Japanese Patent JP7398235
Kind Code:
B2
Abstract:
To provide a method for producing a short fiber-like filler.SOLUTION: A method for producing a short fiber-like filler has a grinding step for grinding, with a ball mill grinder, a fibrous filler precursor with a number average fiber length of 2 mm or more in the presence of particles with an average particle size of 10 μm or less. An abundance of the particles is 0.01 pt.mass or more and 100 pts.mass or less relative to the fibrous filler precursor 100 pts.mass. A constituent material of the particles has a Mohs hardness higher than that of a constituent material of the fibrous filler precursor.SELECTED DRAWING: None
