Abstract

A semi-finished textile for producing a fiber composite component part has a textile structure and a fixation structure so as to provide a semi-finished textile that can be easily handled and that is suitable for use in complex component part shapes. The textile structure includes a first multitude of reinforcement-fiber bundles of high-performance fibers. Displacement sections are formed between adjacent reinforcement-fiber bundles and adjacent reinforcement-fiber bundles can be displaced against each other. The fixation structure fixates the reinforcement-fiber bundles, depending on the textile structure, with a fixation pattern in such a way that the reinforcement-fiber bundles are fixated at least partially and the displacement sections remain at least partially free.

First claim

What is claimed is:

1. A method for manufacturing a semi-finished textile for producing a fiber composite component part, the method comprising:
assembling a textile structure from a first multitude of reinforcement-fiber bundles, wherein bundles displacement sections are formed between adjacent reinforcement-fiber bundles that are displaceable against each other;
placing a fixation structure onto the textile structure;
fixating the reinforcement-fiber bundles by means of the fixation structure by applying a fixation pattern so that the reinforcement-fiber bundles are at least partially fixated and the displacement sections remain at least partially free,
wherein the fixation pattern includes predetermined fixation points on each of the reinforcement-fiber bundles,
wherein the predetermined fixation points on each of the reinforcement-fiber bundles is a central zone of each of the reinforcement-fiber bundles,
wherein the fixation structure includes a multitude of meltable binder yarns fixated to each of the reinforcement-fiber bundles only in the central zone of each of the reinforcement-fiber bundles, and
wherein each meltable binder yarn of the multitude of meltable binder yarns includes a binding material.

2. The method as recited in claim 1 , wherein the reinforcement-fiber bundles are connected with each other, and wherein the fixation structure has a binder that at least partially fixates the reinforcement-fiber bundles.

3. The method as recited in claim 1 , wherein the fixation structure has a connection structure connecting the reinforcement-fiber bundles with each other, wherein the connection structure includes a second multitude of connection elements having a binder, and wherein the connection elements are connected with the reinforcement-fiber bundles by melting of the binder.

4. The method as recited in claim 1 , wherein the fixation pattern is a line pattern or a dot pattern that is formed in relation to the textile structure.

5. The method as recited in claim 1 , wherein the fixation pattern extends over an entire surface of the semi-finished textile.

6. The method as recited in claim 1 , wherein the fibers of the reinforcement-fiber bundles are carbon fibers or glass fibers.

7. The method as recited in claim 1 , wherein the first multitude of reinforcement-fiber bundles of fiber have a flat surface carrying the predetermined fixation points.

8. The method as recited in claim 1 , wherein each meltable binder yarn of the multitude of meltable binder yarns includes the binding material extending over an entire length of each meltable binder yarn.

9. The method as recited in claim 1 , wherein each meltable binder yarn of the multitude of meltable binder yarns includes the binding material only at positions on each meltable binder yarn overlaying the predetermined fixation points on each of the reinforcement-fiber bundles.
