Subsurface Discontinuity Detection in Composites by Infrared Testing

The aerospace and automotive industries are increasingly incorporating the use of carbon fiber materials in structural components. During the manufacture and use of these carbon fiber materials, defects are induced in their structure, so it is important to detect them in time before they end in a catastrophe. One of the most damaging structural defects in carbon fiber laminates that often ends in a catastrophe are delaminations. It is necessary to develop a productive and non-invasive methodology to detect this defect. Analysis of heating and cooling on the surface with an infrared camera may be an option.
