Powder material impregnation method and method for producing fiber-reinforced composite material

A powder material impregnation method comprising:

• a first step of dispersing a powder of a predetermined material in a liquid to prepare a slurry;
• and
• a second step of burying a molded fabric body made of fiber bundles in the slurry and vibrating the slurry by use of a predetermined vibrator,
• wherein, in the second step, the slurry and the molded fabric body are fitted into a container having an inner shape corresponding to an outer shape of the molded fabric body, and the vibrator is arranged on a surface of the container to vibrate the slurry.
