Abstract

The use of infrared photon detectors for full-field measurement of surface temperature for damage assessment of composites is an ongoing field of research. This paper presents the preliminary work on the application of Telops Fast m3K infrared camera for strain energy release rate measurement in fibre failure of carbon fibre composites. The technique is shown for quasistatic loading of compact tension specimen and identifying the crack propagation and instantaneous crack lengths using local changes in temperature near the crack tip.
