Definitions
- the present invention relates to a production method for producing a tubular body by a filament winding method (hereinafter simply referred to as “FW method”) using reinforcing fibers such as carbon fiber, glass fiber, and aramid fiber.
- FW method filament winding method
- the FW method is a method in which continuous reinforcing fibers (hereinafter simply referred to as “continuous fibers”) are impregnated with a resin, and the continuous fibers are wound around a rotating cylindrical mandrel at an appropriate winding angle and formed into a predetermined shape.
- this method is advantageous in that the strength and elastic modulus of the fiber can be drawn out to the maximum, and the lamination direction is precise and highly reliable.
- it is required to select suitably the winding angle (fiber orientation) of the fiber with respect to a mandrel. For this reason, it is advantageous if the winding angle can be arbitrarily selected within a range from 0 ° parallel to the mandrel axis to 90 ° perpendicular to the axis.
- the winding angle of continuous fibers cannot be made too low due to the problem of fiber yarn slipping, and the limit is about 30 °.

- the continuous fiber since the continuous fiber is turned in a state where the continuous fiber is hung on the pin, an extra tensile tension acts in the width direction of the continuous fiber, and as a result, the fiber width of the continuous fiber shrinks. End up. Therefore, in order to obtain a tubular body that satisfies the desired quality by heat-curing after the end of winding, it has to be cut at a position considerably inside the pin, resulting in a disadvantage that the yield is deteriorated.
- a molding method based on the FW method that does not use a non-slip jig is well known as means for enabling low-angle winding with good yield and good lamination.
- the continuous fiber 23 is directly wound around the mandrel barrel 20 with the shaft 22 integrally provided on the mandrel barrel 20 having a small diameter as much as possible.
- molding method of the tubular body using this is proposed (patent document 2).
- the object of the present invention is to prevent the shrinkage of the yarn width that occurs when the continuous fiber is folded back and improve the yield even when a tubular body is manufactured by the FW method using a non-slip jig.
- Another object of the present invention is to provide a method for manufacturing a tubular body by the FW method, which enables winding at a low angle with a good lamination state.
- the present invention employs the following means (1) to (7).

- a method for producing a tubular body wherein the tubular body is folded back in a direction.
- the folded portion includes a plurality of needle-shaped portions, and the needle of the needle-shaped portion protrudes by a length of 1 to 10% of the diameter of the mandrel barrel, and the protruding direction of the needle and the direction of the needle.
- the yarn width of the continuous fiber after being wound around the mandrel body portion contracts by a length of 10% or less of the yarn width (reference width) of the continuous fiber before being wound around the mandrel body portion.
- the yield which is defined as the ratio of the amount of fibers in the processed part (product part) and the amount of added fibers, is maintained at 90% or more by reducing the amount of fibers wound around the one end of the mandrel body (1) (6) A method for producing a tubular body.
- the “continuous fiber” means a seamless reinforcing fiber drawn from the bobbin, but if it is applied to a part unrelated to the product, a reinforcing fiber bond may be present.
- the reinforcing fiber used is preferably a high-strength, high-elasticity fiber in order to satisfy characteristics such as torsional strength and resonance frequency necessary for the torque transmission shaft using the obtained tubular body, such as carbon fiber or glass. Fibers, aramid fibers, boron fibers, ceramic fibers and the like are preferably used, and the reinforcing fibers used are not limited to one type, and may be used in combination.
- thermosetting resin such as an epoxy resin, an unsaturated epoxy resin, a phenol resin, or a vinyl ester resin is preferably used.
- an epoxy resin is particularly preferably used in consideration of the point that excellent mechanical properties can be obtained later.
- “reciprocating in parallel” means parallelism between the moving direction of the feed roller and the rotation axis direction of the mandrel body in order to wind the continuous fiber around the mandrel body with the same winding angle and the same winding tension.
- the feed roller moving direction and the rotation axis of the mandrel body portion are continuously arranged in parallel. There is no need to reciprocate the fiber.

It is done by turning in the same way. This operation is repeated a plurality of times to finish winding the desired number of windings / stacks, and then the continuous fibers 15 wound around both ends are cut and removed, and then the resin is heat-cured and then removed from the mandrel 1.
- a tubular body can be obtained by wicking.
- the needle-shaped member 16 means a member having a pointed tip, but the shape of the tip may be any shape as long as the continuous fibers 15 can be easily applied.
- the needle-shaped member 16 is easily broken, avoiding the situation that it must be frequently replaced, and when the continuous fiber 15 is wound around the mandrel 1,
- the diameter of the needle-shaped member 16 is preferably 2 to 5 mm, and more preferably 3 to 4 mm.

Even if the step (shoulder) 12 at the end of the straight portion 10 of the mandrel 1 is made to have a smooth curved surface in consideration of prevention of tearing 15, the continuous fiber 15 does not slide in the center direction of the mandrel 1, and this step 12 Since the winding can be performed while maintaining the winding angle ⁇ , the mandrel 1 may not be provided with the folding member 13.
- the winding angle ⁇ is set to 0 °. The closer the fibers are, the more the continuous fiber 15 slides toward the center of the mandrel 1.
- stable winding can be performed at any winding angle, and the yarn width can be reduced. This is particularly effective because it can prevent shrinkage and improve the yield.
- the yarn width of the continuous fiber 15 wound around the straight portion 10 of the mandrel 1 was set as a reference width, and a portion where the yarn width contracted to 10% with respect to the reference width was set as a product portion of the obtained tubular body.
- the ratio between the amount of continuous fibers and the amount of fibers used as the product part of the tubular body is defined as a yield
- the yarn width of the continuous fibers can be increased even when a folded member having a needle-shaped portion is used by using the manufacturing method described above. Since it is possible to perform favorable winding without narrowing, it is possible to reduce the amount of fibers wound around the end of the mandrel, that is, the amount of fibers that are finally cut and discarded, The yield can be increased to 90% or more.
- the tubular body manufacturing method according to the present invention can be applied to any tubular body manufacturing method used as a torque transmission shaft for vehicles, ships, helicopters, etc., and the application range is not limited thereto. .
