Abstract

The method includes a step of holding a surface of a filter part (22A), 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 (12A) including a carbon fiber bundle as weaving yarn, a step of immersing the woven fabric (12A) on which the filter part (22A) 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 (12A) on which the filter part (22A) is held from the dispersion and removing the filter part (22A) from the woven fabric (12A).

First claim

The invention claimed is:

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.
