Abstract

A vehicle body includes a first body component made of fiber-reinforced plastic and a second body component made of fiber-reinforced plastic. The body components are adhesively bonded to each other by an adhesive layer and are subjected to shearing load and/or tensile stress in a main stress plane, wherein the adhesive layer is shaped by way of an adhesive flange, on which the adhesive layer is oriented obliquely to the main loading plane at an angle between 30° and 60°.

First claim

What is claimed is:

1. A vehicle body, comprising:
a first body component of fiber-reinforced plastic;
a second body component of fiber-reinforced plastic;
an adhesive layer bonding the first and second body components to one another; and
a third body component, wherein
the first and second body components are subjected to shear stress and/or tensile stress in a main stress plane,
the adhesive layer is shaped via an adhesive flange, on which adhesive flange the adhesive layer is oriented obliquely relative to the main stress plane at an angle of between 30° and 60°, and
an adhesive layer of the third body component in relation to the first or second body components is arranged to superimpose on the adhesive layer between the first and second body components.

2. The vehicle body according to claim 1 , wherein the adhesive layer is oriented obliquely relative to the main stress plane at an angle of between 40° and 50°.

3. The vehicle body according to claim 1 , wherein the adhesive layer is oriented obliquely relative to the main stress plane at an angle of approximately 45°.

4. The vehicle body according to claim 1 , wherein the first and second body components form an A-pillar of a passenger cabin.

5. The vehicle body according to claim 1 , wherein
the first body component forms a side frame of a passenger cabin, and
the second body component forms an annular frame lower part of the passenger cabin.

6. The vehicle body according to claim 1 , wherein the third body component is formed of fiber-reinforced plastic.

7. The vehicle body according to claim 1 , wherein
the first and second body components form a side frame of a passenger cabin, and
the third body component forms a bulkhead of the passenger cabin.

8. The vehicle body according to claim 6 , wherein
the first and second body components form a side frame of a passenger cabin, and
the third body component forms a bulkhead of the passenger cabin.

9. A vehicle body, comprising:
a first body component of fiber-reinforced plastic;
a second body component of fiber-reinforced plastic;
an adhesive layer bonding the first and second body components to one another; and
another adhesive layer adhesively bonding the first and second body components to one another, wherein
the first and second body components are subjected to shear stress and/or tensile stress in a main stress plane,
the adhesive layer is shaped via an adhesive flange, on which adhesive flange the adhesive layer is oriented obliquely relative to the main stress plane at an angle of between 30° and 60°, and
the another adhesive layer is shaped by a curved adhesive flange.

10. A vehicle body, comprising:
a first body component formed of fiber-reinforced plastic;
a second body component formed of fiber-reinforced plastic;
an adhesive layer configured to adhesively bond the first and second body components to one another, the first and second body components being subjected to shear stress and/or tensile stress in a main stress plane; and
a third body component, wherein
the adhesive layer is shaped by a curved adhesive flange, and
the third body component is adhesively bonded to at least one of the first and second body components via a further adhesive layer,
the further adhesive layer being shaped by an adhesive flange, on which adhesive flange the further adhesive layer is oriented obliquely relative to the main stress plane at an angle between 30° and 60°.

11. The vehicle body according to claim 9 , wherein
the first body component forms a sill reinforcement of a passenger cabin, and
the second body component forms a side frame of the passenger cabin.

12. A vehicle body, comprising:
a first body component of fiber-reinforced plastic;
a second body component of fiber-reinforced plastic; and
an adhesive layer bonding the first and second body components to one another, wherein
the first and second body components are subjected to shear stress and/or tensile stress in a main stress plane,
the adhesive layer is shaped via an adhesive flange, on which adhesive flange the adhesive layer is oriented obliquely relative to the main stress plane at an angle of between 30° and 60°, and
the adhesive layer has a thickness of 1.4 mm to 1.6 mm.

13. A vehicle body, comprising:
a first body component formed of fiber-reinforced plastic;
a second body component formed of fiber-reinforced plastic; and
an adhesive layer configured to adhesively bond the first and second body components to one another, the first and second body components being subjected to shear stress and/or tensile stress in a main stress plane, wherein
the adhesive layer is shaped by a curved adhesive flange, and
the adhesive layer has a thickness of 1.4 mm to 1.6 mm.
