Description

technical field [0001] The invention relates to a composite material, in particular to an epoxy resin composite material. Background technique [0002] Epoxy resins generally refer to organic compounds containing two or more active epoxy groups in the molecule, which can cross-link with various types of curing agents to form insoluble and infusible three-dimensional network structures. polymers. With excellent electrical insulation, mechanical, bonding, chemical corrosion resistance and good physical and chemical properties, it is widely used as laminates, adhesives, coatings, etc., and is more and more popular in the fields of ships, automobiles, aerospace, etc. Pay attention to. [0003] At present, epoxy resin is used as the matrix of composite materials, showing many problems, such as low hardness, poor insulation, softening by heat, easy delamination, difficult mass and heat transfer, and strong odor. It is necessary to improve the preparation process of epoxy resin ...
