Princeton Junction, NJ – Oct. 20, 2009 – MISTRAS Group, Inc. (NYSE:MG), announces Line Scanning Thermography (LST), their latest thermography technique for non-contact inspections of metallic and advanced composite materials.
Developed by a major national air and space facility and refined by MISTRAS Products and Systems, LST is capable of inspecting large areas, without loss of resolution, in a reduced amount of time due to the dynamic heat application used with the system. This technique allows LST to inspect layer bonding in advanced laminate composites, changes in material thickness, impact damage and the presence of inclusions or cavities inside structural components.

“In a short amount of time, we have been able to successfully turn the LST into a thermography technique for the scanning of advanced aerospace and other composites,” said Obdulia Ley, PhD, Research Scientist at MISTRAS Products & Systems. “With this success, we are confident to continue our work with this method, along with introducing a 2nd generation inspection system to be used by the U.S. Navy for laminate composite testing.”

The LST technique has also been used to provide a measurement of tube thickness and to detect regions of thinning in boiler tubes. This approach can be applied to a variety of materials such as fiber reinforced plastics, concrete surfaces and any materials that will react to dynamic heat absorption.
