The atomic structure of carbon fiber is similar to that of graphite, consisting of sheets of carbon atoms arranged in a regular hexagonal pattern (graphene sheets), the difference being in the way these sheets interlock. Graphite is a crystalline material in which the sheets are stacked parallel...
It was concluded that the atomic structure of the fiber resembles the hexagonal structure of graphite. But locally this structure is disturbed. From the modulation of the superstructure it is deduced that this disturbance extends at least two layers into the bulk....
In other methods, the plastic mixture is heated and pumped through tiny jets into a chamber where the solvents evaporate, leaving a solid fiber. The spinning step is important because the internal atomic structure of the fiber is formed during this process. 3 The fibers are then washed and ...
2.3 Carbon fiber Considering that glass fiber has low modulus and heat resistance is not enough, it is difficult to meet the requirements of structure application in aerospace industry. In the 1960s, carbon fiber, boron fiber and other fiber materials with high-strength, high modulus and low-de...

carbon fiber having a crystal structure characterized by specific X-ray structure parameters comprising an orientation angle of 25-38 deg., a lamination thickness of 19-35Angstrom and a plane spacing of 3.45-3.50Angstrom and having an O/C atomic ratio of 0.1-0.35 on the fiber surface ...
In the first step of this research, the structure of concrete is simulated, and the thermodynamic equilibrium in this structure is investigated. To investigating the thermodynamic equilibrium in this atomic structure, physical properties such as the temperature of the simulated system and the energy of...

In contrast with CNTs, the graphite layers in nanofibers (graphitic filamentous structures) are arranged either perpendicular to the fiber axis or at an angle to it [171,185]. Carbon nano-fibers (CNFs) with more disordered, less oriented structure and more defects could increase the reversible ...
[146] made an attempt and fabricated binder-free carbon fiber aerogel and reported good specific capacitance around 283 Fg−1 with a constant electrical conductivity of approximately 860 Sm−1. In another study, Miao et al. [147] also used biomass like Peng et al. [146] to derive ...
