Description
HELIX propeller have been built since 1990 using composite materials such as
carbon fibre, epoxy-resin, epoxy resin foam and aluminium.
This combination of materials provides:
- High Thrust
- Low Noise
- Durability

2.1 Blades
The Propeller Blades are made from several layers of woven carbon fibre,
reinforced with different sorts of carbon fibre tapes. They are bonded with epoxy
resin foam reinforced by glass fibre. This method of construction which ensures
that the load is distributed throughout the whole surface of the Blade and
dissipates vibration.
At voluminous profile series optionally a construction method with three-
dimensional-fabric instead of epoxy resin foam is used. This construction method
guarantees a low weight combined with high strength and rigidity.
