A method of reinforcing a fibre reinforced resin matrix composite structure and a rig thereof comprises providing a composite structure having one or more holes formed therein; and inserting a reinforcement rod 38 into a hole provided in the composite structure using a rod insertion device 64. Rod is supplied to the rod insertion device from a rod supply system 62 that includes a reel 68 of rod material. Tension is removed from the reinforcement rod between the rod supply system and the rod insertion device preferably by feeding the rod from the supply system into an unsupported loop 72 and then into the rod insertion device. The rod insertion device may include a gripper (58, fig 5) for pulling rod from the supply system and directing a predetermined length into a hole of the composite structure. The rod supply system may comprise one or more tensioning systems and a tension monitoring system 80. The tension removal arrangement may include one or more sensors 76 to detect the amount of rod in the unsupported loop and a control system 82 for increasing the amount of rod in the loop when required. |
