Abstract: Purposes of the present invention are to provide a carbon-fiber-containing concrete or mortar composition which has excellent handleability due to a reinforcement produced from precut raw-material carbon fibers, such as short fibers, scrap fibers resulting from processes, or carbon fibers reclaimed from CFRPs, etc., and to provide a carbon-fiber-reinforced concrete or mortar structure which is a cured object formed from the carbon-fiber-containing concrete or mortar composition and in which the fibers have a high reinforcing effect. This carbon-fiber-containing concrete or mortar composition includes carbon-fiber masses each configured at least from carbon fibers and a binder, and is characterized in that the carbon-fiber masses each have the shape of a spindle.

Abstract: The present invention relates to a carbon fiber aggregate exhibiting improved feed properties, comprising carbon fibers and a binder. A manufacturing method of a spindle-shaped aggregate includes: providing a mixture composed of at least carbon fibers and a binder-containing liquid; manufacturing a spindle-shaped precursor by tumbling the mixture in a container; and drying the precursor.

Abstract: The present disclosure relates to a method for decomposing a plastic-containing material which makes it possible to stably and efficiently decompose a plastic-containing material, and a method for recovering an inorganic material, as well as a regenerated carbon fiber and a method for producing the regenerated carbon fiber. The present disclosure also relates to a blended spun yarn comprising a regenerated carbon fiber, a carbon-fiber-reinforced thermoplastic resin pellet comprising the blended spun yarn, and a method for producing them, a carbon-fiber-reinforced thermoplastic resin strand and a method for producing the same, and a carbon-fiber-reinforced thermoplastic pellet.
