Racket frame and process for producing the same

Abstract

A racket frame, which has a frame main body 12 made of a fiber reinforced plastic, an ionomer film 13 covering the frame main body 12, and a coating film 15 formed over the ionomer film 13, is provided with a gas permeable porous material film 14 interposed between the ionomer film 13 and the coating film 15 so as to reduce voids inside the frame main body 12 and between the frame main body 12 and the ionomer film 13. Since voids are reduced inside the frame main body 12 and between the frame main body 12 and the ionomer film 13, and since the ionomer film 13 is reinforced with the gas permeable porous material film 14, the racket frame has an excellent mechanical strength. Adhesion between the frame main body 12 and the ionomer film 13 is excellent. Adhesion between the gas permeable porous material film 14 and the coating film 15 is good.
