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 method for placing a composite ply on a substrate comprising:
- positioning a compaction roller against said substrate to define a nip therebetween;
- scanning a beam of electromagnetic radiation proximate said nip, said beam comprising an optical power, a pulse frequency and a scan speed;
- while said beam is being scanned, varying at least one of said optical power of said beam, said pulse frequency of said beam and said scan speed of said beam to obtain a desired heating profile proximate said nip;
- and
- passing said composite ply through said nip.
