Composite materials have become integral to industry, used in aviation and space technologies, as well as auto manufacturing and mining. However, internal stress assessment with composite material designs has long been challenging. Scientists from the NUST MISIS Center of Composite Materials, led by Professor Sergey Kaloshkin, have now proposed a non-contact method of internal voltage control in polymer composites. The researchers report that it is now possible to more effectively assess the degree of internal damage during the operation of aircraft parts, oil pipelines, ship hulls, and other industrial and transport facilities.
