Abstract
A method of producing a badminton racket frame includes the following steps. Prepare a mold cavity. Wrap a number of layers of graphite fibers so as to form a shell shaped in the form of the racket frame. Insert solvent material into the shell. Arrange the shell within the mold cavity. Heat the solvent material to cause expansion and to generate pressure within the mold cavity so as to press against the layers of graphite fibers and thereby provide intimate bonding of the layers. Remove the shell as an integral composite badminton racket frame.
