Modifying carbon nanotube fibers: A study relating apparent interfacial shear strength and failure mode

Microstructural evolution of carbon nanotube fibers: deformation and strength mechanism.

A comprehensive investigation of the mechanical behavior and microstructural evolution of carbon nanotube (CNT) continuous fibers under twisting and tension is conducted using coarse-grained molecular dynamics simulations. The tensile strength of CNT fibers with random CNT stacking is found to be higher than that of fibers with regular CNT stacking. The factor dominating the mechanical response...

Nanotube Composite Carbon Fibers

The mechanical properties of materials in small rod-shaped form are of considerable technological interest since, due to their shape and size, they can exhibit appreciably greater strength relative to corresponding macroscopic forms. For example, the mechanical strength of silicon carbide whiskers systematically increases with decreasing whisker diameter over the 100 to 1 micron range. This phe...

Anisotropy of Reinforcement Fibres and Its Influence on the Apparent Interfacial Shear Strength in Thermoplastic Composites

Optimization of the stress transfer capability of the fibre-matrix interphase region is critical to achieving the required performance level in thermoplastic matrix composites. Despite the ever increasing diversity of the reinforcements available for polymer composites, glass fibres still account for 95% of fibre reinforcements used in the composites industry, primarily due to of their highly a...
