Tool for curing a composite component
The present invention provides a tool 1 for curing a composite component, the tool comprising a lay-up surface 8 for laying-up layers of an uncured composite component, a cover assembly 9 for moving in relation to the lay-up surface to cover a layed-up uncured composite component on the lay-up surface, the cover assembly comprising a sealable cover for sealing around the uncured composite component on the lay-up surface to form a sealed zone, and a vacuum port 25 for providing a vacuum to the sealed zone, wherein the tool further comprises at least one heating element 15, 53 within the sealed zone for heating the uncured composite component. The invention also provides a method of manufacturing a composite component and a composite component. The composite component may form at least part of a piece of aircraft furniture, such as an aircraft seat shell.
1. A tool for curing a composite component, the tool comprising:
a lay-up surface for laying-up layers of an uncured composite component,
a cover assembly for moving in relation to the lay-up surface to cover a layed-up uncured composite component on the lay-up surface, the cover assembly comprising a sealable cover for sealing around the uncured composite component on the lay-up surface to form a sealed zone, and
a vacuum port for providing a vacuum to the sealed zone,
wherein the tool further comprises at least one heating element within the sealed zone for heating the uncured composite component and the sealable cover is pivotally mounted in relation to the lay-up surface.
2. The tool as claimed in claim 1 , wherein the cover assembly comprises a cover heating element for heating an upper side of the layed-up uncured composite component.
3. The tool as claimed in claim 2 , wherein the cover heating element comprises a heating blanket formed of a wire mesh, embedded within a carrier material.
4. The tool as claimed in claim 1 , wherein the sealable cover is a three-dimensionally shaped cover that holds its shape such that the sealable cover has a volume associated with it for containing the uncured composite component.
5. The tool as claimed in claim 4 , wherein the sealable cover is shaped such that the sealable cover has a lower edge region that can seal around the lay-up surface and a roof region that holds a shape of the roof region to extend above the lay-up surface.
6. The tool as claimed in claim 1 , wherein the sealable cover is supported by a frame structure.
7. The tool as claimed in claim 1 , wherein the tool further comprises a cooling apparatus for cooling the composite component.
8. The tool as claimed in claim 7 , wherein the cooling apparatus comprises a vortex tube for supplying cooling air.
9. The tool as claimed in claim 1 , wherein the at least one heating element is embedded beneath a top layer of the lay-up surface.
10. A tool for curing a composite component, the tool comprising a main body and a lay-up surface portion for laying-up layers of an uncured composite component, wherein the lay-up surface portion is removable from the main body of the tool, and wherein the removable lay-up surface portion comprises a removable electrical connector and the main body comprises an electrical connection point corresponding to the removable electrical connector of the removable lay-up surface portion and
wherein the removable electrical connector is configured such that it can be interchangeably connected and disconnected from the electrical connection point.
11. The tool as claimed in claim 10 , wherein the removable lay-up surface portion comprises a vacuum port connector and the main body comprises a corresponding vacuum port.
12. The tool as claimed in claim 10 , wherein the removable electrical connector comprises a plug, and the electrical connection point comprises a socket.
