This invention discloses a hot-press curing method and system for carbon fiber rigid felt, relating to the field of carbon fiber rigid felt preparation technology. Its main objective is to avoid the threat to safe production posed by mixed gases containing VOCs during the hot-press curing process of carbon fiber rigid felt, and to reduce the amount of exhaust gas emitted. The main technical solution of this invention is: a hot-press curing method for carbon fiber rigid felt, comprising the following steps: Step S1, sealing the hot press and purging it with inert gas; Step S2, performing the hot-press curing process under inert gas protection, recovering alcohol; Step S3, performing the hot-press curing process in a dust-free environment and explosion-proof atmosphere, recovering waste liquid; Step S4, releasing the seal of the hot press to obtain the carbon fiber hot-press cured felt.
