<p>There is disclosed a highly shock-absorbing racket frame of fibre-reinforced plastics material has an outer shell 32 made from a plurality of fibre fabric sheets preimpregnated in epoxy resin and made up of fibres arranged in a predetermined orientation. The outer shell 32 located in the head portion 22, the shaft portion 26 and the grip portion 24 is provided with at least one shock-absorbing portion 36 fitted into a tubular bridging means 42 in such a manner that they are adhered securely. A first reinforced means 48 is used to cover the bordering portion of one end of bridging means 42 and outer shell in addition to the surface adjacent to bridging means and outer shell. A second reinforced means 50 is used to cover the bordering portion of another end of the bridging means 42 and the outer shell in addition to the surface adjacent to the bridging means and the outer shell. The shock wave generated in the head portion is therefore effectively absorbed and mitigated by the shock-absorbing portion. <IMAGE></p> |
