Study of temperature and workpiece damage in drilling of carbon fiber composites

Abstract

The first results of the study of the process parameters of drilling of composites reinforced with carbon fiber (CFRP) used in the aeronautical industry are shown in this work. The analysis uses both cutting forces and temperatures achieved in the drilling process, although it has focused on the application of IR thermography to the study of the drilled 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.
