  • Patent number: 10507623
    Abstract: A pressing tool is provided for producing fiber composite components, including a first tool part and a second tool part moveable relative to the first tool part. In the closed state of the pressing tool, the two tool parts form a shaping cavity for accommodating a fiber semi-finished product to be shaped and each have a tool surface delimiting the cavity. In addition, at least one of the tool surfaces has at least two adjacent flat sections inclined toward each other which are connected to each other by way of a curved transition section. The curved transition section has at least one groove-shaped recess facing the cavity.
    Type: Grant

  • Publication number: 20140193625
    Abstract: A process for the production of a component (1) made of a fiber composite material, and also a component (1) produced in this way, are stated, where a foil composite (7) with a thermoplastic outer foil (6) and with a thermoplastic inner foil (5) is produced, where the modulus of elasticity (E) of the inner foil (5) within a temperature range is smaller than the modulus of elasticity (E) of the outer foil (6), the inner foil (5) of the foil composite (7) is bonded to a molding (4) comprising a fiber material (2) and comprising a thermoset (3), the molding (4) is hardened, and the foil composite (7) is subjected to a heat treatment in the temperature range within which the modulus of elasticity (E) of the inner foil (5) is smaller than the modulus of elasticity (E) of the outer foil (6), where the outer foil (6) undergoes stress relaxation.
