Abstract

A vehicle structural component includes at least one first and at least one second fiber-reinforced plastics insert, an injection-molded rib structure, where the injection-molded rib structure connects the plastic inserts and is injection-molded onto the plastic inserts, and at least one metal element which forms an attachment region of the vehicle structural component.

First claim

What is claimed is:

1. A vehicle structural component, comprising:
a first pair of fiber-reinforced plastics inserts;
a second pair of fiber-reinforced plastics inserts;
wherein the first pair of fiber-reinforced plastics inserts and the second pair of fiber-reinforced plastics inserts run along a longitudinal direction of the vehicle structural component, wherein the first pair of fiber-reinforced plastics inserts runs along an upper side of the vehicle structural component, and wherein the second pair of fiber-reinforced plastics inserts runs along a lower side of the vehicle structural component;
an injection-molded rib structure, wherein the first pair of fiber-reinforced plastics inserts and the second pair of fiber-reinforced plastics inserts are partially surrounded by the injected-molded rib structure and are embedded in the injected-molded rib structure; and
a metallic element connected to the injection-molded rib structure which forms an attachment region of the vehicle structural component;
wherein at least one of the fiber-reinforced plastics inserts of the first and the second pairs of fiber-reinforced plastics inserts protrudes through a recess in the metallic element.

2. The vehicle structural component according to claim 1 , wherein the metallic element is connected to the injection-molded rib structure by one of an integrally bonded connection, a frictional connection, or a form-fitting connection.

3. The vehicle structural component according to claim 1 , wherein the injection-molded rib structure has a plurality of reinforcing webs running at an angle in relation to the first and the second pairs of fiber-reinforced plastics inserts and with respect to one another as seen in a cross section.

4. The vehicle structural component according to claim 1 , wherein, as seen in a cross section, at least two adjacent reinforcing webs form a local reinforcing unit with one of the first and the second pairs of fiber-reinforced plastics inserts.

5. The vehicle structural component according to claim 1 , wherein, in the longitudinal direction of the vehicle structural component, a plurality of reinforcing webs run consecutively transversely with respect to the longitudinal direction.

6. The vehicle structural component according to claim 1 , wherein, in the longitudinal direction of the vehicle structural component, a plurality of reinforcing webs run consecutively transversely with respect to the longitudinal direction and wherein the plurality of reinforcing webs are disposed spaced apart from one another in the longitudinal direction.

7. The vehicle structural component according to claim 1 , wherein the injection-molded rib structure is a short-fiber-reinforced thermoplastic and/or the first and the second pairs of fiber-reinforced plastics inserts include an endless fiber material.
