Abstract
Embodiments of the present disclosure provide an ex-situ preparation method for a composite molded body. The preparation method comprises: providing a porous support, a first component, and a second liquid component; contacting the first component with the porous support; contacting the second liquid component with the first component and/or the porous support, in which process the first component and the second liquid component do not undergo a chemical reaction, and the second liquid component remains in a liquid state; and treating the first component and the second liquid component such that the first component and the second liquid component undergo a chemical reaction to become a solid, or undergo phase transformation toughening and solidification molding. The present disclosure discloses an advanced composite material manufacturing technology, and relates to a low-cost and easy-to-operate ex-situ liquid molding preparation method. In the method, core reaction components are separated spatially, and two sub-processes of physical flow and chemical reaction are separated chronologically, thereby greatly simplifying the liquid molding technique. The “ex-situ” preparation method …
