  • Publication number: 20240140062
    Abstract: The invention relates to a pressing system, including a press having a first pressing tool and a second pressing tool. The first pressing tool and the second pressing tool being movable relative to one another to form a working space. A workpiece, a pressure generating device for generating a pressure curve acting on the workpiece in the working space, a temperature generating device for generating a temperature curve acting on the workpiece in the working space the workpiece running through an elongation curve (DVW) depending on the pressure curve acting in the working space and on the temperature curve acting in the working space. The first pressing tool and the second pressing tool running through a respective elongation curve (DVP1, DVP2) depending on the pressure curve acting in the working space and on the temperature curve acting in the working space, wherein the first pressing tool and/or the second pressing tool are designed such that their elongation curve (DVP1, DVP2) deviates by no more than 3.

  • Publication number: 20220410503
    Abstract: A method and a device for producing a component from a fiber composite material. The method includes introducing multiple layers of fibers impregnated with a matrix onto an inner mold, placing a membrane sealed against an outer mold onto the fibers impregnated with the matrix, such that a cavity extending along the shell surface of the outer mold forms between the outer mold and the membrane, and applying a temperature-controllable pressure fluid to the cavity at a temperature greater than the melting point of the matrix and at a pressure greater than the ambient pressure. To produce a component having at least one reinforcing layer, at least one reinforcing layer having fibers oriented in a predominantly parallel manner is placed locally onto a portion of a side of a the base layer facing the outer mold with the aid of an insertion device and a membrane with an average surface roughness of below 1.0 ?m, preferably below 0.1 ?m, subsequently exerts a set pressure in the cavity on the component.

  • Publication number: 20220281185
    Abstract: A method is specified for producing a structural component, in particular for an aircraft, ground vehicle, or watercraft, or for a rotor blade of a wind turbine, in which method an arrangement of fibers and plastic material is laid in a mold and subjected to an increased pressure and an increased temperature, wherein a mold is used which comprises at least one recess in which a reinforcing element is arranged. The object is to be able to cost-effectively produce a structural component of this type. For this purpose, it is provided that the reinforcing element is laid in the recess together with a core, wherein a differential volume between the recess and core, at least in a predetermined region, is chosen such that it is smaller than a segment of the reinforcing element arranged in said region by a predetermined amount.

  • Publication number: 20220274293
    Abstract: A method for producing a component from a fiber-composite material includes introducing a fiber impregnated with a matrix onto the inner mold of a mold space formed between the inner mold and an outer mold, introducing a separating membrane onto the fiber impregnated with the matrix such that a cavity extending along the lateral surface of the outer mold is formed between the outer mold and the separating membrane, supplying a thermal oil to the cavity at a pressure that is greater than ambient pressure such that the thermal oil acts on the separating membrane at the pressure, heating the thermal oil to above a glass transition temperature of the matrix, and cooling the thermal to below the glass transition temperature of the matrix, wherein the pressure of the thermal oil on the separating membrane is kept substantially constant at least during the cooling to below the glass transition temperature.
