ROHACELL® – the high‑performance foam for aerospace and aviation
New designs in aerospace and aviation are increasingly replacing conventional metal structures with innovative and lightweight high‑performance fiber composites.
Our product line of high‑performance foam core materials for sandwich‑design composites meets the demanding requirements of several structural applications.
Whether for wings, landing gear doors, radomes, or many other exterior components, ROHACELL® provides the right core solution.
CRITERIA FOR SELECTING THE MOST SUITABLE DESIGN AND FOAM
In the area of high‑performance fiber composites, sandwich structures are the preferred choice for lightweight yet stiff designs.
Evonik’s high‑performance lightweight foam ROHACELL® enables customers to meet their targets for exterior applications such as access panels, belly fairings, flaps, engine cowlings, landing gear doors, radomes, and wing leading and trailing edge panels.
In helicopters, ROHACELL® is used in components such as main rotor blades, horizontal stabilizers, skids, and tail rotor blades.
The next generation of transportation and delivery systems—eVTOL aircraft—will also benefit from robust and durable composite sandwich structures featuring a ROHACELL® foam core on the inside and carbon fiber on the outside.
For aerospace applications, ROHACELL® is the preferred and specified core material for high‑performance sandwich composite structures in launch vehicles, including payload fairings, payload adapter fairings, interstages, nose cones, and thermal protection shields.
