Infrared signatures of bonded interfaces for the repair of primary structures in composite materials

Abstract : This paper deals with the use of infrared thermography for the reliability evaluation of bonded repaired composite structures. To address such issue, the present work intends to characterize a heat flow load by inverse identification. In this way, a specific experimental bench is developed to carry out thermal tests under controlled conditions. Moreover, the FEMU technique is adopted to identify the heat flow amplitude by means of correlation between experimental and numerical surface temperature fields. Such procedure is used on metallics coupons to identify the heat flow and is validated on carbon fiber laminates with different lay up.
