Abstract
A fiber placement system including a compaction roller rotatable about an axis of rotation, the compaction roller at least partially defining a compaction nip region, and a laser heating assembly including a laser that emits a beam of electromagnetic radiation and a scan head defining a scan field, the scan field being aligned with the compaction nip region, wherein the scan head scans the beam within the scan field.
Claims20
A fiber placement system comprising:
- a compaction roller rotatable about an axis of rotation, said compaction roller at least partially defining a compaction nip region;
- and
- a laser heating assembly comprising:
- a laser that emits a beam of electromagnetic radiation;
- a scan head defining a scan field, said scan field being aligned with said compaction nip region, wherein said scan head scans said beam within said scan field to vary a location of said beam in said compaction nip region, and wherein said scan head comprises a galvo assembly comprising at least one galvanometer device, wherein said galvo assembly receives said beam emitted by said laser and varies a location of said beam in said scan head;
- and
- a controller configured to control said galvo assembly to scan said beam while varying at least one of a speed at which said galvo assembly of said scan head scans said beam, an optical power of said beam and a pulse frequency of said beam to obtain a desired heating profile within said compaction nip region.
