(57) [Summary] (with correction) [PROBLEMS] To mass-produce a lightweight, high-strength and ductile structural material at low cost. This lightweight material is also used in automotive structural components such as automotive chassis components and in the building and mechanical engineering. A lightweight material containing lightweight fine particles (particularly mineral-based foamed fine particles) and an organic binder, wherein the volume of the lightweight fine particles in the lightweight material is at least 50%, and the component in the lightweight material is Lightweight material that is structurally tightly bound. In addition, the steps of introducing the lightweight fine granules into the work mold, optionally heating the light fine granule material particles, and introducing the binder into the work mold filled with the lightweight fine bulk material. And a step of solidifying the binder. Furthermore, a composite material comprising a core of lightweight material and a surface consisting entirely of steel, stainless steel, fiber laminate or plastic, which completely or partially surrounds the core. |
