The invention provides reaction injection pultrusion equipment and a reaction injection pultrusion method for solving the problems of weak fiber dipping effect and volatilization of poisonous gas in a traditional composite material pultrusion technology. The reaction injection pultrusion equipment comprises a forming unit for forming resins and fibers; the forming unit includes the following at least four machining sections connected in sequence: a preheating section for preheating the fibers, a dipping section for dipping the resins and the preheated fibers, a heating section for curing the resins, and a cooling section for cooling a cured composite material for formation; and the machining sections form a closed machining channel with two ports. The pultrusion method and the corresponding reaction injection pultrusion equipment can realize online resin mixing and fiber dipping, have such advantages as good dipping effect and no volatilization of poisonous gas, and prepare high-fiber content continuous fiber
