Single-walled carbon nanotubes theoretically possess ultimate intrinsic tensile strengths in the 100-200 GPa range, among the highest in existing materials. However, all of the experimentally reported values are considerably lower and exhibit a considerable degree of scatter, with the lack of ...
Carbon nanotubes have a variety of structures with various carbon atom alignments. Depending on the number of concentric layers, carbon nanotubes are classified as single-walled or multi-walled nanotubes (Fig. 1b). Additionally, structures of the concentric layers are specified by diameter a...
carbon nanotubes are classified as single-walled or multi-walled nanotubes (Fig. 1b). Additionally, structures of the concentric layers are specified by diameter and chiral angle (Fig 1c) or a pair of integers (n, m) known as chiral indices. ...
Carbon nanotubes (CNTs) are one of the strongest known materials. When assembled into fibres, however, their strength becomes impaired by defects, impurities, random orientations and discontinuous lengths. Fabricating CNT fibres with strength reaching that of a single CNT has been an enduring challeng...
carbon nanotubesIn this work, carbon nanotubes of 0.5 and 1% by weight were added for the first time in a fly ash cement system to produce carbon nanotubes鈥揻ly ash composites in the form of pastes and mortars. Compressive strengths of the composites were then investigated. It was found ...
After the reflow process, isothermal aging study was conducted on the solder/Cu joints and the single-lap solder joint system at 170掳C for time intervals of 500h, 1000h and 1500h. The melting temperature results indicated that the presence of carbon nanotubes addition to the solder matrix ...
High-strength carbon nanotube fibre-like ribbon with high ductility and high electrical conductivity 来自 Semantic Scholar 喜欢 0 阅读量: 466 作者:JN Wang,XG Luo,T Wu,Y Chen 摘要: Macroscopic fibres made up of carbon nanotubes exhibit properties far below theoretical predictions and even much ...
In this paper different deterministic and statistical models, based on new quantized theories proposed by the author, are presented to estimate the strength of a real, thus defective, space elevator cable. The cable, of ~100 megameters in length, is composed by carbon nanotubes, ~100 nanometers...
Yarn‐Like Carbon Nanotube Fibers A fiber made of carbon nanotubes is shown to resemble a conventional yarn in terms of its structure, composed of discrete fibrillar sub-units, and its prop... JJ Vilatela,AH Windle - 《Advanced Materials》 被引量: 179发表: 2010年 Composite Yarns of Mul...
Graphistrength® multi walled carbon nanotubes significantly improve the mechanical strength of composites. Graphistrength® helps to achieve remarkable electrostatic dissipation (ESD) properties at very low concentration rates compared to the filler
