Method for preparing carbon/carbon composite materials through 3D printing
The invention relates to a method for preparing carbon/carbon composite materials through 3D printing. The method comprises the steps that after being etched with an etching solution, carbon fibers are mixed with a solvent used for dissolving thermosetting resin to obtain a solid and liquid mixture; the thermosetting resin and a curing agent are fully mixed to obtain a solid mixture; the solid and liquid mixture and the solid mixture are added in a reaction vessel, and after the solid mixture is stirred and dissolved, a mixture block obtained by drying the mixtures in the reaction vessel is crushed; prepared raw materials are poured in a 3D printer powder feeding cylinder for carbon/carbon composite material green body 3D printing; and an obtained carbon/carbon composite material green body is put in a heat treatment furnace to be cured, carbonized and densified to obtain the carbon/carbon composite materials. The carbon/carbon composite materials prepared through the method have the excellent mechanical performance and technological forming performance, and application of the carbon/carbon composite materials is widened to the field of more precise and complex structures.
