DISASSEMBLY METHOD AND DISASSEMBLY APPARATUS FOR MANDREL USED IN PRODUCTION OF COMPOSITE MATERIAL STRUCTURE

摘要

Disclosed is a technique that can easily and efficiently disassemble a mandrel with a roughly cylindrical structure that is dividable into a plurality of segments. A rotating process for rotating a pair of support rings in a manner such that one segment, which is the target of removal, is positioned on top and a segment removing process for removing the aforementioned segment to be removed that has been positioned on top from the pair of support rings are performed on a mandrel in which a composite structure has been formed in close contact with the outer peripheral surface. In the segment removing process, the segment to be removed is vertically lowered between the pair of support rings and positioned in the interior of the aforementioned mandrel, and is subsequently removed from between the pair of support rings.
