▎ 摘　　要

NOVELTY - Bionic thermal insulation material comprises hollow fiber fabrics and matrix resins with voids in an orderly arrangement. The axial direction of the void is perpendicular to the thickness direction of the bionic heat insulating material. USE - The material is used in refractory material, building thermal insulation material, and aerospace thermal insulation material (claimed). ADVANTAGE - The bionic heat insulation material: has anisotropic heat-conducting coefficient; reduces the heat transferred to the material; improves the heat-insulating performance of the material; can adjust the concentration of sodium alginate; and further controls the heat conductivity coefficient and heat insulation effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of bionic heat insulating material.
