する方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite cylinder of FRP and metal, which is suitable for constituting an industrial FRP roll for conveying a sheet-like material such as film, paper and cloth. The present invention also relates to a method of manufacturing such a composite cylinder.

すい。By the way, an industrial roll is required to have excellent surface abrasion resistance because it comes into contact with a sheet-like material such as a high-speed film, paper or cloth. In this respect, aside from the metal roll, the FRP roll is not so high in abrasion resistance because FRP has a resin as its constituent element. Therefore, a metal plating film is formed on the surface as described in Japanese Utility Model Publication No. 32-32431, or the method disclosed in JP-A-61-61
As described in JP-A-217566, a metal spray coating is formed to improve wear resistance.
Even if these coatings are formed directly on the surface of FRP which is essentially a resin, the adhesiveness of the coatings is weak and peeling or cracking is likely to occur.

したり筒軸方向にずれたりするのである。On the other hand, there is also proposed an industrial roll in which an FRP inner cylinder is covered with a metal outer cylinder, and the outer cylinder is provided with a metal plating coating or a metal spray coating. In this roll, the coating is formed on the metal outer cylinder,
The adhesive strength of the coating is stronger than that described above, and peeling and cracking are less likely to occur. On the other hand, on the other hand, there is a problem that the inner cylinder and the outer cylinder are loosely connected during use, and in a remarkable case, the outer cylinder idles or shifts in the cylinder axis direction. This is because the industrial roll is generally accompanied by a temperature rise due to contact with a sheet-like material or an atmosphere during use, but since the coefficient of thermal expansion of FRP and metal is significantly different, the outer cylinder is better than the inner cylinder. This is because it expands greatly. However, even if the conventional roll is loosely coupled, there is nothing mechanically restraining the looseness, so that in a remarkable case, the outer cylinder runs idle or shifts in the cylinder axis direction.

However, such a problem is not limited to the industrial roll, and the FRP inner cylinder and the metal can be used. It goes without saying that this can occur in common in a composite cylinder having an outer cylinder.

Further, depending on the use and the like, it is also preferable that a coating film is formed on the outer surface of the outer cylinder by plating or thermal spraying.

The two are wound so that they are combined so that the angle becomes 0 ° or less, if necessary, and the wound body 2 which will later form the inner cylinder is formed. At this time, it is preferable to slightly taper the insertion side as shown in the drawing so that it can be easily inserted into the outer cylinder later. In this insertion, the arrangement angle of the reinforcing fibers in the outermost layer is ±
If it is set to 30 ° or less, it becomes easier. The thermosetting resin forms the matrix of the FRP inner cylinder, and epoxy resin, phenol resin, polyimide resin, unsaturated polyester resin or the like can be used.

ので好ましい。A recess is formed on the inner surface of the outer cylinder. As shown in FIG. 2, this recess may be a groove 4 formed at appropriate intervals and extending in the circumferential direction of the outer cylinder 3,
As shown in FIG. 3, it is also possible to form a groove 5 extending spirally in the cylinder axis direction of the outer cylinder 3. Further, as shown in FIG. 4, the groove 6 may be obtained by reducing the outer cylinder 3 itself at a desired pitch by electromagnetic machining or the like. However, when using such an outer cylinder, it is necessary to remove the convex portion formed on the outer surface by grinding or the like and finish the surface smooth.
However, after inserting the wound body 2 shown in FIG. 1 into an outer cylinder not subjected to such a diameter reduction process, the outer cylinder is subjected to a diameter reduction process, and as a result, an outer cylinder as shown in FIG. 4 is used. You can also create the same state as. In this case as well, finishing of the outer surface is required later. The depth of the groove may be about 0.1 to 0.5 mm, depending on the application. In the present invention, the reinforced fiber winding body 2 impregnated with the uncured thermosetting resin is inserted into the outer cylinder together with the mandrel before the thermosetting resin is cured. This insertion can be easily done because the thermosetting resin is not cured, and the thermosetting resin enters the recess of the outer cylinder along with the insertion so that the recess is filled with the thermosetting resin. Become. After the insertion, the thermosetting resin is heated and cured to form the inner cylinder, and the mandrel 1
Pull out. Then, as shown in FIG. 5, a composite cylinder of the FRP inner cylinder 7 and the metal outer cylinder 3 that is externally mounted on the inner cylinder 7 is obtained. The one shown in FIG. 5 uses the outer cylinder shown in FIG. Note that it is preferable to use an outer cylinder having an inner diameter slightly smaller than the outer diameter of the wound body 2 because the thermosetting resin can more reliably enter the concave portion of the outer cylinder due to insertion.

In this case, in particular, in order to improve the wear resistance of the surface, it is preferable to coat the outer surface of the outer cylinder with a plating film such as hard chrome plating or a ceramic spray coating.

ることができる。When the outer cylinder and the inner cylinder are combined so that the coefficient of linear thermal expansion of the outer cylinder in the circumferential direction is equal to or larger than that of the inner cylinder, the thermosetting resin is heated, cured and cooled. It is preferable since the adhesion between the outer cylinder and the inner cylinder will be further improved later. Such a combination can be achieved by selecting the arranging direction of the reinforcing fibers in the inner cylinder or selecting the type of metal forming the outer cylinder.
