We give the king of the skies a smooth ascent
The Airbus A380 is an imposing sight. What you can't see is that this giant passenger aircraft, weighing more than 500 metric tons, is subjected to extremely high mechanical stresses both in the air and at takeoff and landing. Sandwich components made with ROHACELL® contribute to the necessary stability—and, at the same time, the minimum possible weight.
A super-strength lightweight
Hard foam developed by Evonik is used in aircraft construction to produce a variety of highly stable and extremely durable components by means of advanced lightweight construction methods. ROHACELL® is entirely unaffected by temperature fluctuations—an important prerequisite for aircraft, which can be exposed to temperature differences as great as 100 degrees.
First-rate properties for a broad application spectrum
ROHACELL® is a high-strength polymethacrylimide hard foam combining unsurpassed mechanical
properties with low weight. ROHACELL® is used as a core material in what are known as sandwich
structures, where the foam is usually combined with carbon fiber-reinforced surface layers. Evonik
has developed ten different kinds of ROHACELL® to meet a large number of different requirements on
land and water and in the air.
But ROHACELL® is used for more than streamlining aircraft, helicopters, high-speed trains,
and top-speed catamarans. It is also an invisible component of speakers and antennae, and patient
tables for x ray machines. ROHACELL® is also the material of choice for particularly light and
stable racing bikes and skis. It improves the crash behavior of the front end of regional trains
and makes car body parts 70 percent lighter—which is of interest not only for Formula 1 racing
cars, but now also for mass-produced vehicles with lightweight construction.
