Plastic-bound lightweight materials, method for the production thereof, and composite materials

Abstract

The present invention relates to lightweight materials which contain lightweight granules, in particular mineral foam granules, and an organic binder, the volume amount of the lightweight granules in the material being at least 50%, and that the components are bound in the material in a structurally dense manner. Furthermore, the invention relates to a method for the production thereof by the following steps: introducing the lightweight granules into a workpiece mold, optionally heating the grain feed of lightweight granules, introducing the binder into the workpiece mold filled with the lightweight granular bulk material, solidifying the binder, and to a composite material containing a core of the lightweight material according to the invention and a surface surrounding the core completely or in part and consisting of steel, stainless steel, fiber laminates or plastics.
