Multi-scale three-dimensional network carbon skeleton structure auxiliary composite material and preparation method thereof
The invention belongs to the technical field of composite material preparation, and discloses a multi-scale three-dimensional network carbon skeleton structure auxiliary composite material and a preparation method thereof. The preparation method comprises the following steps: impregnating a low-density fiber preform composite material in a precursor solution to obtain an impregnated low-density fiber preform composite material; the precursor solution is a mixed solution of resorcinol, a formaldehyde solution, distilled water and hexadecyl trimethyl ammonium bromide; and carrying out curing treatment, carbonization treatment and active reaction infiltration treatment on the impregnated low-density fiber preform composite material to obtain the multi-scale three-dimensional network carbon skeleton structure auxiliary composite material. A three-dimensional network carbon skeleton structure is introduced into a low-density preform composite material, macropores are effectively divided, the capillary action is enhanced, meanwhile, molten alloy is fully reacted, residual metal in the composite material is reduced, and the grain size of a ceramic product is refined, so that the high-performance ceramic modified composite material is prepared.
本发明属于复合材料制备技术领域，公开了一种多尺度三维网络碳骨架结构辅助复合材料及其制备方法：将低密度纤维预制体复合材料在前驱体溶液中浸渍，得到浸渍后的低密度纤维预制体复合材料；前驱体溶液采用间苯二酚、甲醛溶液、蒸馏水与十六烷基三甲基溴化铵的混合液；将浸渍后的低密度纤维预制体复合材料进行固化处理、碳化处理积极反应熔渗处理，得到所述多尺度三维网络碳骨架结构辅助复合材料。本发明向低密度预制体复合材料中引入了三维网络碳骨架结构，对大孔隙进行有效划分，增强毛细作用，同时使熔融态合金充分反应，减少复合材料内部的残余金属，细化陶瓷产物的晶粒尺寸，以制备得到高性能陶瓷改性的复合材料。
