Infrared thermography to monitor Glare ® under cyclic bending tests with correction of camera noise

The capability of infrared thermography, to visualize thermoelastic effects developing in fibre reinforced composites under cyclic bending, has already been demonstrated through handy-load tests. The manual application of the load poses some problems such as the impracticality to change the load frequency and the overall test accuracy. The intention of the present paper is to carry out this investigation on fibre reinforced metal laminates by using a testing apparatus which allows power-driven load application with changing of the bending frequency. In this work, also the IR camera imaging frame rate is varied to look for the optimal value to perform tests in a quick and reliable way. Besides, a correction of the instrument and environmental noise is proposed and tested.
