There are provided a method of producing reclaimed carbon fibers in which, even if a carbon fiber reinforced resin is not heated at 800&#xb0; C. or higher, pieces of carbon fiber base material that are contained in the carbon fiber reinforced resin can be directly collected, and the variation in the resin residue content in the collected pieces of carbon fiber base material can be reduced, a device for producing reclaimed carbon fibers that can be used in the production method, and a method of producing a carbon fiber reinforced resin in which reclaimed carbon fibers can be effectively used. A method of producing reclaimed carbon fiber bundles which is a method of obtaining pieces of carbon fiber base material as reclaimed carbon fiber bundles from a carbon fiber reinforced resin () containing a plurality of sheet-like pieces of carbon fiber base material and a matrix resin, including heating the carbon fiber reinforced resin () and thermally decomposing the matrix resin to obtain a heat-treated product (); and crushing the heat-treated product () and separating the plurality of pieces of carbon fiber base material into individual reclaimed carbon fiber bundles.

Method of producing reclaimed carbon fiber bundles, reclaimed carbon fibers, or reclaimed milled carbon fibers, device for producing reclaimed carbon fiber bundles, method of producing carbon fiber reinforced resin, and reclaimed carbon fiber bundles

A gas-containing base material including a functional-gas-containing composition, where the composition is a gel-like composition having a gelation temperature in a range of 0.5&#xb0; C. or higher and 65&#xb0; C. or lower at which a liquid form is able to be changed to a solid form by cooling, and where the composition contains an amount of a bubble state functional gas which exceeds a saturated solubility when the composition is in a liquid form.
