Abstract
PURPOSE: To improve the moldability of groove on molded racket frame by composing core material of at least three-ply slices laminated in the hitting direction.
CONSTITUTION: A fiber reinforced plastic racket frame of manocoque structure provided peripherally, at least partially, with groove 31, is molded by hot pressing the frame molding material 20 consists of foamed synthetic resin core material 21 wrapped in the fiber reinforced plastic molding prepreg 22. Said core material 21 is composed of the three-ply slices 21a to 21c which are laminated in the hitting direction. The middle slice 21b located at the portion to be compressed, is formed so as to have it's thickness corresponding to the molded width of said groove. When molding the groove by compression of molding die 23, the middle slice is separately compressed having no effect an any other slices, so that overall deformation of the core material may be prevented.
