Description

Technical field: [0001] The invention relates to the field of composite materials, in particular to a high-strength, wear-resistant and environment-friendly resin-based composite material. Background technique: [0002] Epoxy resins are an important class of thermosetting resins and are the most widely used matrix resins in polymer composites. Epoxy resin has the advantages of excellent bonding performance, electrical insulation performance, chemical stability, low shrinkage, easy processing and low cost. It is used in adhesives, electronic instruments, light industry, construction, machinery, aerospace, Coatings, electrical and electronic insulation materials and advanced composite materials have been widely used. [0003] After curing, epoxy resin has the disadvantages of large internal stress, brittle quality, poor impact resistance, crack resistance and moisture resistance, which largely limits its application in some high-tech fields. In recent years, structural bondi...
