合に変形するという問題があつた。Conventional technology and its problems Conventionally, bobbins, winding cores, and container bodies have been made of paper tubes or fiber-reinforced plastics (hereinafter referred to as FRP).
Cylindrical material was used. However, in the case of paper tube materials, there has been a problem that the properties such as strength, water resistance, moisture resistance, abrasion resistance, impact resistance, gas barrier resistance, etc. are not sufficient. Further, when a paper tube material is used for a bobbin or a winding core, there is a problem in that it deforms when it is forcibly fitted onto a spindle.

てボルト等に錆が発生するという問題があつた。 On the other hand, in the case of FRP tube materials, the above-mentioned problems of paper tube materials can be solved, but they are heavy, expensive, and generate pollution due to high burn calories when burned as waste. There have been problems such as the occurrence of changes over time such as twisting and distortion in the cylindrical material due to uneven tension and uneven expansion and contraction of the fibers used as a material, insufficient heat insulation properties, and insufficient light shielding properties. In addition, if FRP tube material is used for the bobbin or winding core, it may be difficult to attach the cap, it may resonate and generate noise when it rotates, and the spindle may become deformed due to the above-mentioned changes over time or winding pressure. There was a problem in that it could not be mounted, and that it could not be mounted on the spindle if there was a dimensional error in the tube material or the spindle. Furthermore, if FRP tubing material is used for the body of a container containing bolts, nuts, nails, wound metal wires, etc., the bolts will become wedged inside the body due to local contact pressure, causing cracks during transportation. There is a risk of cracking due to impact, and the contents may be damaged.
Another problem was that the insulation was insufficient, causing condensation on the inner surface and rusting on bolts and the like.

られているものである。Means for Solving the Problems The composite cylindrical material according to the present invention comprises an inner layer made of paper and an outer layer made of fiber-reinforced plastic formed by wrapping a resin-impregnated fiber reinforcing material around the outer periphery of the inner layer and curing the resin. A resin permeation suppressing paper is interposed between the inner layer and the outer layer to prevent resin from permeating into the inner layer, and a part of the resin constituting the outer layer is allowed to penetrate and harden through the resin permeation suppressing paper.
By adhering the resin penetration suppressing paper to the inner layer,
The inner layer and the outer layer are adhered to each other with a resin permeation suppressing paper interposed therebetween.

The thickness of the inner layer is appropriately determined in consideration of the use of the composite tube material. The thickness of the inner layer can be changed by changing the thickness of paperboard, kraft paper, paper tube base paper, etc., or by changing the number of turns, that is, whether it is wound once or twice or more. When wrapping paper more than twice,
It is preferable to bond paper strips adjacent to each other in the inner and outer directions with adhesive. This adhesion can be achieved by applying a liquid adhesive to the paper before wrapping it around the mandrel, and by interposing a film adhesive between two or more paper strips, or by applying a film adhesive to the surface of the paper strip. This is done by coating the paper strip with a hot-melt adhesive or by laminating a film adhesive on the surface of the paper strip, and heating it at the same time as the thermosetting resin that forms the FRP layer. Water wet again,
In order to prevent the inner layer from changing over time due to humidity changes, temperature changes, etc., the inner peripheral surface of the inner layer may be covered with a synthetic resin coating layer. This resin coating layer is formed by placing a plastic film, laminated paper, resin dip paper, etc. on the inner peripheral surface of the inner layer. That is, before spirally winding the innermost paper in the inner layer, the above-mentioned plastic film or the like may be wound around a mandrel in advance.

れる。 As the fiber reinforcing material in the FRP outer layer, synthetic resin fibers such as polyester fibers and Tetron fibers, glass fibers, carbon fibers, boron fibers, and cloth, roving, pine, and blind weaves are used. The FRP outer layer is formed using a thermosetting resin such as unsaturated polyester resin, epoxy resin, vinyl ester resin, or polyimide resin. The FRP outer layer is formed by spirally wrapping one or more strips of fiber reinforcement impregnated with thermosetting resin around a cylindrical paper inner layer, and then heating to harden the resin. Ru. In addition, if at least one fiber reinforcement material or the thermosetting resin impregnated with at least one reinforcement material is colored, the resulting colored pattern can be used for bobbins, winding cores, container bodies, etc. This makes it possible to identify them. The thickness of the outer layer is
It is determined mainly by considering the strength, depending on the use of the tube material.

い。 Resin penetration suppressing paper, which prevents resin penetration into the inner layer, allows thermosetting resin to penetrate into itself, but
This paper has a slow rate of resin penetration, and does not allow the resin to reach the paperboard or the like that makes up the inner layer before the thermosetting resin hardens. Examples of such paper include liner paper, laminate paper with a paper/film/paper structure, glassine paper, parchment paper, and wrapping paper. Among the above papers, liner paper is preferably used with the surface layer facing outward.

If this is done, the above-mentioned problem when using the FRP tube material for the bobbin will be solved.
The thickness of the FRP outer layer at this time depends on the strength, weight and overall wall thickness required for the bobbin, the type of thread wound around the bobbin, and the type and use of reinforcing material used for the outer layer of the tube material. It is determined by taking into account the type of thermosetting resin used. In addition, when the tube material of this invention is used for the body of a container, its inner diameter is at most 700 mm.

を一挙に解決することができる。Effects of the Invention The composite tube material according to the present invention has an inner layer made of paper and an outer layer made of fiber-reinforced plastic. A fiber used as a reinforcing material that has excellent performance such as strength and gas barrier properties, and is also light in weight and low cost due to the presence of an inner layer, and has a low calorie burn during waste combustion, which can prevent pollution. Even if changes over time such as twisting or distortion occur in the outer layer due to uneven tension or expansion/contraction, the inner layer can absorb it, and the insulation is sufficient.
It also has the effect of providing sufficient light-shielding properties.
Furthermore, the inner layer improves performance such as shock absorption, sound absorption, and deformation absorption. Therefore, the problems of the paper tube material and the FRP tube material described above can be solved all at once.

題が生じることがあるが、これも防止される。 In addition, resin permeation suppressing paper is glued between the inner layer and the outer layer to prevent the resin from permeating into the inner layer, so the thermosetting resin impregnated into the fiber reinforcement material can This prevents it from penetrating into paperboard, etc. As a result, it is possible to prevent air bubbles from forming partially at the boundary between the inner and outer layers after the thermosetting resin has cured, and to prevent air bubbles from forming within the outer layer.
This prevents a decrease in the strength of the outer layer and peeling of the inner and outer layers due to the presence of air bubbles. moreover,
If the degree of penetration of the resin is severe, the thermosetting resin may reach the inner circumferential surface of the inner layer, causing the same problem as the FRP tube material, but this is also prevented.

である。 In addition, a part of the resin constituting the outer layer is penetrated and hardened by the resin permeation suppressing paper, and the resin permeation suppressing paper is adhered to the inner layer, so that the inner layer and the outer layer are fixed together via the resin permeation suppressing paper. Therefore, even when this cylindrical material is used for a bobbin, winding core, etc. and attached to a spindle, there is no risk of the inner layer and outer layer slipping. Furthermore, when used on the body of a container, the top cover, bottom cover, etc. can be easily and reliably attached. If the inner layer and outer layer are not firmly attached, it will be difficult to attach the top cover, bottom cover, etc.
