The nanotubes, having an extreme small physical size (diameter ≈1 nm) and many unique mechanical and electrical properties depending on the hexagonal lattice arrangement and chiral vector have been appreciated as ideal fibres for nanocomposite structures. It has been reported that the nanotubes have remarkable mechanical properties with theoretical Youngs modulus and tensile strength as high as 1 TPa and 200 GPa, respectively. Since the nanotubes are highly chemical inert and able to sustain a high strain (10-30%) without breakage, it can be foreseen that nanotube-related structures could be designed for nanoinstruments to create ultra-small electronic circuits and used as strong, light and high toughness fibres for nanocomposite structures. In this paper, recent researches and applications on carbon nanotubes and nanotube composites are reviewed. The interfacial bonding properties, mechanical performance and reliability of nanotube/polymer composites are discussed 关键词: carbon nanotubes;composite material interfaces;composite materials;electric properties;mechanical properties;reviews;tensile strength;Youngs modulus;carbon nanotube composites;advanced materials;extreme small physical size;diameter;electrical properties;mechanical properties;hexagonal lattice arrangement;chiral vector;ideal fibres;nanocomposite structures;Young modulus;tensile strength;highly chemical insert;nanotube-related structures;nanoinstruments;ultra-small electronic circuits;high toughness fibres;strong light fibres;nanotube composites;interfacial bonding properties;mechanical performance;reliability;nanotube/polymer composites;C
