Abstract
A semi-finished product for the manufacture of a structural component has a plurality of prepreg tapes, each having unidirectionally arranged reinforcing fibers embedded in a thermoplastic matrix material, and with a plurality of connecting strands containing a thermoplastic material. The prepreg tapes and the connecting strands are either joined to form a textile sheet structure or the prepreg tapes are arranged to form a multiaxial fabric, individual layers of the fabric being joined by the connecting strands. Further, a method for manufacturing a curved structural component from such a semi-finished product is described.

A semi-finished product for manufacturing of a structural component, comprising:
- a plurality of prepreg tapes extending along each other, each having unidirectionally arranged reinforcing fibers embedded in a thermoplastic matrix material;
- and
- a plurality of connecting strands comprising a thermoplastic material;
- wherein the connecting strands and the prepreg tapes are connected to form a single-layer textile sheet structure in which each of the connecting strands crosses a plurality of the prepreg tapes;
- and
- wherein the connecting strands and the prepreg tapes are joined to one another along respective connecting lines by way of a material joint in a first end region of the sheet structure and in a second end region of the sheet structure positioned opposite to the first end region.
A semi-finished product for manufacturing of a structural component, comprising:
- a plurality of prepreg tapes each having unidirectionally arranged reinforcing fibers embedded in a thermoplastic matrix material;
- wherein the prepreg tapes are arranged in a multiaxial fabric comprising several superimposed layers of prepreg tapes;
- wherein the prepreg tapes run parallel to each other within a layer;
- wherein the layers are joined relative to each other on single positions, by a plurality of connecting strands containing a thermoplastic material, and
- wherein the connecting strands are formed as foil tapes having the thermoplastic material.
