Researchers in Russia have developed nanostructured sensor made of carbon nanotubes which generates heat under electrical current. When it is embedded in a composite, it leaves the composite’s thickness unaffected, other characteristics unimpaired and does not create undesirable pores. It can serve as a sensor for structural health monitoring or a heater for anti-icing or de-icing purposes. By applying an electrical current to the carbon nanotube layer and monitoring the signal, it is possible to keep track of the structure’s deterioration and avert disaster by anticipating breakage. Electricity can also be used for heating to de-ice an aircraft wing or a wind turbine blade. The material can be manufactured using heat and cured without using autoclave. Embedding carbon nanotubes does not increase the thickness of the composite, or porosity. The mechanical properties are improved not compromised…read more. Open Access TECHNICAL ARTICLE
