The invention relates to a rapidly-cured halogen-free flame-retardant epoxy resin composition as well as a preparation method and application thereof. The halogen-free flame-retardant epoxy resin composition comprises a component A and a component B, wherein the component A comprises an epoxy compound and an optional reactive diluent; the component B comprises an amine curing agent and a phosphorus-containing flame retardant. The epoxy resin composition is low in viscosity, can be rapidly cured and is suitable for fiber reinforced composite material liquid forming processes such as a high-pressure resin transfer molding process (HP-RTM) or a wet molding process (WCM), and a fiber reinforced composite material prepared from the epoxy resin composition has excellent flame retardant property and mechanical property. The preparation method of the epoxy resin composition has the advantages of simple process and convenience in operation.
