Drilling CFRP Thermosets Using Mounted Points

Abstract:

Article Preview

Highly abrasive nature of carbon fibres and material-related problems like fibre or fibre bundle pullouts, matrix micro cracks and especially delamination of single or multiple laminate layers can be regarded as major problems when machining CFRP. This paper presents an approach using mounted points for drilling of fibre reinforced thermosets. The axial and thermal loads were recorded and quality criterions like the surface roughness, diameter deviation and the delamination at the tool exit side were quantified. Furthermore, an approach to improve the grinding process is presented. Results indicate that using mounted points are suitable for drilling operations in case of thermoset laminates.
