摘要： Provided herein is a molding material that attains little fluctuation in amount of short fibers and powdery resin among individual products and that allows continuous production without damaging a die. In the step of pouring, slurry is poured onto a slurry diffusion member 7 from above the slurry diffusion member 7. The slurry diffusion member 7 extends in an upward direction, and is shaped such that the area of a transverse section taken along a direction orthogonal to the upward direction becomes smaller as the slurry diffusion member 7 extends in the upward direction. In the step of cleaning, a dispersion medium that is the same as the dispersion medium used in the step of pouring or water is poured onto the slurry diffusion member 7 from above the slurry diffusion member 7 to cause the short fibers and the powdery resin adhering to a slurry diffusion portion 71 of the slurry diffusion member 7 to fall down. After that, the dispersion medium is discharged from a cylindrical die 3 to accumulate the short fibers and the powdery resin in the cylindrical die 3 to obtain an aggregate 38 of the short fibers and the powdery resin. Then, the aggregate 38 is compressed.

摘要： There is little fluctuation in amount of short fibers among individual products of fiber substrate. No damage is caused to a mold for the fiber substrate. Continuous production of the fiber substrates is possible. A method of manufacturing a fiber substrate includes the steps of: preparing slurry by dispersing short fibers in a dispersion medium; pouring the slurry into a cylindrical mold from above the cylindrical mold, the slurry being directed to a slurry diffusion member disposed in the center of the cylindrical mold and having an upward pointing conical or pyramidal shape; pouring the dispersion medium or water onto the slurry diffusion member from above the slurry diffusion member to cause the short fibers adhering to the slurry diffusion member to fall down, after the step of pouring the slurry; and discharging the dispersion medium from the cylindrical mold to accumulate the short fibers in the cylindrical mold to obtain a fiber aggregate.
