る。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for molding a cylindrical body using a resin suitable for the purpose of use as the outer layer member and a fiber-reinforced thermosetting resin for the inner layer, and a roller using the cylindrical body. It is related to.
繊維強化熱硬化性樹脂（以下ＦＩＬＰと呼ぶ）ばガラス
）が露出しており、使用していると繊維を残して樹脂の
み摩耗してしまい、繊維ばかシ表面に残る場合が多い。The fiber-reinforced thermosetting resin (hereinafter referred to as FILP) is exposed, and when used, only the resin is worn away, leaving behind the fibers, which often remain on the surface of the fibers.
そのためローラー・の寸法精度、外周面のあらさ、その
老化の早さ、及びその対策として外周面再加工の必要性
が生じ、経済性及び安定性等好ましくない事が多い。Therefore, the dimensional accuracy of the roller, the roughness of the outer circumferential surface, the speed of its aging, and the need to rework the outer circumferential surface as a countermeasure against these problems arise, which are often unfavorable in terms of economy and stability.

欠点があり充分でなかった。Furthermore, in view of the strength and heat resistance of the roller, F-P is suitable as a structural material, but from the physical and chemical perspective of the surface, the physical properties of other resins may be appropriate. In these cases, methods have been used in which other resins are later applied or pasted onto the outer peripheral surface of the roller-shaped cylindrical body, but when applied or pasted, there are differences in thickness, strength, etc. It had its flaws and wasn't good enough.

る。The present invention, as a method to eliminate the above-mentioned drawbacks, selects the resin used for the outer layer member depending on the purpose, uses the conventional F-P for the inner layer, and connects both layers with reinforcing fibers used for the F-P. The object of the present invention is to obtain a method for forming a cylindrical body with a multi-layered structure, which is strengthened by the above-mentioned method and takes advantage of the physical and chemical properties of the outer layer member, and an excellent roller that employs a cylindrical body formed by this method.

の様な役目をする。The manufacturing method for the cylinder is as shown in the cross-sectional view of the mold in Figure 2. After assembling a centrifugal mold for cylindrical molding that can be divided into multiple parts, it is attached to a centrifugal molding machine and rotated, and resin 1 for the outer layer suitable for the purpose of use is applied. The resin is injected to a predetermined thickness, for example, about the virtual line 5 in FIG. After that, a thermosetting resin for FRP, such as an unsaturated polyester resin mixed with a curing agent, is injected and cured while continuing to rotate, and the specific gravity of the glass is higher than the specific gravity of resin 1 for the outer layer. Therefore, the centrifugal force increases, and as shown in Figure 1, the reinforcing fibers 3 penetrate into a part of the outer layer resin and harden, which is the key to joining the outer layer member 1 and the inner layer member 2.
It plays a similar role.

来る。Another method is to perform centrifugal molding using a mold with a groove corresponding to the lip in the case of a cylindrical body with a lip-like protrusion on the outer periphery as shown in Figure 3. In this case, before rotating, After placing the glass fiber continuous strand mat on the outside and the glass cloth inside the mold, the mold was rotated and flexible bisphenol-based unsaturated polyester resin was injected into the mold in an amount approximately twice the volume of the groove portion. - After the polyester resin is moved to the outer layer by centrifugal force and gelation begins, general bisphenol-based unsaturated polyester resin is injected. Mix. An ideal roller cylinder formed in this way is obtained, in which the lip portion is flexible and the cylinder body is rigid. The order of the resins injected into the mold is not fixed because it varies depending on the specific gravity of the resin and reinforcing fibers used, and it also needs to be changed depending on the selection and shape of the resin and reinforcing fibers for the outer layer and the inner layer. The reinforcing fibers used include glass carbon ceramics, inorganic fibers including metal fibers, organic fibers including natural and synthetic fibers, and the form is not particularly limited, such as cloth, cotton, thread fiber, etc. The form is selected depending on the purpose, and it is fine as long as it has a higher specific gravity than the resin.The thermosetting resin is free as long as it can be used for centrifugal molding, and in general, unsaturated polyester resin and vinyl ester resin are used. , epoxy resin, furan resin, etc. are selected depending on the purpose of use. In this way, the inner layer F-P can be formed by using commonly used materials, reinforcing methods, etc. as they are or by partially changing them.

形する。Furthermore, the outer layer resin 1 may be made of a material mixed with rubber powder to increase friction, or a thermoplastic resin may be used to make it flexible in hot water. It can correspond to the intended use of the cylinder. When a thermoplastic resin is used, the resin is heated to a high temperature and molded to give it fluidity.
