During the award ceremony held at the close of the first day of the 1st International Composites Congress, the new, international version of the annual conference organized by the AVK Composites Germany trade organization, Evonik (Essen, Germany) was delighted to capture not one, but two innovation awards for its new Rohacell structural foam for sandwich components. Rohacell captured the prizes in the categories of Innovative Products and Innovative Processes.
Developed by the Resource Efficiency Segment of Evonik, in Essen, the foam was singled out by the jury for its application in production-ready foam cores for sandwich components—a new development called Rohacell Triple F that relies on a manufacturing process known as in-mold foaming (IMF). Sandwich cores for fiber composite parts are currently designed primarily as flat structures. The new process enables the production of complex, three-dimensional structural cores for industrial-scale CFK sandwich components that display both extreme strength and good temperature resistance. As a result, the cores can also be used in efficient curing processes, such as high-pressure RTM or wet impregnation.
