ll] 1'l The excellent properties such as water, alkali resistance, and blood chemistry have attracted attention, and the possibility of supplying low-grade carbon fibers has emerged, so this carbon fiber is used as a cement-based composite material. In order to use it as a composite material, short carbon fibers are used, and the practical allowable length of the fibers is considered to be about 3 to 30 mm. Currently, single fibers have a diameter of 8 to 18 microns, a specific gravity of about 1.2 to 1.9, and have the property of agglomerating into small lumps like flocs. However, it is very difficult to disperse the fibers into ball-shaped small agglomerates and single fibers. Therefore, the present applicant has proposed a method and apparatus for dispersing the aggregated short carbon fibers into single fibers in a dry state (Japanese Patent Application Laid-Open No. 58-1811).
760 (see Publication No. 760), and was able to uniformly disperse and mix carbon short fibers in various powdered raw materials in a dry state, but when the carbon short fibers exceed about 3 to 5% by weight, various powders There was a drawback that the short carbon fibers dispersed and mixed in the raw material came into contact with each other and re-agglomerated, resulting in formation of cavities.

It is possible to mix a large amount of short carbon fibers (15 to 20 parts by weight) into single fibers without re-agglomerating them by mixing them into various powdered raw materials in a state in which additives consisting of carbon fibers are interposed between the short carbon fibers. It is characterized by being able to maintain a mixed state of 11.
