Abstract

A method for producing a lower part of a rear spoiler of a motor vehicle includes providing at least one insert part and fibers, arranging the fibers and the at least one insert part in a mold, and incorporating a matrix into the mold. The method further includes molding the lower part of the rear spoiler in the mold, wherein the insert parts are laminated into the structure of the lower part, and milling the insert part after the molding of the lower part.

First claim

What is claimed is:

1. A method for producing a lower part of a rear spoiler of a motor vehicle, the method comprising:
providing at least one insert part and fibers;
arranging the fibers and the at least one insert part in a mold;
incorporating a matrix into the mold;
molding the lower part of the rear spoiler in the mold, wherein the at least one insert part is laminated into the structure of the lower part such that the fibers and the molded matrix surround at least an entire lateral periphery of the insert part; and
milling the at least one insert part after the molding of the lower part, the at least one insert part having an opening configured to guide and accept a fastener for attaching the lower part of the rear spoiler to the motor vehicle.

2. The method as claimed in claim 1 , wherein a depression is incorporated into the at least one insert part by the milling.

3. The method as claimed in claim 2 , wherein a depression that in the cross section is circular is incorporated into the at least one insert part by the milling.

4. The method as claimed in claim 1 , wherein the milling is performed in such a manner that the spacing between a surface of the at least one insert part, obtained by the milling, and a lower side of the lower part corresponds to a predefined spacing.

5. The method as claimed in claim 3 , wherein a surface in a base of the depression is obtained by the milling.

6. The method as claimed in claim 1 , wherein the at least one insert part is produced from a metallic material.

7. A lower part of a rear spoiler of a motor vehicle, wherein the lower part is produced by a method as claimed in claim 1 .

8. A motor vehicle comprising at least one body component and a rear spoiler having a lower part as claimed in claim 7 , wherein the lower part is fastened to the body component by the fastener, which passes through the opening.

9. The method as claimed in claim 6 , wherein the metallic material is aluminum.

10. The method as claimed in claim 1 , wherein the arranging of the fibers and the at least one insert part in the mold comprises arranging a plurality of insert parts spaced apart from each other,
wherein during the molding of the lower part of the rear spoiler in the mold, the plurality of inserts parts are laminated into the structure of the lower part, and
wherein the milling of the at least one insert part after the molding of the lower part comprises milling the plurality of insert parts, each of the insert parts having their respective opening configured to guide and accept the respective fastener for attaching the lower part of the rear spoiler to the motor vehicle.
