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

The propeller blades are made from several layers of woven glass and carbon fibre,
reinforced with different sorts of glass and carbon fibre tapes. These are connected with a
glass fibre reinforced expanding epoxy resin in "wet in wet procedure" with each other. The
internal power transmission decisive for the firmness between the top and underside of the
sheet is therefore over the entire surface. From this construction method a good vibration
damping as well as insensitiveness results with damages by external effect.
The leading edges are protected normally by a PU-adhesive-tape against water effect.
Optionally a metallic edge protection of nickel cobalt can be applied for the protection.
Also optionally a lightweight construction with 3-D distance fabric is used instead of the
construction method with expanding epoxy resin. A high stiffness and firmness guarantees
this with at the same time low weight.
