Isotropic behaviour
ROHACELL® WF exhibits high thermal and mechanical properties in all three dimensions, eliminating the need for potting or reinforcements.
Reduced weight
The closed-cell structure ensures resin stays in the interface between the core and face sheet, reducing unnecessary weight and lowering component weight by up to 20%.
Processing compatibility
Highly suitable for autoclave technologies and vacuum infusion processes, including RTM and VARTM. After heat treatment, it can withstand curing temperatures of 180 °C.
