The principle of increasing stiffness of a composite structure by means of sandwich construction is now well established. ROHACELL®, PMI-based structural foam has been used in fiber-composite technology for almost 50 years. And it is by no surprise that ROHACELL® still dominates in the area of high-grade lightweight sandwich construction. ROHACELL®’s success can be attributed to the following:
- Excellent mechanical properties over a wide temperature range, even at low densities
- High temperature resistance up to 210°C
- Unique compressive creep behavior for processing up to 180°C and 0.7 MPa
- Excellent dynamic strength
- Cell sizes that can be tailored for each processing method
The closed-cell foam uptakes resin only in the exposed cut cells at the surface. This prevents excess resin from infiltrating further into the foam, which would add unnecessary weight, and also provides an adequate means of restraining the ROHACELL® by way of vacuum fixation during mechanical processing. ROHACELL® can be processed by common machining methods which include milling, drilling, turning, and sanding. ROHACELL® can also be thermoformed into complex geometries.
