Abstract Plates of honeycomb structure, that are made, for example, from polyamide paper, are used as core material for sand- wich boards with covering layers of carbon or glass fibre rein- forced plastics or of aluminium. The new light-weight construction material is to be used for manufacturing honeycomb structures which, in comparison to the known honeycomb structures, are characterized by higher strength and stiffness, improved energy absorption and improved behavior in fire. The light-weight construction material consists of a fibrous thermoplastic compo- site foil which contains carbon, silicon carbide, whisker or the like fibres in the form of woven fabric, or mats, the fibres being embedded in a matrix of a high temperature thermoplastic such as polyether ether ketone, polyether sulfone or polysulfone. The sandwich boards with honeycomb cores are used in the field of aeronautics and space travel, mechanical engineering, and in the construction of rail vehicles and watercraft as well as of sport and recreational equipment.
