<正>Caged bicyclic phosphate(CBP)and its dimelamine salt(PDS)were synthesized and added to epoxy resins to obtain the flame retarded epoxy resin composites.The flammability of the composites was characterized by the limiting oxygen index(LOI)and cone calorimeter tests.The LOI values of flame retarded composites increase consistently with the increase of flame retardant amounts
