Abstract
The development of composite-based manufactured parts has been led, by the need of the aerospace industry to reduce the weight of aircrafts while maintaining a very good structural performance. The trend to use thermoplastic instead of thermoset resin enables even lighter parts, nevertheless it involves laser heating instead of IR lamp heating. We describe the development of a laser beam-shaper based on Multi-Plane Line Conversion technology delivering a tailored top-hat beam profile on the composite fiber to optimize its consolidation and therefore final properties. We demonstrate the performance of the process and describe the optical performance of the beam shaper.
