Abstract: There is disclosed a method of manufacturing a composite component, the method comprising laying-up a plurality of successive plies of composite material to produce a pre-form (12) for the component in a lay-up procedure, wherein a portion of each ply of composite material is heated to at least a threshold temperature of 45° C. during a period of the lay-up procedure.

Abstract: A method of reinforcing a fiber reinforced resin matrix composite structure, the method including: providing a composite structure having one or more holes formed therein, and feeding a reinforcement rod through a passageway having one or more walls defining an inlet to the passageway. The inlet to the passageway is dimensioned to prevent a rod having a maximum cross sectional dimension greater than a predetermined dimension from passing through the passageway. In the event of the rod impacting the wall defining the inlet to the passageway, operation of the rig is stopped. In the event of the rod passing through the passageway without impacting the wall defining the inlet to the passageway, a portion of the rod is inserted into a hole in a composite structure.
