Corn stalk fiber reinforced fraction material and preparation method thereof

The invention relates to a corn stalk fiber reinforced fraction material and a preparation method thereof, and belongs to the technical field of a braking friction material. The braking friction material is prepared from the following two ingredients in percentage by mass: 11 to 24 percent of fiber space reticular composite structures and 76 to 89 percent of filling materials, wherein the fiber space reticular composite structure consists of a framework and uniformly distributed spherical cavities; the filling materials are sufficiently filled into the spherical cavity of a fiber space reticular structure. The friction material is prepared in a mode of combining the measures of modifying the friction material ingredients, optimizing the ingredient structures, designing the material integral structures and improving the technical flow process. The process relates to the preparation of corn stalk fiber of a simulated bur structure, preparation of a fiber space reticular composite structure, and formation of the
