<p>A shock-absorbing racket frame made of fiber reinforced plastic material is mainly composed of a head frame and a shaft-handle portion. The racket frame is further provided with a thin plastic tube wrapped around by a first outer layer made of fiber reinforced plastic material and intended to form the head frame and the front segment of the shaft-handle portion. The thin plastic tube is furt her wrapped around by a second outer layer of fiber reinforced plastic material intended to form the hand grip of the shaft-handle portion.A reinforced surface of fiber reinforced plastic material is disposed across the gap between the two outer layers. The fibers making up the head frame are thus interrupted and disconnected with the fibers making up the hand grip of shaft-handle portion. Th e transmission of the shock wave from the head frame is therefore effectively interrupted at the position where the break of fibers takes place, thereby resul ting in the shock wave being mitigated to an extent that the player's hand holding th e racket is not subjected to injury.</p> |
