うことにより複合筒材（１）が製造される。First, the strip-shaped laminated paper (9) is spirally wound around the outer peripheral surface of the mandrel (M) so that the polyethylene film or the like is placed inside. An outer fold portion (9a) is previously provided at one side edge of the strip-shaped laminated paper (9) by using a folding device (11) to expose the polyethylene film to the outside, and the strip-shaped laminated paper ( 9) The outer surface of the folded portion (9a) and the inner surface of the other side edge portion of the strip-shaped laminated paper (9), that is, the polyethylene films are overlapped with each other at the joint portion. Then, the overlapping portion is heat-sealed. This heat sealing is performed simultaneously with the heating of the thermosetting resin described later. Then, the adhesive is applied by passing the four strips of paperboard (5) through the adhesive applying tank (12), and then the adhesive-applied 4
A strip of paperboard (5) is wound in a spiral shape on the laminated paper (9) wound in sequence on the mandrel (M) and adhered to each other with an adhesive to form the inner layer (2). . Then, the strip-shaped laminated paper (6) is spirally wound around the inner layer (2) consisting of the four-layer paperboard (5) wound around the mandrel (M), and the outermost peripheral paperboard (5 ) Adhere to. The inner layer (2) and the laminated paper (6) can be moved to the right in FIG. 3 while being rotated by a known belt driving device (not shown) or the like. Then consists of glass fiber roving 3
After one strip-shaped reinforcing material (8) is impregnated with the unsaturated polyester resin in the unsaturated polyester resin holding tank (13), the resin-impregnated reinforcing material (8) is sequentially applied to the laminated paper (6). Wrap it spirally on top. The amount of the resin impregnated in the reinforcing material (8) is set such that the reinforcing material (8) is not exposed from the outer peripheral surface of the plastic layer (7) when the resin is cured in the subsequent step. The resin impregnated in the reinforcing material (8) penetrates the laminated paper (6), but does not reach the inner layer (2). Next, a release tape (14) made of paper, a plastic film or the like for preventing the resin from dripping is spirally wound around the resin-impregnated reinforcing material (8) layer. After winding the release tape (14), the release tape (14) is passed through a heating and drying device (15) to cure the unsaturated polyester resin to form the outer layer (3), and the joint between the laminated papers (9). Heat seal. At this time, the unsaturated polyester resin that has penetrated into the laminated paper (6) is also cured so that the laminated paper (6) and the outer layer (3) are fixed, whereby the laminated paper (6) adhered to the inner layer (2). ), Both the inner and outer layers (2) and (3) are fixed. After that, the composite tubular material (1) is manufactured by cutting it to a predetermined length with a cutter such as a cutter, peeling off the release tape (14), and finishing the surface.

経時変化が起こるのを防ぐことができる。EFFECTS OF THE INVENTION The composite tubular material according to the present invention includes a paper inner layer, a fiber reinforced plastic outer layer, and a plastic coating layer that covers the inner peripheral surface of the inner layer. It has excellent properties such as moisture resistance, wear resistance and impact resistance, overall strength and gas barrier property, and the existence of the inner layer makes it small in weight, low in cost, and low in fuel calories during waste combustion. Can prevent pollution, can be absorbed in the inner layer even if the outer layer is twisted or distorted due to uneven tension or expansion / contraction of the fiber used as a reinforcing material, has sufficient heat insulation, and has light-shielding properties. Has the effect of being sufficient. Furthermore, the inner layer improves performances such as impact absorption, sound absorption, and deformation absorption. Therefore, it is possible to solve all the problems of the above-described paper-made tubular material and FRP-made tubular material. Moreover, the presence of the plastic coating layer can prevent the inner layer from absorbing water. Therefore, it is possible to prevent the inner layer from changing over time due to water absorption.

ことがあるが、これも防止される。Further, since the resin permeation suppression paper that prevents the permeation of the resin into the inner layer is interposed between the inner layer and the outer layer, before the thermosetting resin impregnated in the fiber reinforcing material is cured, its inner side is cured. It will be prevented from penetrating into the paperboard. as a result,
After the thermosetting resin is cured, voids are partially formed at the boundary between the inner and outer layers, and bubbles are prevented from being generated in the outer layer, and the strength of the outer layer is reduced due to the presence of the voids and bubbles, and the inner layer is It prevents the peeling from the outer layer from occurring. Further, if the degree of penetration of the resin is high, the thermosetting resin may reach the inner peripheral surface of the inner layer, which may cause the same problem as in the FRP tubular material, but this is also prevented.

れていないと、頂蓋、底蓋等の取付けが困難である。Furthermore, a part of the resin constituting the outer layer is permeated and cured into the resin permeation suppression paper, and the resin permeation suppression paper is adhered to the inner layer, so that the inner layer and the outer layer are fixed via the resin permeation suppression paper. Therefore, even when this tubular member is used as a bobbin, a winding core, or the like and mounted on a spindle, there is no risk of slipping between the inner layer and the outer layer. Furthermore, when it is used for the body of a container, the top lid, the bottom lid, etc. can be easily and surely attached. If the inner layer and the outer layer are not firmly fixed to each other, it is difficult to attach the top lid and the bottom lid.
