因子K增加了高达26%。
