In this study, the graphene nanoplates (GnPs) and carbon nanotubes (CNTs) are simultaneous deposited on carbon fiber (CF) surface by fiber sizing method. The synergistic effect between GnPs and CNTs in increasing the interfacial and mechanical properties of carbon fiber reinforcement epoxy composites (CFRP) is investigated. The fracture surfaces of the CFRP composites indicated that GnPs/CNTs hybrid coating exhibited the best interfacial and mechanical performance in all coating sample. The interlaminar shear strength of GnPs/CNTs hybrid coated CFRP composites was 90% higher than non-coated CF composites. The flexural and tensile strength of CFRP composites with GnPs/CNTs hybrid coating have an improvement of 52% and 70%, respectively, compared to non-coated CF.
在本研究中，通过纤维上浆法将石墨烯纳米片（GnPs）和碳纳米管（CNTs）同时沉积在碳纤维（CF）表面。研究了GnPs和CNTs在提高碳纤维增强环氧复合材料（CFRP）界面和力学性能方面的协同效应。CFRP复合材料的断裂表面表明，在所有涂层样品中，GnPs/CNTs混合涂层表现出最佳的界面和力学性能。GnPs/CNTs混合涂层CFRP复合材料的层间剪切强度比未涂层CF复合材料高90%。与未涂层CF相比，具有GnPs/CNTs混合涂层的CFRP复合材料的弯曲强度和拉伸强度分别提高了52%和70%。
