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 is applicable to liquid molding manufacture of thermosetting resins, liquid molding and toughening of thermosetting composite materials, and liquid molding manufacture of thermoplastic composite materials. By means of the “ex-situ” liquid molding, some resin materials originally unsuitable for liquid molding can be modified into liquid-moldable materials, thereby expanding the options and types of resin materials for liquid molding.
