Abstract
A method is provided for producing a fiber preform for a composite fiber component. In the method, at least one first fiber structure is braided in a braiding process over the entire length of the fiber preform to be produced and at least one second fiber structure is wound in a winding process over part of the length of the fiber preform to be produced.
Claims13
A method for producing a fiber preform for a fiber composite component, the method comprising the acts of:
- braiding, in a braiding process, at least a first fiber structure over an entire length of the fiber preform to be produced;
- and
- winding, in a winding process, at least a second fiber structure over a portion of the length of the fiber preform to be produced;
- wherein the winding process begins after the first fiber structure has already been braided over a predetermined length in the braiding process.
A fiber preform for a fiber composite component, comprising:
- a first braided fiber structure extending over an entire length of the fiber preform;
- and
- a second wound fiber structure extending over a portion of the entire length of the fiber preform, wherein the second wound fiber structure is arranged only in a locally limited region on the first braided fiber structure and beyond a predetermined length of the first braided fiber structure.
A fiber composite component, comprising:
- a fiber preform of the fiber composite component, the fiber preform comprising:
- a first braided fiber structure extending over an entire length of the fiber preform;
- and
- a second wound fiber structure extending over a portion of the entire length of the fiber preform, wherein
- the second wound fiber structure is arranged only in a locally limited region on the first braided fiber structure and beyond a predetermined length of the first braided fiber structure such that the fiber composite component has an increased transverse load absorption capacity in the region having the second wound fiber structure.
