| description | The invention relates to an epoxy resin composition and a composite material thereof, and belongs to the technical field of epoxy resins. The technical problem to be solved by the invention is to provide an epoxy resin composition, which is long in operable time and can be rapidly cured. The epoxy resin composition comprises a component A, a component B and a component C, wherein the component A is a liquid epoxy resin component, the component B is a curing agent, and the component C is an accelerant. According to the invention, the epoxy resin composition can replace an epoxy-amine resin system, so that the cost of the epoxy resin composition is reduced, and the epoxy resin composition has very good economical efficiency; and the epoxy resin composition has the characteristic of rapid curing, the gelation time at 150 DEG C is less than 40 seconds, the curing time at 70 DEG C is less than 200 minutes, the epoxy resin composition is suitable for preparing composite material parts by a vacuum infusion process, |
