Abstract
Provided are a rubber composition provided with excellent reinforcement properties by improving the dispersibility of fibers in a rubber component when the fibers are added to the rubber, a method for manufacturing the same, a vulcanized rubber, and a tire. A rubber composition comprising a rubber component and short fibers, wherein the short fibers are cationized. A method for manufacturing the rubber composition, comprising a mixing step for mixing cationized short fibers and rubber latex to prepare a rubber-short fiber mixed solution, and a drying step for drying the rubber-short fiber mixed solution to give a rubber composition.
