A half closed thermoplastic folded honeycomb structure is described which is produced from a continuous web of material by plastic deformation perpendicular to the plane of the material to thereby form half-hexagonal cell walls and small connecting areas. By folding in the direction of conveyance the cell walls meet to thereby form the honeycomb structure.

A protective helmet is described comprising: an outer layer (); an inner layer () for contact with a head of a wearer; and an intermediate layer () comprising an anisotropic cellular material comprising cells having cell walls, the anisotropic cellular material having a relatively low resistance against deformation resulting from tangential forces on the helmet. The anisotropic material can be a foam or honeycomb material. The foam is preferably a closed cell foam. The helmet allows tangential impacts to the helmet which cause less rotational acceleration or deceleration of the head of the wearer compared to helmets using isotropic foams while still absorbing a significant amount of rotational energy.

This invention consists of a modified gluten biopolymer for use in industrial applications, such as composites and foams. In the present work, the fracture toughness of the gluten polymer was improved with the addition of a thiol-containing modifying agent. This work also resulted in the development of a gluten biopolymer-modified fiber bundle, demonstrating the potential to process fully biodegradable composite materials. Qualitative analysis suggests that a reasonably strong interface between the natural fibers and biopolymer matrix can form spontaneously under the proper conditions. Therefore this invention relates to a modified gluten biopolymer for use in industrial applications, such as composites, stabilized foams and molded articles of manufactures. The present invention relates to a new gluten based biopolymer with modified properties, such as an increase in impact strength, and prepared by using thiol-containing molecules. The multifunctional activity of the polythiol-containing molecules generates the potential for the development of a new material base for commodity plastics. The invention furthermore relates to a new composite material comprising gluten-coated fiber, its use and the method for preparing the composite material.

The invention relates to a folded honeycomb structure and to a method and device for producing said folded honeycomb structure from a corrugated core web. The folded honeycomb structure has a number of adjacent corrugated core strips which lie in one plane and are interconnected by cover layer strips. Said cover layer strips are folded about 180&deg; and are perpendicular to said plane. According to the inventive method for producing the folded honeycomb structure, interconnected corrugated core strips are produced first by making a number of longitudinal scores in a corrugated core web. These corrugated core strips are then alternately rotated through 90&deg; respectively so that the cover layer strips fold and the folded honeycomb structure is formed. The device corresponding to this method consists of a number of rotating blades for making the longitudinal scores and a number of guiding elements for rotating the interconnecting corrugated core strips.
