ABSTRACT:
A sports racket frame comprises an outer shell made of a fiber-reinforced composite. Located at a predetermined area of the outer shell encasing the handle portion are slits in the shell and a plurality of strength-reinforcing and shock-absorbing inlay pieces which reduce effectively the shock wave originating from the ball-hitting surface to a minimum and to give the racket frame an added elasticity and rigidity.
