Laser welding of plastics and composite structures

Laser transmission welding can be used reliably to join thermoplastics and fiber-reinforced composites.

 

With laser transmission welding, a large variety of plastics and composite materials can be welded. Also non-similar materials can be joined. The group “Composites” offers welding processes for the following materials and material combinations:

  • Constructional and high-performance plastics
  • Glass-fiber reinforced components with CFRP components
  • CFRP-CFRP joints
  • Thermoset/thermoplastic joints (hot melt gluing, SIPN structures)

Furthermore, the group offers new, innovative laser-based processes for fiber placement.

Welding processes can be analyzed using pyrometry, thermography and NIR and VIS cameras.
