Thermochromism refers to the phenomenon where a material undergoes color changes under temperature changes. This change is usually caused by changes in the electronic or molecular structure of the material. Its application principle mainly involves t...
Carbon nanotubes for strengthening composite materials(metal matrix,ceramic matrix,polymer matrix composite)
Carbon nanotubes (CNTs), with their high strength, modulus, large aspect ratio, and light weight, seem to be the ideal reinforcement fiber for composites.
Carbon nanotubes can occur as multiple concentric cylinders of carbon atoms, called multi-walled carbon nanotubes (MWCNTs). Logically carbon nanotubes that have only one cylinder are called single-walled carbon nanotubes (SWCNTs). Both MWCNT and SWCNT are used to strengthen composite materials,ceramic matrix,polymer matrix composite.
CNT-ceramic composites become attractive materials not only for their enhanced mechanical properties, but also for the possibility to tailor the electrical conductivity through the CNT content.
by the higher aspect ratio of the CNT. And the composites containing more than 2 wt% CNT exhibited non-Newtonian curves at low frequency.
The properties of carbon nanotubes have caused researchers and companies to consider using them in several fields. For example, because carbon nanotubes have the highest strength-to-weight ratio of any known material, researchers are combining carbon nanotubes with other materials into composites that can be used to build lightweight spacecraft.
