てボルト等に錆が発生するという問題があった。BACKGROUND ART Conventionally, paper tube materials and fiber reinforced plastic (hereinafter referred to as FRP) tube materials have been used for bobbins, winding cores, and container bodies. However, in the case of paper tube materials, there has been a problem that the properties such as strength, water resistance, moisture resistance, 1f abrasion resistance, impact resistance, gas barrier resistance, etc. are not sufficient. Furthermore, 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. Also, F
In the case of RP tube material, the above-mentioned problems of paper tube material can be solved, but it takes a long time, is expensive, and generates pollution due to high combustion power during waste combustion. There are problems such as the uneven tension and uneven expansion and contraction of the fibers used as reinforcing materials before the resin hardens, causing changes over time such as twisting and distortion in the cylindrical material, insufficient heat insulation, and insufficient light shielding properties. there were. In addition, when used for FRP tubing bins or winding cores, it may be difficult to attach the cap, resonance may occur during rotation, and noise may occur, and the spindle may become deformed due to aging or winding weight. There have been problems in that it cannot be mounted on the spindle if there is a dimensional error in the tube material or the spindle. Generally speaking, when used in the body of a container containing FRP pipes such as bolts, nuts, nails, and wound metal wires, the bolts, etc. may become wedged inside the body due to local contact pressure, causing cracks during transportation. There was a problem that the contents could be damaged due to impact such as, etc., and that the insulation was insufficient and condensation formed on the inner surface, causing rust on bolts and the like.

と同時に加熱することにより行なう。In the above, the paper inner layer is formed, for example, by spirally winding a strip of paperboard, kraft paper, paper tube base paper, etc. around a mandrel. The thickness of the inner layer is determined as appropriate 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 simultaneously with the thermosetting resin that forms the FRP layer.

る。As the fiber reinforcing material in the FRP outer layer, synthetic resin fibers such as polyester TI1M and Tetron fibers, cloths, rovings, mats, and blind weaves such as glass fibers, carbon fibers, and boron fibers are used. FRP
The outer layer is formed using a thermosetting resin such as an unsaturated polyester resin, an epoxy resin, a vinyl ester resin, or a polyimide resin. The FRP outer layer is formed by spirally wrapping one or more strip-shaped fiber reinforcing materials 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 determined depending on the use of the cylindrical material, mainly considering strength.

ィルム等をマンドレルに巻いておけばよい。The plastic covering layer is for preventing the inner layer from deteriorating over time due to wetting with water, changes in humidity, and the like. This coating layer is formed by placing a plastic film, laminated paper, resin-dipped paper, etc. on the inner peripheral surface of the inner layer. For example, before spirally winding the innermost paper in the inner layer, the plastic film or the like may be previously wound around a mandrel.

側に向けて用いるのがよい。In addition, the thermosetting resin is infiltrated into the outermost part of the inner layer, but the degree of penetration of the resin is slow, and there is paper that prevents the resin from reaching the inner paperboard etc. before the thermosetting resin hardens. It's good to keep it. Such papers include, for example, liner papers, laminates with a paper/film/paper structure,
Glassine paper, parchment paper, wrapping paper, etc. are used. Among the above papers, liner paper is preferably used with the surface layer facing outward.

ることがある。If you insert paper like the one above on the outermost part of the inner layer,
This prevents the thermosetting resin impregnated into the fiber reinforcing material from penetrating into the paperboard or the like inside the fiber reinforcing material before it hardens. As a result, after the thermosetting resin is cured, voids are prevented from forming partially at the boundary between the inner and outer layers, and air bubbles are prevented from forming within the outer layer, and the strength of the outer layer is prevented from decreasing due to the presence of the voids and air bubbles. This prevents delamination between the inner layer and the outer layer. Furthermore, 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 that of the FRP tube material.
また、内層の最外周部に位置する上記のような紙は、こ

種類等を考慮して決定される。When the cylindrical material of the present invention is used for a bobbin, its inner diameter is usually about 10 to 1,551 m, and in that case, the thickness of the paper inner layer is preferably at least 2 ml11. If this is done, the above-mentioned problems 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.

By doing this, the problem when using FRI"A cylinder material as described above for the container will be solved.In addition, at this time, the FRP
The thickness of the outer layer depends on the strength and weight required for the bobbin.
It is determined by taking into account the type of reinforcing material used for the outer layer, the type of thermosetting resin used for the outer layer, the type of items to be placed in the container, etc.

有する問題点を一挙に解決することができる。Effects of the Invention The composite cylindrical material according to the present invention is composed of an inner layer made of paper, an outer layer made of fiber-reinforced plastic, and a plastic coating layer that covers the inner circumferential surface of the inner layer, and the outer circumferential surface of the inner layer and the inner circumferential surface of the outer layer are in close contact with each other. Because of the outer layer, the outer surface has excellent water resistance, moisture resistance, abrasion resistance, impact resistance, overall strength, and gas barrier resistance, and the inner layer also reduces weight. Small size, low cost, low calorie combustion during waste combustion to prevent pollution. 1M used as reinforcing material. Due to uneven tension and uneven expansion and contraction of the outer layer, changes over time such as twisting and distortion occur in the outer layer. It has the effects of being able to absorb even the most intense heat in the inner layer, having sufficient heat insulation properties, and having sufficient light blocking properties. Furthermore, the inner layer improves performance such as shock absorption, sound absorption, and deformation absorption. Therefore, the problems of the above-mentioned paper tube material and FRP tube material can be solved all at once.
