Abstract

A method for forming a composite component, the method comprising: providing a first mould tool and a second mould tool, the first and second mould tools being configured so as to be capable of defining at least part of a mould cavity between them, and the second mould tool having a moulding surface defined by at least two demountable mould bodies; attaching the first mould tool to a press at a first workstation; subsequently, at a second workstation spaced from the first workstation, loading at least part of the second mould tool with reinforcement material whilst the first mould tool remains attached to the press at the first workstation; moving the second mould tool to the press at the first workstation in such a position as to confront the first mould tool; causing the press to effect relative movement of the first and second tools to bring the first and second tools into mating arrangement so as to define a mould cavity therebetween; and setting in shape the reinforcement material located in the mould cavity.

First claim

The invention claimed is:

1. A method for forming a composite component, the method comprising:
providing a first mould tool and a second mould tool, the first and second mould tools being configured so as to be capable of defining at least part of a mould cavity between them, and the second mould tool having a moulding surface defined by at least two demountable mould bodies;
attaching the first mould tool to a press at a first workstation;
subsequently, at a second workstation spaced from the first workstation, loading at least part of the second mould tool with first reinforcement material whilst the first mould tool remains attached to the press at the first workstation, wherein during the said loading step the demountable mould bodies of the second tool are demounted from each other by being brought out of mutual sealing engagement;
moving the second mould tool to the press at the first workstation in such a position as to confront the first mould tool, wherein the demountable bodies of the second mould tool are fixed in relative position to be in mutual sealing engagement during the moving of the second mould tool;
causing the press to effect relative movement of the first and second tools to bring the first and second tools into mating arrangement so as to define a mould cavity therebetween, the mould cavity having a surface that is defined at least in part by the moulding surface;
setting in shape the reinforcement material located in the mould cavity; and
after the said step of loading at least part of the second mould tool with the first reinforcement material at the second workstation, loading at least part of the second mould tool at the second workstation with further reinforcement material in such a way that the further reinforcement material overlaps at least part of the first reinforcement material.

2. A method as claimed in claim 1 , wherein the method comprises injecting a matrix material into the mould cavity and the step of setting in shape the reinforcement material comprises solidifying the matrix material.

3. A method as claimed in claim 2 , comprising injecting the matrix material into the mould cavity through the first mould tool.

4. A method as claimed in claim 1 , wherein the press effects relative movement of the first tool and at least one of the demountable mould bodies to bring them into mating arrangement.

5. A method as claimed in claim 1 , wherein the step of loading the second mould tool with reinforcement material comprises altering the shape of the reinforcement material relative to at least part of the second mould tool.

6. A method as claimed in claim 1 , comprising the steps, after the said setting step, of:
causing the press to effect relative movement of the first and second tools to bring the first and second tools out of mating arrangement;
removing the second mould tool from the press whilst the first mould tool remains attached to the press at the first workstation; and
removing from the second tool a shaped article formed of the reinforcement material.

7. A method as claimed in claim 1 , comprising the steps, after the said setting step, of:
causing the press to effect relative movement of the first and second tools to bring the first and second tools out of mating arrangement;
removing the second mould tool from the press whilst the first mould tool remains attached to the press at the first workstation;
separating the demountable tool bodies of the second mould tool; and
removing from the second tool a shaped article formed of the reinforcement material.

8. A method as claimed in claim 1 , comprising:
after the said step of loading at least part of the second mould tool, at the second workstation engaging with that part of the second mould tool, that part of the second mould tool being a first part of the second mould tool, a further part of the second mould tool, the further part of the second mould tool being configured so as to be capable of defining at least part of a mould cavity between itself, the first mould tool and the first part of the second mould tool;
and wherein the step of moving the second mould tool to the press comprises moving the first part of the second mould tool and the further part of the second mould tool together to the press.

9. A method as claimed in claim 1 , wherein the step of moving the second mould tool comprises moving the second mould tool on a path having a horizontal component.

10. A method as claimed in claim 1 , wherein the step of setting in shape the reinforcement material comprises heating the first mould tool.

11. A method as claimed in claim 1 , comprising heating the first mould tool when no other mould tool is confronting it in the press.

12. A method as claimed in claim 1 , wherein when the first and second mould tools define the mould cavity therebetween, they do so in cooperation with one or more further mould tools.

13. A method as claimed in claim 1 , wherein the mould cavity is a closed mould cavity.

14. A method as claimed in claim 1 , wherein the mould cavity is defined by moulding surfaces of the first and second mould tools.

15. A method as claimed in claim 1 , comprising connecting the first and further reinforcement materials to each other with a joining material in at least part of the overlapping area.

16. A method for forming a composite component, the method comprising:
providing a first mould tool and a second mould tool, the first and second mould tools being configured so as to be capable of defining at least part of a mould cavity between them, and the second mould tool having a moulding surface defined by at least two demountable mould bodies;
attaching the first mould tool to a press at a first workstation;
subsequently, at a second workstation spaced from the first workstation, loading at least part of the second mould tool with reinforcement material whilst the first mould tool remains attached to the press at the first workstation, wherein during the said loading step the demountable mould bodies of the second tool are demounted from each other by being brought out of mutual sealing engagement;
moving the second mould tool to the press at the first workstation in such a position as to confront the first mould tool, wherein the demountable bodies of the second mould tool are fixed in relative position to be in mutual sealing engagement during the moving of the second mould tool;
causing the press to effect relative movement of the first and second tools to bring the first and second tools into mating arrangement so as to define a mould cavity therebetween;
setting in shape the reinforcement material located in the mould cavity;
providing a third mould tool configured so as to be capable of defining at least part of a mould cavity between it and the first mould tool;
at a third workstation spaced from the first and second workstations, loading the third mould tool with reinforcement material whilst the first mould tool remains attached to the press at the first workstation and the second mould tool is located at the first workstation; and
whilst the second mould tool is absent from the first workstation:
(i) moving the third mould tool to the press at the first workstation in such a position as to confront the first mould tool;
(ii) causing the press to effect relative movement of the first and third mould tools to bring the first and third tools into mating arrangement so as to define a mould cavity therebetween;
(iii) injecting a matrix material into that mould cavity; and
(iv) solidifying the matrix material.
