Fibre placement tool
View Patent ↗A fiber placement tool comprising a plurality of tool segments, each tool segment having an outer surface defining a predetermined profile, each tool segment being removably mounted on at least one elongate shaft.
1. A method of manufacturing a fibre placement tool, comprising the steps of:
providing at least one elongate shaft;
providing a plurality of reusable tool segments each comprises a high density foam core and an outer layer of composite fibre;
forming an outer surface defining a predetermined profile on each of said plurality of reusable tool segments;
forming at least one through hole extending through each of said plurality of reusable tool segments along a longitudinal axis thereof;
passing said at least one elongate shaft through said at least one through hole; and,
removing and reusing any one of said plurality of reusable tool segments as needed.
2. The method of claim 1 , further comprising the step of forming a cross section of said at least one through hole to correspond to the cross section of the at least one elongate shaft.
3. The method of claim 1 , further comprising the step of providing a plurality of elongate shafts.
4. The method of claim 1 , further comprising the step of providing a means for securing the plurality of reusable tool segments on said at least one elongate shaft.
5. The method of claim 1 , further comprising the step of providing each tool segment with at least one reinforcing rib.
6. The method of claim 1 , further comprising the step of providing a longitudinal ridge on an outer surface of said at least one longitudinal shaft.
7. The method of claim 6 , further comprising the step of providing a longitudinal slot dimensioned and configured to receive said longitudinal ridge on each of said plurality of reusable tool segments.
8. A fibre placement tool, comprising:
at least one elongate shaft; and,
a plurality of reusable tool segments, each of said plurality of reusable tool segments comprises a high density foam core and an outer layer of composite fibre defining a predetermined profile and at least one through hole formed therein extending through each of said plurality of reusable tool segments along a longitudinal axis thereof through which said at least one elongate shaft passes, each of said plurality of reusable tool segments being removably mounted on the at least one elongate shaft.
9. A fibre placement tool according to claim 8 , wherein the at least one through hole has a cross section corresponding to the cross section of the at least one elongate shaft.
10. A fibre placement tool according to claim 8 , wherein the fibre placement tool comprises a plurality of elongate shafts.
11. A fibre placement tool according to claim 8 , wherein the cross section of the at least one of the elongate shaft is non-circular.
12. A fibre placement tool according to claim 8 , wherein the fibre placement tool includes means for securing the plurality of reusable tool segments on said at least one elongate shaft.
13. A fibre placement tool according to claim 8 , wherein each tool segment includes at least one reinforcing rib.
14. A fibre placement tool according to claim 8 , wherein said at least one longitudinal shaft includes a longitudinal ridge on an outer surface thereof.
15. A fibre placement tool according to claim 14 , wherein each of said plurality of reusable tool segments includes a longitudinal slot dimensioned and configured to receive said longitudinal ridge therewithin.
16. A fibre placement tool according to claim 12 , wherein said means for securing said plurality of reusable tool segments on said at least one elongate shaft is a circlip.
