摘要
碳纳米管(Carbon Nanotube,CNT)具有非常优异的刚度和强度。CNT增强基体的传统连续纤维多尺度混杂复合材料既具有优良的纤维主导力学性能又有好的基体主导力学性能,具有广泛的应用前景。综述了国内外在碳纳米管增强基体的多尺度混杂复合材料力学性能,制备和数值模拟等方面的最新研究进展。提出了进一步研究需要解决的两个关键问题:(1)量化CNT对传统复合材料的增强效果;(2)阐明CNT对多尺度混杂复合材料的增强机制,并提出了相应的研究手段。
Carbon nanotubes(CNT)possess exceptional stiffness and strength.CNT and conventional continuous fiber reinforced matrix multiscale hybrid composites not only has excellent fiber-dominated mechanical properties but also possesses eximious matrix-dominated properties.The research status on the carbon fiber/CNT-matrix multiscale hybrid composites was reviewed,included the mechanical properties,preparation and the numerical researches.Two key issues was proposed to address the further study:(1)quantization of the reinforced effect of CNT to the conventional composites,(2)clarification of the reinforced mechanisms of CNT in the composites.
