Abstract
A prepreg for a sleeve member of fiber reinforced thermoplastic resin available for a tennis racket or a golf club is woven by using ribbon-shaped reinforcing fiber tows/uni-directional commingle yarns and matrix fiber tows, and the ribbon-shaped reinforcing fiber tows/commingle yarns make the prepreg and, accordingly, the sleeve product thin, light, highly dense, economical and large in mechanical strength.
