The invention discloses a combined type buckle arrestor for a fiber-reinforced composite flexible pipe. The combined type buckle arrestor comprises a metal outer lantern ring and a fiber-reinforced inner lantern ring; the metal outer lantern ring comprises a main lantern ring body, a locking lantern ring body and an elastic seal gasket; the fiber-reinforced inner lantern ring comprises a fiber-reinforced layer and a base body protection layer; the fiber-reinforced inner lantern ring is located on the outer side of the composite pipe and bonded with the composite pipe in a hot-melting mode, thus, the pipe is locally thickened so as to achieving promoting of buckling resistant capacity; and the metal outer lantern ring wraps the fiber-reinforced inner lantern ring in an interference fit modeso that the fiber-reinforced inner lantern ring can be assisted in achieving of buckling arresting, and meanwhile, the composite pipe can be prevented from being bent excessively by means of the gooddeformation resistant performance of the metal outer lantern ring, so that stress concentration of the fiber-reinforced inner lantern ring is reduced. The bonding characteristic of materials of the composite pipe is reasonably utilized to achieve machining of the fiber-reinforced inner lantern ring, and the fiber-reinforced inner lantern ring is assisted by the metal outer lantern ring so as to improve the local structural strength; and the combined type buckle arrestor has the advantages of both a steel pipe welding type buckle arrestor and a steel pipe buckling-pressing type buckle arrestorand has wide popularization value and practical value.
