ABSTRACT:
A highly shock-absorbing racket frame of fiber reinforcing plastic material comprising an outer shell made from a plurality of fiber fabric sheets preimpregnated in epoxy resin and made up of fibers arranged in a predetermined orientation. The outer shell located in the head portion and the shaft portion is provided with at least one shock-absorbing portion fitted into a tubular bridging in a manner such that they are adhered securely. A first reinforcing is used to cover across a bordering portion of one end of the bridging and outer shell in addition to a surface adjacent to bridging and outer shell. A second reinforcing is used to cover across the bordering portion of another end of the bridging and outer shell in addition to the surface adjacent to the bridging and outer shell. The shock wave generated in the head portion is effectively absorbed and mitigated by the shock-absorbing portion.
