Description

  The present invention relates to a tubular body and a method for manufacturing the same, and more particularly to a member for fishing / sports equipment including fishing equipment, golf equipment, ski equipment, tennis equipment, and a method for manufacturing the same.

  Sporting equipment such as fishing equipment, golf equipment, ski equipment, tennis equipment, and the like tend to improve their functions and characteristics and reduce weight while maintaining their strength.

  On the other hand, in order to appeal to the user's hobbies, various decorations are applied to the fishing equipment and sports equipment. For this reason, various coatings and the like are applied to these members so as to show an excellent appearance. In recent years, with the weight reduction of fishing equipment and sports equipment, the ratio of the coating layer in the member weight has increased. Specifically, in fishing rods, the weight of the coating layer in the rod tube weight has risen to an extent that occupies 5 to 10% or more. For this reason, the paint layer and the decorative layer are a major cause of hindering the weight reduction of the fishing equipment and sports equipment described above.

  As a conventional technique for reducing weight and improving strength, there is one disclosed in Patent Document 1. This is a technique related to a fishing rod in which a portion where a resin is exposed and a portion where a continuous reinforcing fiber is exposed are formed on the surface of a rod tube in which a fiber reinforced synthetic resin prepreg obtained by impregnating a reinforcing resin with a synthetic resin is wound. . In this way, the weight of the member can be reduced and the strength can be improved.

  For example, as shown in FIG. 8, it is configured by providing a circumferential fiber layer 44 on an axial length direction fiber layer 43, and each fiber layer 43, 44 is formed by impregnating a reinforcing fiber 45 with a resin 46. Then, the outer surface is a rough surface, and light is irregularly reflected. For this reason, the appearance is poor and a thick coating is required.

Also, as shown in FIG. 9, when the surface is polished with a sander belt or the like, the soft resin 46 portion is greatly scraped to form the concave portion 47 and the hard reinforcing fiber 45 becomes the convex portion 48. The surface is rough. Thus, even if the surface is polished, an excellent appearance cannot be obtained.

  Therefore, it has been difficult with conventional techniques to achieve both weight reduction / strength improvement and appearance improvement. This invention is made | formed in view of this point, and it aims at providing the tubular body which is lightweight and has the outstanding external appearance.

  As a result of intensive research on members for fishing / sports equipment having an outer surface in which a base material and a reinforcing material are mixed, the present inventors have reduced the weight by forming the outer surface in a mirror-like shape. In addition, the present inventors have found that the decorativeness is improved and have made the present invention.

That is, according to the present invention (Claim 1), a surface layer of a member body including a base material made of a synthetic resin and reinforcing fibers is a circumferential fiber layer formed by winding a fiber reinforced prepreg, and the base of the surface layer is formed. Providing a tubular body for fishing / sports goods, characterized in that the outer surface where the material and reinforcing fibers are mixed is formed into a mirror-like surface with the circumferential fibers exposed by chemical buffing. To do.

Further, in the present invention (Claim 2), in the tubular body (Claim 1), the outer surface where the base material and the reinforcing fiber are mixed is a tape mark generated when tightening and thermoforming with a tightening tape. Provided is a tubular body for fishing / sports goods having an uneven shape, wherein a synthetic resin and a reinforcing fiber are formed in a flush mirror shape while maintaining the uneven shape.

The present invention (Claim 3) is a tubular body for fishing / sports goods characterized in that in the tubular body (Claim 1 or 2), the volume ratio of the reinforcing fiber portion in the surface layer is 55% or more. Provide the body .

The present invention (Claim 4) is characterized in that, in the tubular body (Claims 1 to 3), the ratio of the reinforcing fiber portion when viewed from the outer surface of the surface layer is 70% or more. A tubular body for fishing and sporting goods is provided.
Further, according to the present invention (Claim 5), in the above tubular body (Claims 1 to 4), an axial length direction fiber layer is provided below a surface layer as a circumferential direction fiber layer, and fishing / sports A tubular article is provided.
The present invention (Claim 6) is characterized in that in the tubular body (Claims 1 to 5), a thin film of 10 μm or less is formed on the outer surface of the member body formed in a mirror surface. A tubular body for sports equipment is provided.
In another aspect of the present invention, a member body including a base material and a reinforcing material, an outer surface where the base material and the reinforcing material are mixed, or a hard part of a member body including a hard portion and a soft portion, Provided is a method for manufacturing a tubular body, characterized in that an outer surface mixed with a soft portion is polished by contact with an elastic polishing member by a chemical polishing method to form a flush surface.
Still another aspect of the present invention is that a member body including a synthetic resin and a reinforcing fiber is mixed with a synthetic resin and a reinforcing fiber, and the outer surface having a concave and convex shape is maintained in a concave and convex shape by a chemical buffing method. However, the manufacturing method of the tubular body characterized by forming a synthetic resin and a reinforced fiber in the same mirror surface shape is provided.

  In the present invention, the “mirror surface” is not limited to a surface such as a mirror or a lens that reflects light in a specific direction, but is not necessarily limited to such a surface. Meaning word.

  The surface roughness of the mirror-shaped surface is preferably 1 μm or less, and more preferably 0.5 μm or less. In order to obtain a cleaner mirror surface, the thickness is most preferably 0.2 μm or less.

  The surface roughness is measured by a measuring method specified in JISB0601. When the peaks and valleys on the surface are continuous, the measurement is performed by the 10-point average roughness Rz. Ry can also be used when the number of peaks and valleys on the surface is small and it is difficult to measure with Rz.

  The surface of the member for fishing / sporting goods of the present invention is arbitrary, and the tape is generated when a fiber reinforced prepreg impregnated with a synthetic resin is wound around the core, tightened with a tightening tape, and heat-molded. A more preferable appearance can be obtained by leaving a concavo-convex shape, which is a trace, or forming concavo-convex shapes or patterns by the outer shape of a mold or machining, and making these surfaces mirror-like.

  Further, in the present invention, “level” means that smoothness is maintained over both portions of the surface where materials or properties having different physical properties are mixed. For example, “to form a flat mirror surface” means that all parts are smooth without grinding only the high hardness part into a crest or only the low hardness part into a valley. Means.

  In the present invention, the mirror-like surface can be formed by polishing by a chemical polishing method, particularly a chemical buff (CB) polishing method. It is also possible to carry out by a combination of a sponge polishing method and a chemical buff polishing method.

  The chemical buff polishing method is a wet polishing method in which chemical polishing by a chemical action of a polishing aid and buff polishing utilizing physical polishing power are combined. In this chemical buffing method, as an elastic polishing member, an appropriate amount of abrasive impregnated with a nonwoven fabric such as felt or hemp, a woven fabric, or a soft foam is used. The appropriate amount here is preferably 10 to 100 cc / min in consideration of economy, workability, polishing power and the like.

  In the present invention, particularly excellent appearance can be obtained by applying a chemical buffing method to a fiber layer having a low resin content or a high fiber volume ratio. The volume ratio Vf of the fibers in the fiber layer that provides an excellent appearance by the chemical buffing method is 55% or more, preferably 60% or more, and more preferably 65 to 90%. The fiber volume ratio Vf ′ of the polished surface (when viewed from the surface) is 70% or more, preferably 80% or more, and more preferably 85% or more.

  Thus, by combining the fiber layer having a high fiber volume ratio and the chemical buffing method, an excellent appearance can be obtained with only the material without painting, and further weight reduction can be achieved. The effect that it is hard to be damaged is also acquired by not painting only with a raw material.

  The lower the resin content of the fiber layer subjected to the chemical buffing method, the better the glossy surface can be obtained, especially in the case of a fiber layer having a resin content of 30% by weight or less.

  In the chemical buff polishing method, polishing is performed while rotating the object to be polished and the elastic polishing member, and the number of rotations is 30 to 120 rotations / minute for the object to be polished and 350 rotations / minute for the wheel of the elastic polishing member. Degree.

  The polishing may be performed with the surface of the object to be polished roughened or may not be roughened. When roughening the surface of the object to be polished, first, rough polishing is performed with a non-woven fabric polishing material of about # 240 to # 800, and then polishing is performed with a non-woven fabric polishing material of about # 2000 to # 8000. Polishing by chemical buffing is preferable. Thus, a desired mirror-like surface can be efficiently obtained by polishing in a plurality of steps in which the polishing eyes are made finer step by step.

  The tubular body of the present invention includes a hard part and a soft part of a member body including a base material and a reinforcing material, an outer surface of the base material and the reinforcing material mixed together, or a hard part and a soft part. Since the outer surface in which is mixed is formed in the same mirror surface shape, it is lightweight while maintaining strength or hardness, and has an excellent appearance.

  In addition, by forming a thinner thin film on the surface formed in the same mirror surface, a more excellent appearance can be obtained while preventing an increase in weight. Furthermore, according to the method for manufacturing a member for fishing / sports goods of the present invention, by using a chemical polishing method, particularly a chemical buff polishing method, while maintaining strength or hardness, it is lightweight and has an excellent appearance. The member for fishing / sports goods which it has can be manufactured efficiently.

  Hereinafter, various embodiments of the present invention will be described more specifically with reference to the drawings.
