▎ 摘　　要

NOVELTY - Multiple self-repairing structure, is claimed. The structure is prepared by mixing high temperature resistant resin, thermoplastic polymer and filler according to the proportion. The structure has good toughness after curing, and it can be heated when it is damaged to generate micro-cracks, micro-crack is automatically repaired. USE - The multiple self-repairing structure is useful for brittle materials with high glass transition temperature (claimed). ADVANTAGE - The multiple self-repairing structure improves the toughness of the material, prolongs the service life of material, and increases reliability of the structure material.
