Composites resist very high dynamic and thermal stress for a long time. They are virtually undestroyable by chemicals. All of the above has been demonstrated since the 1950's in hundreds of thousands of boats and airplanes or gliders. The rigid material made from Composites is extremely durable and not subject to fatique or corrosion. It needs hardly any maintenance, and is easy and quick to repair.
Composites have a precise surface and show clean workmanship up to the smallest detail.
Another advantage of composites is the tightly pressurized cabin, the watertight fuselage and the ressistance against saltwater. All antennas are protected due to internal mounting.
