Drilling technique for carbon fiber reinforced thermoplastic (CFRTP)
- Technical Classification:
- [ Processing ]
- Products:
- [ Service ]
- Keyword:
- [ Carbon fiber reinforced thermoplastic ] [ CFRTP ] [ drilling ] [ Step drill ]
Point of the Proposed Technology
CFRTP materials shows ductile behavior in a drilling process in contrast with CFRP with thermosetting resin, and it causes a problem of large burr remaining at the drilled hole end using a conventional twist drill. In order to prevent large burr growing, we have proposed “a step drill” that distributes the cutting force for the work plate in drilling.
Effect(s)
Improvement of the drilled hole quality of a CFRTP material (burr reduction)
