The invention relates to a
silicon carbide / resin bionic
composite material with a directional
microstructure, and a preparation method thereof. The
composite material is prepared from
silicon carbideof which the
volume fraction is 10-95%, and resin, and microscopically has the directional
microstructure so as to be shown in a way that
silicon carbide is directionally arranged in a
resin matrix. The preparation method comprises the following steps: firstly, preparing water base
slurry which contains
silicon carbide powder; then, through freezing
casting and vacuum freezing
drying, obtaining ablank with a directional porous structure; carrying out compressing on the blank, removing organic matters, and
sintering to obtain the directional porous skeleton of
silicon carbide; carrying out
surface modification and
liquid resin monomer impregnation on the skeleton, and obtaining the
silicon carbide / resin bionic
composite material with the directional
microstructure after resin aggregationis carried out. The composite material has excellent performances of light weight, high strength, abrasion resistance and the like, the
plasticity, the
toughness and the
impact resistance of the composite material are obviously improved than that of silicon
carbide, and therefore, the silicon carbide / resin bionic composite material is expected to serve as a
structural material to be used in fields including armor protection, transportation, electronic products and the like.
