  • Patent number: 11691926
    Abstract: A method is provided for producing a microfiber-reinforced high-strength concrete, comprising a cement matrix with a microfiber addition. The fiber elements have a shape-memory alloy. The method has at least the following steps: training a fiber shape of the fiber elements at a temperature above a transition temperature, wherein the fiber shape allows the fiber elements to latch; cooling the trained fiber elements; plastically deforming the fiber elements from the trained fiber shape into an intermediate form by means of which the fiber elements are prevented from latching; introducing the fiber elements into the cement matrix in order to form a fresh concrete; and casting the fresh concrete and heating the fresh concrete to the transition temperature such that the fiber elements reform into the fiber shape, thereby latching the fiber elements. The invention additionally relates to a microfiber-reinforced concrete which is produced using such a method.

  • Publication number: 20080012186
    Abstract: In a process for producing plastic components, a molded plastic article with a hollow space and relatively thick walls is molded in a first step, and, in an additional step, a predetermined fluid pressure is applied to the interior of the hollow space in the molded plastic article to enlarge it so that the thicknesses of the walls of the hollow space are reduced.
