Abstract
A method of producing a carbon fiber composite resin material including (a) a first mixing step, (b) a second mixing step, and (c) a step of curing a second mixture. In the first mixing step (a), an epoxy resin is mixed with an epoxidized elastomer to obtain a first mixture. In the second mixing step (b), vapor-grown carbon fibers having an average diameter of 20 to 200 nm and an average length of 5 to 20 micrometers are mixed with the first mixture to obtain a second mixture in which the vapor-grown carbon fibers are dispersed. In the step (c) of curing the second mixture, the second mixture is cured to obtain a highly rigid carbon fiber composite resin material.
