CFRP REPAIR OF IMPACT

This report presents IR thermography results from a series of laboratory experiments conducted on full-scale AASHTO concrete bridge girders Vehicle impact damage was simulated in each girder by cutting four prestressing tendons at midspan An FRP strengthening system was then applied to restore each girder's flexural capacity IR inspections were conducted after each system was installed

On July 12 2006 British-born astronaut Piers Sellers became the first person to conduct thermal nondestructive evaluation experiments in space demonstrating the feasibility of a new tool for detecting damage to the reinforced carbon–carbon (RCC) structures of the Shuttle This new tool was an extravehicular activity (EVA or spacewalk) compatible infrared camera developed by NASA engineers

ITC IR Thermography Primer

Answers to Common Questions People Ask about IR Thermography What is infrared? Infrared energy is part of the electromagnetic spectrum and behaves similarly to visible light It travels through space at the speed of light and can be reflected refracted absorbed and emitted The wavelength of IR energy is about an order of magnitude longer than visible light between 0 7 and 1000 m

Thermography: The Big Picture gets bigger

Modern thermography systems that use signal processing to enhance IR camera performance are based on a four-step excite-acquire-process-analyze inspection sequence The camera must be stationary during acquisition and the duration of acquisition depends on the part's thickness and its thermal properties so there can be a considerable time interval between the start of an area's
