Particle-containing fiber bundle production method and particle-containing fiber bundle

Abstract

A particle-containing fiber bundle having high uniformity and further improved feed efficiency, and a production method of the same are provided. The particle-containing fiber bundle production method of the present invention is for producing a particle-containing fiber bundle having a prolate spheroidal shape or a strand shape, the production method including a step of mixing a plurality of shortened fibers, particles having a median diameter of 100 μm or less, an organic binder, and a liquid, in which the fibers include carbon fibers, and the particles are used in an amount of 10 parts by mass or more with respect to 100 parts by mass of the fibers.
