Preparation method of structural biomass-based silicon-carbon pipe material

The invention discloses a preparation method of a structural biomass-based silicon-carbon pipe material, which comprises a silicon-carbon material subjected to reactive twin-screw processing when being blended with a high-molecular polymer, so that the material can obtain better plasticizing effect in the polymer, and meanwhile, concave-convex particles are uniformly dispersed in the polymer underthe action of twin-screw shearing force. The silicon-carbon composite material has the advantages that the particles are changed into finer short fibers, the short fibers form staggered shapes underthe action of buoyancy, and the structure of the short fibers is similar to a "#"-shaped arrangement; accordingly, excellent toughening effects can be realized, functional reinforcing and toughening effects can be realized in blending procedures of the silicon-carbon composite material and high polymers; due to the fiber micropore junction characteristics of silicon-carbon materials, the fiber pore channels of the particle
