Abstract

Provided are a method for manufacturing a composite fabric capable of further improving the strength of a carbon fiber-reinforced molded article, a composite fabric, and a carbon fiber-reinforced molded article. The method includes a step of holding a surface of a filter part ( 22 A), through which a dispersion solvent and carbon nanotubes dispersed in the dispersion solvent are allowed to pass, in contact with at least one surface of a woven fabric ( 12 A) including a carbon fiber bundle as weaving yarn, a step of immersing the woven fabric ( 12 A) on which the filter part ( 22 A) is held in a dispersion that comprises the dispersion solvent and the dispersed carbon nanotubes and applying ultrasonic vibrations to the dispersion, and a step of extracting the woven fabric ( 12 A) on which the filter part ( 22 A) is held from the dispersion and removing the filter part ( 22 A) from the woven fabric ( 12 A).

Claims (7)

1. A method for manufacturing a composite fabric, the method comprising:

holding a surface of a filter part, through which a dispersion solvent and carbon nanotubes dispersed in the dispersion solvent are allowed to pass, in contact with at least one surface of a woven fabric comprising carbon fiber bundles as weaving yarn;

immersing the woven fabric on which the filter part is held in a dispersion that comprises the dispersion solvent and the carbon nanotubes dispersed in the dispersion solvent and applying ultrasonic vibrations to the dispersion; and

extracting the woven fabric on which the filter part is held from the dispersion and removing the filter part from the woven fabric.

2. The method for manufacturing a composite fabric according to claim 1 , wherein the filter part is provided on both sides of the woven fabric and held pressed against the woven fabric.

3. The method for manufacturing a composite fabric according to claim 2 , wherein the filter part is held pressed against the woven fabric by a holding part whose surface protrudes curvedly in a thickness direction.

4. The method for manufacturing a composite fabric according to claim 1 , wherein the filter part is held in a state where the woven fabric is wound in a roll shape such that the filter part faces an outside.
