Abstract: A disclosed process includes steps of heating a foamed material by irradiation with near infrared radiation having a wavelength between 0.78 and 1.40 μm to form a heated material, forming the heated material with a forming tool to obtain a formed material, and cooling the formed material and demolding to obtain a final workpiece. The foamed material may be constructed as a composite ply construction including an outer material and a foamed core between the outer material. The foamed material may contain a poly(meth)acrylimde, a polypropylene or a highly-crosslinked polyurethane.

Abstract: The invention describes a method for producing a foam molding from poly(meth)acrylimide, an adhesion promoter or an adhesion promoter mixture and optional auxiliaries, comprising the following steps: grinding a polymeric molding made of poly(meth)acrylamide, coating the grindings obtained in the preceding step with an adhesion promoter, introducing the coated grindings into a mold, optionally adding the auxiliaries, heating the mold, cooling the mold below the foaming temperature, and demolding the foam molding. The resulting foam molding has outstanding mechanical properties and is suitable for applications including as a component in the production of space, air, water and land vehicles.
