Epoxy resin combination, composite material and preparation method thereof
2008
The application discloses an epoxy resin composition, a composite material and a preparation method thereof. The epoxy resin composition provided by the application comprises epoxy resin, small molecular compounds with one or a plurality of epoxy groups, as well as amine curing agents. The application has the advantages that high-performance epoxy resin is prepared by a method of blending and modifying common epoxy resin and adding additives, and a high-performance epoxy resin-based composite material is prepared by compounding epoxy resin with reinforcing material through a liquid composite molding process. The composite material has the advantages of simple preparation process and low price, and is beneficial to large amounts of popularization and industrialization. In addition, the composite material can also be used in automobile, ship, wind power blade and other civil composite material fields, can greatly reduce manufacturing cost, and can promote technical and industrial upgrading.
