A study on the influence of drilling and CO2 laser cutting in carbon/epoxy laminates

Composite structure made of thermoset matrix often requires a circular hole to join with a steel or aluminium. Circular holes are introduced into the carbon/epoxy laminates by means of drilling and continuous wave (cw) CO2 laser. In this study, the quality of circular hole produced by drilling and l...
