Abstract

The bridge (3) between the arms (2) of the grip (1) is also a tube of consolidated thermoplastic fibre/carbon fibre-hybrid yarn, which is filled with a foamed thermoplastic with a density between 20 and 400 g/l. The thermoplastic fibres comprise a polyamide and the plastic foam is a polyamide, a polysulphone or a polyether sulphone. To make the racquet frame, a tubular network of thermoplastic/carbon fibre/hybrid yarn is formed, into which is introduced a flexible, thin-walled, inflatable hose. The tubular network is formed into the shape of a racquet frame, and a piece of tubular hybrid yarn network is laid as bridge (3) between the arms (2) of the frame so that the two arms are encompassed by two tongue-shaped segments of the bridge. The frame is placed in a metal mould which is then closed. The hose is then inflated exerting a pressure on the hybrid yarn network which by subsequent heating is consolidated to form a fibre-reinforced tube.
