The invention discloses a preparation method of a bionic directional ordered laminated composite material. The preparation method comprises the following steps of: step 1. preparing frozen casting slurry, wherein the slurry comprises axanthan gum solution, polyvinyl alcohol and powder, and the powder is one or a mixture of more of metal, a metal compound and ceramic; uniformly mixing the components, and removing bubbles to obtain the frozen casting slurry; step 2. guiding the frozen casting slurry into a mold, conducting directional freezing till the surface is completely frozen to obtain solid slurry; step 3. putting the solid slurry into a pre-freezing chamber for continuous freezing, then carrying out freeze drying, and taking out to obtain an original blank; step 4. sintering the original blank to obtain a porous framework; and step 5. placing an infiltration material around the porous framework, carrying out heating infiltration, and cooling and curing at room temperature to obtain the laminated composit
