“…They have excellent mechanical properties since individual CNTs possess very high tensile strength in the range from 11 to 63 GPa, tensile Young's modulus of 1.0 to 1.3 TPa, and high ultimate fracture strain of about 10% [8][9][10][11]. Moreover, CNTs are flexible, lightweight, good heat and electricity conductors, thus being useful in a number of applications [12][13][14][15]. The most important mechanical applications of CNTs are high-strength ropes [2,16], fibers [17][18][19][20][21], polymer-and metal-matrix composites [22][23][24], solid lubricants [24,25], etc.…”

Mechanical response of the carbon nanotube bundle to uniaxial and biaxial lateral compression followed by unloading is modeled under plane strain conditions. The chain model with a reduced number of degrees of freedom is employed with high efficiency. During loading, two critical values of strain are detected. Firstly, period doubling is observed as a result of the second order phase transition, and at higher compressive strain, the first order phase transition takes place when carbon nanotubes start to collapse. The loading-unloading stress-strain curves exhibit a hysteresis loop and, upon unloading, the structure returns to its initial form with no residual strain. This behavior of the nanotube bundle can be employed for the design of an elastic damper.

“…Therefore, CNT web was utilized as an electro-thermal heating element for anti-icing and deicing of composite structures. Highly aligned CNT-web-heater has negligible weight, quick and uniform heating, economical energy consumption, is compatible with CFR, and can be tuned both in terms of shape and performance to suit any surface and power requirement to achieve rapid deicing (Yao et al 2018, Molnár et al 2014. Yao et al (2018) investigated improved anti-icing and deicing systems made of highly aligned carbon nanotube webs.…”

There are many problems facing aircraft in the air during flight, such as lightning strikes and ice accumulation on aircraft surfaces. These problems usually reduce aircraft efficiency and lead to serious accidents and fatalities. However, the current protection systems used to solve these problems of aircraft represent excessive energy usage, a hazard to the environment, and they are generally bulky, heavy and costly. Therefore, there are new conductive composites containing an embedded layer of conductive fibers such as graphene and carbon nanotube designed to carry lightning currents, in addition to that, there is a new deicing heater element made of graphene nanoribbons films to be used in ice protection systems. This paper presents a review of some problems facing aircraft in the air, such as lightning and ice accumulation on the surfaces of the aircraft and the significant efforts that have been exerted to address and solve these issues. Also, this paper reviews the contribution of composite materials in reducing the weight of the aircraft and fuel consumption as well as increasing the efficiency of aircraft. This paper also will review the conductive composite materials and its application for aviation, in addition to their contribution to solving the most important problems in aviation.

“…Directly drawn CNT webs exhibit a uniform highly-aligned network, eliminating the agglomeration challenges encountered when dispersing in bulk resin. As the CNTs are highly aligned in the direction of draw, the resistivity perpendicular to the draw direction is approximately 20 times higher than that parallel to the draw direction [25]. Joints were subjected to quasi-static and cyclic loading tests to investigate the influence of CNT-SLW orientation on the damage sensing and joint performance.…”

Herein, we present a novel approach for damage sensing in adhesively bonded joints using a carbon nanotube single layer web (CNT-SLW) which marks a significant departure from the approach of dispersing CNTs within epoxy resins. In this work, a very thin, highly aligned CNT-SLW (densified thickness ~ 50 nm) with aerial density of 2.0 µg/cm 2 was horizontally drawn from a vertically aligned CNT forest, positioned over an adhesive film, which was, in turn, placed between two non-conductive composite adherents. This was followed by the application of heat and pressure to cure the adhesive. These joints were subjected to quasi-static and cyclic loading to investigate the damage sensing performance of a CNT-SLW. The CNT-SLW sensor, placed parallel to the load direction, exhibits remarkably high cyclic stability as well as exceptionally high sensitivity to damage initiation and accumulation. The resistance increase (∆R/R o % ∼1633%) is significantly higher than that of adhesive sensors with dispersed CNTs/graphene, reported in the literature. Morphological studies help to explain the sensing mechanism through interactions of the CNT-SLW with the evolution of micro-cracks. These results demonstrate the potential of
