Improved Quality of Drilled Holes in Laminated Carbon Fiber Reinforced Plastics via Laser-Preprocessing

Abstract

In this paper, a new hybrid process to manufacture holes in laminated carbon fiber reinforced plastics is presented. It combines the advantages of conventional drilling (fast and easy to control) and laser drilling (high entry and exit quality of the holes). It is shown, that considerable improvements of the quality of drilled holes can be achieved via laser-preprocessing.
