Problems solved by technology

Here, however, a low elongation at break has proven to be disadvantageous, especially in the case of hollow profiles made of carbon-fibre-reinforced plastic, which have a correspondingly low structural integrity

Embodiment Construction

[0029] exist figure 1 A reinforced fiber composite component 10 is shown in FIG. 2 , which in the illustrated embodiment is configured as a reinforcement component for an A-pillar of a vehicle by way of example. Of course, other hollow profiles, in particular structural body parts or other reinforcement components of a motor vehicle, can also be designed accordingly.

[0030] figure 2 shown in figure 1 Cross-section A-A of the reinforced fiber composite component 10 shown in . The fiber composite component comprises two interconnected fiber composite shells 11 , 12 which each comprise a cavity 13 , 14 . The two fiber composite shells 11 , 12 are connected to each other in such a way that their chambers 13 , 14 are arranged opposite each other and together define a cavity 15 . A metallic reinforcement profile 20 is arranged in this cavity 15 . The reinforcing profile 20 has a defined cross section which, in the embodiment shown, is configured as an irregular (asymmetrical...

Abstract

The invention relates to a fiber composite component and a method of manufacturing a reinforced fiber composite component. The method includes following steps of: providing a metal hollow body; subjecting the metal hollow body to plastic deformation to produce a metal reinforced section bar with a determined cross section; putting the produced metal reinforced section bar into a first cavity of a first fiber composite shell; and disposing at least one second fiber composite shell on the metal reinforced section bar so that a second cavity formed by the first cavity and the second fiber composite shell forms a hollow chamber for accommodating the metal reinforced section bar, wherein at least one of the steps includes connecting the metal reinforced section bar to at least one of the fiber composite shells in a material connection manner. The fiber composite component comprises the at least two fiber composite shells which are connected to each other. Each of the fiber composite shells comprises a cavity. The cavities determine the hollow chamber. The fiber composite component also comprises the metal reinforced section bar disposed in the hollow chamber and connected to at least one of the fiber composite shells in the material connection manner.

Description

technical field [0001] The invention relates to a method for producing a reinforced fiber composite component and a reinforced fiber composite component of shell construction. Background technique [0002] Fiber composite components are being used more and more in motor vehicles, since they are very rigid while being light in comparison to corresponding components made of purely metallic materials. [0003] Hollow beams are often used for this purpose, which are designed as generally longitudinally extending hollow profiles and provide a particularly favorable rigidity. For example, in this case it is a vehicle structural part or a reinforcing element with a supporting function. These hollow profiles can be assembled from a plurality of separately produced shell-like elements which are first produced individually and then glued together so that they together define a cavity. Here, however, a low elongation at break has proven to be disadvantageous, especially in the case o...
