Abstract: Prestressed carbon fibers of at least one textile structure comprising carbon fibers are embedded in a concrete matrix. At least one textile structure comprising carbon fiber bundles is laid in a mold at a distance from one another, into two accommodation elements which are arranged at two diametrical end faces of the mold. Hollow spaces within the accommodation element are filled with a rapid-curing viscous composition having a mineral basis or rapid-curing polymer. After curing the composition or of the polymer, tensile forces act on the accommodation element(s) in the longitudinal direction of the carbon fiber bundles with a tensioning device. During the tensile force the interior of the mold is subsequently filled completely with viscous concrete. After curing of the concrete, the tensile forces on the prestressed carbon fiber bundles are largely transferred to the cured concrete and the concrete component can then be removed from the mold.

Abstract: An injection moulding tool for producing at least one injection-moulded part with an outer shape and an inner shape includes at least one cavity and, for every cavity, one hot-runner nozzle connected thereto, which has an annular nozzle mouth for injecting at least one melt into the cavity. The at least one cavity is formed by a cooled die, which forms the outer form for the outer shape of the injection-moulded part to be produced, and by a core, which forms the inner form for the inner shape of the injection-moulded part to be produced. The hot-runner nozzle has a nozzle core and a hollow needle, which can be moved along the nozzle core for opening and closing the annular nozzle mouth. The nozzle core protrudes beyond the annular nozzle mouth of the hot-runner nozzle and the nozzle core forms the core of the cavity of the injection mould.

Abstract: Systems and methods of additive manufacturing are provided, in which solid polymer material in form of strand(s) or particles is continuously received, and its surface is heated peripherally to liquefy the surface, using specified heating-related parameters which are selected to maintain a central volume of the continuously received solid polymer material in a solid state. The surface of a polymer substrate is also liquefied, and the peripherally heated surface of the continuously received solid polymer material is attached to the liquefied surface of the polymer substrate, followed by re-solidification of the liquefied surface to yield monolithic attachment of the material to the substrate. Liquefying only the surface of the material maintains some of its strength and prevents deformation upon solidification. The monolithic attachment provides uniform and controllable industrial products.

Abstract: Embodiments relate to a method of fabricating a nano-sized structure in a resin element by nanoimprint lithography (NIL). The method reduces adhesive failure during NIL demolding by forming a layer of polymerization inhibiting compound at the interface of the resin element and template.

The method includes aging the resin element to promote migration of the polymerization inhibiting compound to an interface of the resin element with air. The method also includes pressing a surface of a template having a nano-sized pattern onto the surface of the resin element exposed to the air to form the nano-sized structure in the resin element. The method further includes curing the resin element after the nano-sized structure is formed and then removing the template from the resin element.
