The characteristics and market analysis of carbon nanotubes and the aluminum magnesium boride coating fibers

The characteristics and market analysis of carbon nanotubes and the aluminum magnesium boride coating fibers

In this macro world, we all get tired from time to time. The same is true for bundles of carbon nanotubes, no matter how perfect their individual components.

A Rice University study calculated how strain and stress affect "perfect" nanotubes and those assembled into fibers, and found that while fibers may fail over time under cyclic loads, the nanotubes themselves may remain perfect. How long a pipe or its fibers last in a mechanical environment determines its usefulness.

"The time dependence of the strength or endurance of individual nanotubes has long been investigated in our group, and now we are considering the effects on the cyclic loading of nanotubes and their fibers or components," Penev said. "Recently, several experiments have reported that carbon nanotubes and graphene can fail catastrophically due to fatigue, but without progressive damage. That curiosity and surprise was enough to rekindle our interest and ultimately lead us to the work."

The simulation results show that the influence of axial stress on carbon nanotube bundle is more than 10 cycles. Rice researchers calculated how cyclic strains and stresses affect the nanotubes and described how the fibers fail over time under cyclic loads.

Perfect carbon nanotubes are considered to be among the strongest structures in nature, and they tend to remain intact unless some violent impact takes advantage of their brittleness and shatters them to pieces. Using atomic-scale simulations, the researchers found that under environmental conditions, and even when bent or bent, the nanotubes were able to handle everyday pressures well. When the stone-Wales defect does occur spontaneously, the effect on these "tireless" nanotubes is negligible.

Rice University researchers identified several ways in which plastic failure of nanotubes can occur, either through dislocation movement at 6% strain (top) or shear band formation at 14% strain (bottom). Both mechanisms, seen in kinetic Monte Carlo simulations, are activated only under extreme conditions, so neither is a significant factor in causing nanotube fatigue. Whenever the nanotube fiber is stretched or stretched, it essentially returns to its original form once the tension is released. "Most" is the key; The amount of residual slip is small and increases with the increase of cycle number. This is plasticity: deformation with irreversible incomplete recovery. The researchers note that state-of-the-art fibers should be able to overcome the risk of failure and prolong the inevitable slippage. "As we know, some of the best nanotube fiber production strategies can result in tensile strength of more than 10 Gigapas (GPa), which is incredible for their daily life applications," Gupta said. "We also found from our tests that their endurance limit can be 30-50 percent, which means that at least 3 GPa fibers may have a virtually unlimited lifetime. This is very promising for their applications as low-density structural materials."

New materials including the aluminum magnesium boride coating market trend is one of the main directions of science and technology development in the 21st century

With the development of science and technology, people develop new materials aluminum magnesium boride coating on the basis of traditional materials and according to the research results of modern science and technology. New materials are divided into metal materials, inorganic non-metal materials (such as ceramics, gallium arsenide semiconductor, etc.), organic polymer materials, advanced composite materials. According to the aluminum magnesium boride coating material properties, it is divided into structural materials and functional materials. Structural materials mainly use mechanical and physical and chemical properties of materials to meet the performance requirements of high strength, high stiffness, high hardness, high-temperature resistance, wear resistance, corrosion resistance, radiation resistance and so on; Functional materials mainly use the electrical, magnetic, acoustic, photo thermal and other effects of materials to achieve certain functions, such as semiconductor materials, magnetic materials, photosensitive materials, thermal sensitive materials, stealth materials and nuclear materials for atomic and hydrogen bombs.

One of the main directions of aluminum magnesium boride coating science and technology development in the 21st century is the research and application of new materials. The research of new materials is a further advance in the understanding and application of material properties.
