Abstract

A semi-finished product arrangement for producing a fiber composite component by molding a planar semi-finished fiber composite product in a molding tool is provided. The arrangement includes the semi-finished fiber composite product and multiple holding elements fixed in place thereon and each extending beyond the edge of the semi-finished fiber composite product. The holding elements are countersunk in recesses of the semi-finished fiber composite product, in order to avoid a projection in terms of height.

First claim

The invention claimed is:

1. A semi-finished product arrangement for producing a fiber composite component by molding of a planar semi-finished fiber composite product in a molding tool, the arrangement comprising:
the planar semi-finished fiber composite product; and
multiple holding elements fixed in place on the planar semi-finished fiber composite product and each extending beyond a lateral edge of the planar semi-finished fiber composite product,
wherein the planar semi-finished composite product comprises multiple recesses,
wherein the multiple holding elements are countersunk in the recesses to avoid a height projection of the multiple holding elements,
wherein the holding elements are each elongated holding strips being attached to the planar semi-finished fiber composite product at a proximal end of the holding strip, and
wherein the proximal end is widened.

2. The semi-finished product arrangement of claim 1 , wherein the recesses each have a contour adapted to a contour of the corresponding holding element.

3. The semi-finished product arrangement of claim 1 , wherein the exposed surfaces of the holding elements are each arranged to be countersunk or at most substantially flush with a surface of the planar semi-finished fiber composite product in a region bordering on the recess.

4. The semi-finished product arrangement of claim 1 , wherein the holding elements are each disposed co-planar to a plane of the planar semi-finished fiber composite product.

5. The semi-finished product arrangement of claim 1 , wherein at least certain sections of the holding elements are formed entirely from a metal material.

6. The semi-finished product arrangement of claim 1 , wherein at least certain sections of the holding elements are formed entirely from a fiber-reinforced plastic material.

7. The semi-finished product arrangement of claim 1 , wherein the holding elements each possess a shaping providing a tension spring effect.

8. The semi-finished product arrangement of claim 1 , wherein the holding elements are each fixed in place on the planar semi-finished fiber composite product by rivets.
