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.
Claims9
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.
