AREAS OF APPLICATION
In aviation, the CFRP sandwich rods are used in lightweight trusses, as fixed struts and as movable control rods because of their high specific stiffness and strength.
The trusses used as frames in the new Zeppelin NT are made of the very lightweight yet very rigid CFRP sandwich rods. These lightweight rods are also used as control rods in motor gliders, aerobatic aircraft and various gliders.

SPECIAL PROPERTIES
TYPICAL AREAS OF APPLICATIONS
PROJECT EXAMPLES
CFRP sandwich rods are used in aerobatic aircraft, motor gliders and various gliders. They are significantly lighter than equivalent control rods made of aluminum. Due to the higher buckling length associated with the stiffness, savings can often be achieved in addition to the rod weight by eliminating bearing points.
CFRP sandwich bars are ideally suited for tie rods in aircraft. Due to the very high weight-related stiffness and the associated long buckling length, even distant attachment points can be connected in a weight-optimized manner with high load-bearing capacity. The combination of graduated construction lengths and end pieces of varying length creates a modular system that can cover a wide range of lengths without the need for further cutting. This is particularly beneficial for individual cabin interiors where the required tie rod lengths are not always fixed from the outset.
The trusses used as frames in the Zeppelin NT are made of CFRP sandwich bars, which are significantly lighter than corresponding aluminum tubes. The tubes required for this purpose, with a length of up to 11m, are manufactured continuously without separation points.
