Abstract

The present invention provides an apparatus and a method for applying resin to a plurality of fibres, comprising: a housing (10) having at least one fibre entry port (20) and at least one fibre exit port; at least one fibre spreading surface (50a) arranged, in use, to spread a plurality of fibres as they move over the at least one fibre spreading surface; and at least one resin applicator head located within the housing, the at least one resin applicator head being arranged, in use, to apply resin to the fibres as they move past the at least one resin applicator head.

Claims

1. An apparatus for applying resin to a plurality of fibres, comprising:

a housing having at least one fibre entry port and at least one fibre exit port;

at least one fibre spreading surface arranged, in use, to spread a plurality of fibres as they move over the at least one fibre spreading surface; and

at least one resin applicator head located within the housing, the at least one resin applicator head being arranged, in use, to apply resin to the fibres as they move past the at least one resin applicator head.

2. The apparatus as claimed in claim 1, wherein the at least one fibre spreading surface is located within the housing.

3. The apparatus as claimed in claim 1, wherein the at least one fibre spreading surface is profiled.

4. The apparatus as claimed in claim 3, wherein the at least one fibre spreading surface is concave or convex.

5. The apparatus as claimed in claim 1, wherein the at least one fibre spreading surface is a surface of a fibre spreading pin.

6. The apparatus as claimed in claim 2, wherein the at least one fibre spreading surface is a surface of the at least one resin applicator head.

7. The apparatus as claimed in claim 1, further comprising at least one fibre gathering surface arranged, in use, to gather the plurality of fibres as they move over the at least one fibre gathering surface.

8. The apparatus as claimed in claim 7, wherein the at least one fibre gathering surface is a surface of a fibre gathering pin.

9. The apparatus as claimed in claim 1, wherein the at least one fibre spreading surface, and/or the at least one resin applicator head, is an interchangeable modular component.

10. The apparatus as claimed in claim 7, wherein the at least one fibre gathering surface is an interchangeable modular component.

11. The apparatus as claimed in claim 1, wherein the at least one resin applicator head comprises a resin applicator slot.

12. The apparatus as claimed in claim 1, further comprising at least one resin collector located proximate the at least one fibre exit port.

13. The apparatus as claimed in claim 1, further comprising a resin mixer arranged, in use, to supply resin to the at least one resin applicator head on demand, wherein the resin mixer is arranged to mix at least two resin precursor materials together to form the resin.

14. The apparatus as claimed in claim 1, further comprising at least one sensor, wherein the at least one sensor is arranged to sense a parameter of the resin and/or a parameter of the fibres.

15. The apparatus as claimed in claim 1, further comprising a resin heater.

16. The apparatus as claimed in claim 1, further comprising a curing apparatus located proximate the at least one fibre exit port.

17. A method of applying resin to a plurality of fibres, comprising:

passing a plurality of fibres through a housing containing at least one resin applicator head;

spreading the plurality of fibres over at least one fibre spreading surface; and

applying resin to the fibres as they move past the at least one resin applicator head.

18. The method as claimed in claim 17, wherein the at least one fibre spreading surface is located within the housing.

19. The method as claimed in claim 17, further comprising curing the resin substantially as the fibres exit the housing.

20. A kit of parts for forming a resin applicator, comprising:

a housing having at least one fibre entry port and at least one fibre exit port;

at least one fibre spreading surface; and

at least one resin applicator head,

wherein the at least one resin applicator head is arranged to be located within the housing.

21. The kit of parts as claimed in claim 20, wherein the at least one fibre spreading surface is a surface of the at least one resin applicator head.

22. The kit of parts as claimed in claim 20, wherein the at least one fibre spreading surface is a surface of a fibre spreading pin.

23. The kit of parts as claimed in claim 20, further comprising at least one fibre gathering surface.

24. The kit of parts as claimed in claim 23, wherein the at least one fibre gathering surface is a surface of a fibre gathering pin.

25. The kit of parts as claimed in claim 20, wherein the at least one fibre spreading surface and/or the at least one resin applicator head is an interchangeable modular component.

26. The kit of parts as claimed in claim 23, wherein the at least one fibre gathering surface is an interchangeable modular component.
