Repair of composite structures

Composite structures can be repaired almost always without any loss in strength and appearance. The limits mostly defined by the cost-benefit ratio. Due to our knowledge of the materials used, the manufacturing processes and repair techniques enables us to estimate the repair cost and work out quotes for the repair of nearly all components. It is irrelevant whether they are aircraft, boats, car body parts or sports equipment.

Repair of ultralight aircraft (UL,LSA, ELA)


Structure and surface of ultralight aircraft (LSA and ELA included) are - due to their special design "delicate" and thus more sensitive than any "normal" aircraft or glider. A repair therefore requires the most careful application of known repair methods or - in some cases - special solutions to restore the structure without or with minimum weight gain.

Front repair of fuselage/firewall

In case of strong damage to structural components, such as in this case, the fire wall, A-columns and the front part of the belly, the damaged structures can be removed and replaced by a large number of complete new parts or fragments. Through the proper connection of the old and new parts by these repairs result components with the same properties as the original.

Repair of landing gear and main bulkhead CTsw

After a landing accident in which the strut was bent first backwards and pulled down afterwards, the main bulkhead and the the fuselage structure behind it has been damaged. By repairing the main bulkhead with replacement of mounting bushings for the gear strut and partial replacement of the the fuselage shell in the area of the luggage compartment, also this aircraft could be repaired.

Repair of stabilizer mount CTLS

The repair methods described earlier are also applicable to structural strongly stressed points. This includes the stabilizer mounting points. In this case, the right bearing point of the horizontal stabilizer was  so badly damaged during a maneuver at the hangar, that the area had to be replaced completely.

Partial repair of firewall and belly CT

Resulting from nose wheel landings or taxiing against obstacles often the nose wheel strut and the engine frame is bent, causing firewall damages and damages at the lower attachment points of engine mount and the lower fuselage. By restoring structures in the center tunnel and belly area, this area receives back its old strength.

Glider and motorglider / self launching glider


Modern gliders and motorized gliders are also produced mainly in fiber composite construction. The higher effort in these repairs makes the need of compliance with all regulations, because they are certified aircraft. Through a well-organized network of certified aircraft maintenance companies and inspectors, we are to be able to meet most of our customers requirements

Spoiler / Bumper / Car body parts


For the repair of components made of fiber composites as bumpers and spoilers of sports cars, we use high-quality, specially selected resin-hardener systems to provide quality service and to ensure high dimensional stability and durability. Repairs like these we check in advance on the feasibility. Most of these are only useful in the repair of high-quality components, rare sports cars or vintage cars.

Kinetic sculpture „Odin“


Also artwork such as the kinetic sculpture "Odin" at the "Britzer Garten" Berlin using composite materials in order to achieve an optimum combination of high strength combined with low weight. This wind chime, designed and built by artist Sebastian Heinsdorff for a garden festival in Berlin in 1985, is under our care since 2006 and was continuously maintained and repaired. The base structure is made ​​of carbon fiber tubes in a lattice structure. This was originally covered with cotton fabric Since 2006 it´s new covered with translucent painted Ceconite (polyester fabric).
