发明名称 COMPOSITE PIPE AND A PRODUCTION METHOD THEREFOR
摘要 The present invention relates to a composite pipe and to a production method therefor. The composite pipe according to the present invention comprises: a first pipe; and a second pipe which is inserted in the first pipe and is attached to the first pipe, and the second pipe comprises a plurality of ceramic tiles consisting of a ceramic material. The composite pipe production method according to the present invention comprises the steps of: subjecting the outer circumferential surface of a mandrel to a mould-release treatment; coating the outer circumferential surface of the mandrel with an adhesive; forming a second pipe by attaching a plurality of ceramic tiles to the outer circumferential surface of the mandrel so as to cover the outer circumferential surface of the mandrel; coating the outer circumferential surface of the second pipe with an adhesive; winding a plurality of turns of a continuous fibre, which has been impregnated with a resin, onto the outer circumferential surface of the second pipe which was coated with the adhesive, using a filament winding method; forming a first pipe by curing the resin stuck to the wound continuous fibre; and separating the mandrel from the second pipe. The present invention provides a composite pipe having outstanding wear resistance.
