ROHACELL 110 WF: First Choice for Aeronautic and Aerospace Applications

Material Notes:
ROHACELL WF has been designed for use primarily in aerospace applications; in addition to conforming to our material specification sheet, it satisfies the usual industry requirements such as MIL and CMS specifications.

ROHACELL WF goes, for example, into the body panels of Boeing’s Delta II, III, and IV rockets. Its outstanding properties are brought to bear in such aircraft structures as the stringer structures in the pressure bulkheads of the Airbus A380 and A340. This structural foam is also suitable for helicopter applications, for example, in the main and tail rotor blades, as well as in fuselage panels; it is used by Eurocopter, Bell, Westland, and Sikorsky, among others.

ROHACELL WF rigid foam can be processed at pressures of up to 0.7 MPa and temperatures of up to 130°C. It is therefore highly suited for autoclave prepreg processing and all typical resin infusion processes. After heat treatment, ROHACELL WF can even tolerate curing temperatures of 180°C at a pressure of 0.7 MPa.

The minimal material properties are mentioned in the “Werkstoffleistungsblatt WL 5.1461” of DIN.
