Approach to the Study of Workpiece Damage in Drilling of Carbon Fiber Composites by Using Thermography IR

Abstract

The present work shows the first results of the study methodology of the process parameters applied to drilling of composites reinforced with carbon fiber (CFRP) used in the aeronautical industry. The analysis uses both cutting forces and temperatures achieved in the cutting process, although it has focused on the application of IR thermography to the study of the hole. The study of the defects that can be found on the workpiece, associated with these processes (delamination), is approached by using both optical microscopy and SEM.
