PROBLEM TO BE SOLVED: To provide a method for producing a fiber-reinforced composite material which can enhance the impregnation of a resin into a fiber bundle, enable the use of a high-molecular-weight resin, and greatly improve the take-up speed. SOLUTION: A fiber bundle has a liquid substance (for example, liquid paraffin) having a boiling point higher than the temperature of a molten resin in a die in advance. After the contact treatment, a fiber-reinforced composite material is produced by introducing the mixture into a die and bringing it into contact with a molten thermoplastic resin, withdrawing from the die, and cooling. |
