ABSTRACT:
A composite racket having at least one portion made of a thermoplastic resin and having the remaining portion made of a thermosetting resin is disclosed. The thermoplastic and thermosetting resins provide different dynamic stiffness, flexibility and toughness so that the racket possesses desired characteristics in the zones where they are necessary. The racket is fabricated by preforming a fiber reinforced thermoplastic resin in a first mold to form one of the frame portions and placing this preformed portion in a second mold. A fiber reinforced thermosetting resin is then formed into the other frame portion in the second mold and joined to the frame portion formed using thermoplastic resin at the throat section of the racket.
