摘要： Disclosed herein a method for making a unidirectional continuous fiber-reinforced resin composite material. A resin plasticized and molten by an extruder is transported to a coating guide roller through a die head, and a hot-melt resin film layer with uniform thickness is formed on a roller surface of the coating guide roller. Simultaneously, the coating guide roller guides the hot-melt resin to continuously and uniformly coat on a row of flattened unidirectional continuous fibers along the roller surface of the coating guide roller. Subsequently, the coated flattened unidirectional continuous fibers pass through an open dip-coating roller device to effectively combine with the hot-melt resin to obtain a composite material of the hot-melt resin and fibers, which passes through a cooling and forming device to a winder under a driving force of a main traction to obtain the unidirectional continuous fiber-reinforced resin composite material.
