Heating fibers with laser energy

Schenectady, N.Y. – Automated Dynamics is testing the use of a laser-based heating method for the production of fiber-placed composite materials.

The laser-based heating method is currently being integrated into Automated Dynamics’ fiber placement technology and will be used to replace and/or supplement hot gas for heating.

"This new heating process will help us improve control over temperature in the bond zone and lead to greater efficiency," said Robert Langone, president. "We look forward to using lasers for parts production in the near future and plan to make them available as an option on sales of our composite processing equipment as well. Of particular interest is the boost in processing speeds and associated gains in material throughput and consolidation quality that preliminary work with this form of energy delivery is demonstrating."

According to Automated Dynamics, laser benefits include: improved process control, greater productivity, improved reliability and high electrical efficiency.

Automated Dynamics say it purchased the laser from IPG Photonics and the effort is being partially funded with support from New York State Energy Research and Development Authority.
