## Abstract

A device and method for manufacturing a bonded component with fiber-reinforced plastics having at least one base molding tool and at least one molding tool. The bonded component is arranged between the base molding tool and the molding tool. The bonded component has a base laminate and a reinforcement laminate. The molding tool is covered with an aeration material and a vacuum envelope. The vacuum envelope is sealed with respect to the base molding tool. At least one filler element is fitted to each of the two end faces of the base laminate in a gap-free manner. With the filler elements, as well as optionally provided sealing elements, undesirable cavities within the device, as a result of thermal expansion effects of the upper molding tool, as well as any deviations of location and/or size of the base laminate, the reinforcement laminate, and also the molding tool, are significantly reduced.

## Claims

### Claim at position 1

1-9. (canceled)

### Claim 10

A device for the manufacture of a bonded component with fiber-reinforced plastics comprising:
at least one base molding tool and at least one molding tool,
the bonded component being arranged between the base molding tool and the molding tool,
the bonded component having at least one base laminate and at least one reinforcement laminate,
the molding tool being covered with an aeration material and with a vacuum envelope,
the vacuum envelope being sealed with respect to the base molding tool, and
at least one filler element being fitted to each of the two end faces of the base laminate in an essentially gap-free manner.

### Claim 11 (depends on 10)

The device in accordance with claim 10, wherein at least one sealing element is inserted in each case between the filler elements and the end faces of the base laminate in an essentially gap-free manner.

### Claim 12 (depends on 10)

The device in accordance with claim 10, wherein the at least one molding tool exhibits high thermal expansion.

### Claim 13 (depends on 10)

The device in accordance with claim 10, wherein a material thickness of the at least one filler element and the at least one sealing element in each case approximately corresponds to a material thickness of the base laminate and the reinforcement laminate.

### Claim 14 (depends on 10)

The device in accordance with claim 10, wherein the filler elements are formed from at least one of a metallic material and a plastic material.

### Claim 15 (depends on 10)

The device in accordance with claim 10, wherein the at least one sealing element is formed from an elastic material.

### Claim 16 (depends on 15)

The device in accordance with claim 15, wherein the elastic material is a mixture of rubber and cork.

### Claim 17 (depends on 10)

The device in accordance with claim 10, wherein the filler elements and the sealing elements have in each case an approximately rectangular cross-sectional geometry.

### Claim 18 (depends on 10)

The device in accordance with claim 10, wherein the at least one molding tool with the two end sections rests on the filler elements, at least in some regions.

### Claim 19 (depends on 10)

A method for the manufacture of a bonded component with fiber-reinforced plastics using the device in accordance with claim 10.
