  • Strength
  • Durability and resistance to damage
  • Lightness
  • Dimensionally stable

DuFLEX® panels are specially designed to reduce construction time and optimize the weight of high-performance composite structures. Time-consuming lamination and vacuum bagging steps normally required to manufacture high-performance composites are avoided, and material waste, labor and tooling costs are significantly reduced. They allow you to focus on your high value-added work.  

DuFLEX® panels are 2400 mm x 1200 mm with multi-axial fiberglass or carbon fiber skins (upon request), laminated with a high-performance epoxy resin.  Fiber orientation and bending schedules are based on design or engineering specifications to best meet weight and strength objectives, stress and impact loads, and other design parameters.

All laminates are finished with peel plies to protect the laminate from contamination and to reduce surface preparation prior to bonding or application of paint or other materials.

Balsa wood standing timber has an extremely high strength-to-weight ratio, excellent mechanical properties, good thermal and sound insulation properties, high impact and fatigue resistance and good moisture resistance.

Typical applications include hulls, decks, superstructures, bulkheads, frames and stringers in single construction, prototypes and electrical outlets. Non-marine applications include floors, walls, doors, roofs and interior partitions of railways, automobile floors and truck bodies, and long span architectural roofs and partitions.

Connection between panels: Z-joint (scarf cut option)
DuFLEX® panels can optionally be supplied with both long and/or short edges pre-machined for easy assembly. The Z-joint provides a smooth and even surface profile. The Z-joint must be glued after impregnation with a mixture of epoxy glue and WS409 filler.

Choose the scarf cut option:
If you wish to have a scarf cut in order to facilitate the gluing of the panels, you can choose whether you want the cut in length or width and the number of cuts you want.

Option cutting of the panels in numerical control :
If you wish to receive your panels pre-cut to your dimensions, you can select this option. You will have to provide us with your plans by email at in DWG format. Please allow 4 to 5 weeks for delivery.
