Abstract

A building mold for producing shaped composite materials contains at least one first surface section, which is provided for shaping the composite material, and a second surface section, which is located substantially opposite the first section and is not provided for shaping the composite material. A heating device is arranged between the two sections. At least one planar metal structure, which is in thermal contact with the first surface section, is arranged between the first surface section and the second surface section or is on the first surface section and is configured to distribute the heat given off by the heating device in a planar manner.

First claim

The invention claimed is:

1. A building mold for manufacturing shaped composite materials, the building mold comprising:
at least one first surface section for shaping a composite material;
a second surface section lying generally opposite said first surface section and not provided for shaping the composite material;
a heating device disposed between said first and said second surface sections; and
at least one planar metal structure in thermal contact with said first surface section, said at least one planar metal structure at least regionally having notches, said planar metal structure one of disposed between said first surface section and said second surface section or on said first surface section, said planar metal structure distributing heat emitted by said heating device in a planar manner.

2. The building mold according to claim 1 , wherein said at least one planar metal structure has at least one of a metal mesh or a metal nonwoven.

3. The building mold according to claim 1 , wherein said at least one planar metal structure is disposed between said first surface section and said heating device.

4. The building mold according to claim 1 , wherein said at least one planar metal structure is laminated into the building mold.

5. The building mold according to claim 1 , wherein said at least one planar metal structure at least regionally has openings formed therein and distributed over a surface.

6. The building mold according to claim 1 , wherein said at least one planar metal structure has a surface weight of at least 500 g/m 2 and at most 2000 g/m 2 .

7. The building mold according to claim 1 , wherein:
said first surface section has a boundary surface; and
said at least one planar metal structure is spaced at most 25 mm apart from said boundary surface of said first surface section.

8. The building mold according to claim 1 , wherein said at least one planar metal structure is a randomly oriented nonwoven.

9. The building mold according to claim 1 , wherein said at least one planar metal structure at least partially has several layers of metal wires disposed one over the other.

10. The building mold according to claim 1 , wherein said at least one planar metal structure has a thermal conductivity of at least 17 W/(m·K).

11. The building mold according to claim 1 , wherein at least one of said first surface section or said second surface section is formed from at least one of a glass fiber-reinforced composite material or a carbon fiber-reinforced composite material.

12. The building mold according to claim 1 , wherein said first surface section, said second surface section, said heating device and said planar metal structure define a building mold half shell for manufacturing composite components of a rotor blade for wind power plants.

13. The building mold according to claim 1 , further comprising a molded part containing said planar metal structure and can be isolated from other parts of the building mold.

14. The building mold according to claim 13 , wherein said molded part is provided for molding reshaped composite parts.

15. The building mold according to claim 1 , wherein said at least one planar metal structure encompasses at least one of a copper mesh or a copper nonwoven.

16. The building mold according to claim 1 , wherein said at least one planar metal structure has a surface weight of 1700 g/m 2 .

17. The building mold according to claim 1 , wherein said at least one planar metal structure has a thermal conductivity of between 350 W/(m·K) and 400 W/(m·K).

18. The building mold according to claim 13 , wherein said molded part is provided for at least partially molding adhesive brackets of composite components in a rotor blade of wind power plants.

19. The building mold according to claim 1 , wherein said at least one planar metal structure is laminated over an entire surface.
