Beschreibung
Zusammenfassung:	The invention discloses an apparatus for demolding composite pipes from mandrels and method thereof. The apparatus and method comprise the steps of: firstly, a circular jig is fixed on one end of a mandrel. Then, the composite pipe billet is formed on the mandrel, wherein the composite pipe billet has a circular part, and the circular part is formed against the circular jig. Further, the composite pipe billet is oven-cured. After curing, a demolding plate is set on the mandrel. Then, a demolding machine is used to release the composite pipe billet from the mandrel by withdrawing the mandrel from the composite pipe billet. Finally, the circular jig is demolded from the mandrel firstly, and the circular part is cut to complete the composite pipe billet product.
