  • the invention relates to a tubular semi-finished fiber product, a fiber-reinforced plastic hollow profile, a method for producing a fiber semi-finished product and a method for producing a fiber-reinforced plastic hollow profile.
  • Fiber-reinforced plastic hollow profiles are known and are used, for example, as body components.
  • tubular fiber semi-finished products are used in which one or more layers of reinforcing fibers are arranged to form a preform that is similar to the later profile shape.
  • the semi-finished fiber product is then processed further to form a fiber-reinforced plastic component by infiltration with a plastic matrix, consolidation and / or curing of the same.
  • the cross section, the wall thickness and the material of the hollow profile result in a specific moment of bending resistance.
  • a tubular semi-finished fiber product is specified with at least one layer of reinforcing fibers, which is designed as a triaxial braid.
  • an additional, locally delimited fiber layer is arranged in at least one peripheral portion of the semi-finished product.
  • the semifinished fiber product - viewed along its circumference - has at least one partial area that is locally reinforced by an additional fiber layer.
  • the additional fiber layer extends in the circumferential direction preferably as far as the first partial area extends and over the entire length of the semifinished fiber product.
  • the semifinished fiber product thus has a strip-shaped local reinforcement. If the semi-finished fiber product is further processed into a fiber-reinforced plastic hollow profile by infiltration, consolidation and / or hardening of a matrix material, this component has increased stiffness and strength in the sub-area with a wall section that is thicker than the rest of the component. In this way, a component can be created in a particularly simple manner that shows different behavior in different loading directions.
  • the proposed semi-finished fiber product enables a load-appropriate construction of the component and the targeted use of material as required.
  • the semi-finished fiber product is tubular.
  • tubular is intended to describe an elongated hollow body, the length of which is many times greater than its height or width.
  • the cross-sectional shape of the tubular semi-finished fiber product is not limited to an annular shape. In addition to round cross-sections, oval or square, for example four-cornered or polygonal, cross-sections are also possible.
  • the semifinished fiber product has at least one layer of a triaxial braid.
  • the filaments of the braid are preferably aligned along the longitudinal axis of the semifinished fiber product, they preferably run in an angle range of + 1-5 degrees to the longitudinal axis of the semifinished fiber product.

  • the standing threads are fiber bundles (rovings) in which several or a large number of individual filaments are bundled.
  • standing threads made of the same material and of the same fineness are used throughout the braid.
  • the standing threads are carbon fibers, whereby a high level of rigidity and strength of the semi-finished fiber product or of the resulting fiber-reinforced component can be achieved.
  • the additional fiber layer can be at least one roving in the longitudinal direction of the semifinished fiber product.
  • the additional fiber layer can e.g. be designed as a fabric, braid or knitted fabric. A good reinforcement effect with particularly efficient use of material can be achieved in one embodiment in that the additional fiber layer is a unidirectional scrim in the longitudinal direction of the semi-finished fiber.
  • the additional fiber layer is preferably made up of carbon fibers, the use of other reinforcing fibers also being conceivable in principle.
  • the semifinished fiber product can have two or more layers of reinforcing fibers, preferably each as a triaxial braid, and two or more additional fiber layers that are alternately layered on top of each other. If several additional fiber layers are provided, then these are preferably formed in the same partial area so that they are aligned one above the other on the circumference.

  • the partial areas can have the same size and e.g. have the same number of rovings or be of different sizes, so that e.g. one sub-area has more rovings than another sub-area.
  • a fiber-reinforced plastic hollow profile which contains a fiber semifinished product according to the invention.
  • the semi-finished fiber product is then integrated into a plastic matrix.
  • the plastic matrix can be a thermoplastic plastic material or a thermosetting plastic material.

  • the additional fiber layer can thus be formed simply and without an additional process step.
  • More than one braid layer can be applied to the braided core, for example the mandrel can be passed several times through a braiding system so that a multi-layer braid is formed. If, as described above, an additional fiber layer is also formed, the result is a multi-layer structure in which each braid layer is underlaid by an additional fiber layer in the first partial area.
  • the procedure includes the steps:
  • the method is particularly preferably an RTM process (Resin Transfer Molding).
