A repair process for a damaged fibre-reinforced structure, such as the frame of a sports racquet, comprises the steps of making a window in the structure across the damaged area and filling the exposed cavity at the damaged area with a combination of reinforced fibres wetted out with a curable resin, and a plug. The plug is preferably a short length of solid rod, for instance of fibre-glass and polyester material, and is packed to either side in the structure with the reinforcing fibres which may be provided by Kevlar rovings. The repair is further reinforced by a curable overlay.
