Evaluation of bore exit quality for fibre reinforced plastics including delamination and uncut fibres

Analyses of the bore exit in Carbon Fibre Reinforced Plastics (CFRP) represent a common method to evaluate workpiece quality non-destructively. The delamination factor Fd, developed by Chen (International Journal of Machine Tools and Manufacture, 37 (1997) 1097) has been established, being a straightforward measureable variable representing the bore quality. Within this paper the advantages and disadvantages of the delamination factor Fd, the...
