An elastic abrasive tool based on micropore silica gel was designed and reinforced with silicon carbide (SiC) particle. The abrasive internal structure presents porous chain network structure, and the enhanced particles uniformly distributed in the matrix. The compression performance of modified composites is nonlinear increasing. The experimental results show that the accumulating energy of the self microporous structure is easy to overcome the internal friction in a certain deformation quantity of the materials. When the deformation quantity is large enough, the microporous structure and the chain segment structure of the matrix silica gel affect weakened, so that the properties of the composite decreased. And there is a synergistic relationship between the particles size and the matrix silica gel. That is, when the particle size is near the silicon chain length, the effect of particle enhancement is obvious. When the particle size is small, the effect of particles was reduced because the particles are inlaid between the slots in the silicon chain. On the other hand, when the particle size is larger, the particles are not work in the composites.

The precise controllability of the elastic abrasive tool has always been a major problem in the engineering field. Based on the previous experiments, the objectives and scope of the research fit the compression controllability function equation of the elastic abrasive tool based on MATLAB software. The compression mechanics characteristics of elastic abrasives were analyzed. The reliability of the equations and the tribological properties of elastic abrasives were studied. The results show that the cell size and density of the foamed composite have a great influence on the compressive mechanical properties and tribological properties of the material. The thickness of the matrix among the holes will determine the elastic resistance of the material and the surface quality of the workpiece to be processed.
