Claims7
A mandrel around which fiber-reinforced resin is wound, the mandrel comprising:
- a cylinder portion that has a plurality of first flat surfaces;
- and
- a pair of dome portions that are formed at respective ends of the cylinder portion and each have a plurality of second flat surfaces,
- wherein the first flat surfaces and the second flat surfaces are discontinuous with each other.
A test piece collecting method of collecting a test piece made from a fiber-reinforced resin wound around a mandrel including a cylinder portion that has a plurality of first flat surfaces;
- and a pair of dome portions that are formed at respective ends of the cylinder portion and each have a plurality of second flat surfaces with the first flat surfaces and the second flat surfaces being discontinuous with each other, the test piece collecting method comprising:
- a layering step of winding the fiber-reinforced resin having a belt shape around the cylinder portion and the dome portions, to form a layered body in which the fiber-reinforced resin is layered;
- a curing step of curing the layered body;
- and
- a collecting step of collecting a test piece from each of a region of the layered body covering one of the first flat surfaces and a region of the layered body covering one of the second flat surfaces.
