PURPOSE:To prepare continuously a rod-like fiber-reinforced resin material almost free from voids and if necessary, with high fiber content by preparing at first a sheet-like resin with a required fiber content and molding it into a rod-like shape. CONSTITUTION:A rod-like fiber-reinforced resin material wherein a reinforcing fiber is impregnated with a thermoplastic resin is prepd. In this case, the thermoplastic resin in a fiber-reinforced thermoplastic resin sheet 14 wherein a reinforcing fiber 7 arranged into a sheet-like shape is impregnated with a thermoplastic resin, is made into a softened condition by means of heating rollers 13. Thereafter, the reinforcing fiber impregnated with the thermoplastic resin is passed through a groove provided on a molding roll 30 by every specified number of filaments under tension. |
