2. Description of the Related Art In recent years, many fishing rods made of carbon fiber reinforced composite resin using carbon fibers as reinforcing fibers have been widely used because of their light weight and high mechanical strength. Has achieved great results.

Although such a conventional fishing rod is composed of a plurality of carbon fiber reinforced composite resin layers and the like, as shown in FIG. 3, a predetermined number of carbon fiber reinforced prepregs 101 cut into a predetermined shape and size are cut. It is formed by wrapping around the mandrel 100 and curing. At this time, since the fishing rod generally has a bending action, as the carbon fiber reinforced prepreg, as shown in FIG. 3, carbon fibers are arranged parallel to the axis of the fishing rod (θ = 0 °). A unidirectional prepreg 101 (straight layer 101 ') is used, but in order to improve the strength against crushing, the unidirectional prepreg 101 shown in FIG.
As shown in (a), (b) and FIG. 5, a cloth prepreg 10 in which a carbon fiber cloth (woven fabric) is used as a reinforcing fiber.
2a (cloth layer 102a ') or 90 ° prepreg 102b (90 ° layer 102b') in which carbon fibers are arranged in a 90 ° direction with respect to the axis of the fishing rod may be further used.

In this case, basically, as shown in FIG. 5, the unidirectional prepreg 101 is formed on the inner layer of the fishing rod.
(Straight layer 101 ') is often used.

However, in order to further prevent breakage and improve vibration damping characteristics, it is desired to improve tensile strength, compressive strength and elastic modulus, and further mechanical characteristics such as tenacity and impact resistance. However, there is a demand for further improvement in terms of feel during use, and in terms of moldability and fashionability (designability).

[0006]

In order to meet such demands, the present inventors have made a fiber-reinforced prepreg having one or more kinds of metal fibers such as titanium fibers, stainless fibers, and tungsten fibers as reinforcing fibers, Alternatively, at least the fiber-reinforced resin layer is a fiber-reinforced prepreg layer formed by a fiber-reinforced prepreg having one or more kinds of metal fibers as reinforcing fibers and dissimilar fibers such as carbon fibers other than metal fibers. In the meantime, it has been proposed to provide one layer or a plurality of layers on the outermost layer or the innermost layer.

Such a fiber reinforced prepreg containing at least metal fibers is excellent in compressive strength, impact strength and torsional fracture strength, and when a fishing rod is manufactured with these prepregs, it is made of fiber reinforced composite resin. Despite the fact that it is a fishing rod, it has been found that it has high elasticity, excellent vibration transmission, and good sensitivity (usability).

However, it is desired to further improve the torsional fracture strength, the impact resistance, and the feel of the fishing rod manufactured by using the fiber reinforced prepreg.

The inventors of the present invention have conducted many research and experiments to improve a fiber reinforced prepreg having at least a metal fiber as the reinforcing fiber, and as a result, the surface of the metal fiber as the reinforcing fiber is treated with phosphate. Or by chromate treatment, the metal fibers themselves are reinforced, and the adhesion between the metal fibers and the matrix resin is significantly improved, and the torsional fracture strength and impact resistance of the fishing rod manufactured using these fiber reinforced prepregs. It was also found that the feel during use can be greatly improved.

The present invention has been made based on such a new finding.

Therefore, it is an object of the present invention to provide a fishing rod which has a significantly improved mechanical strength such as torsional fracture strength and impact resistance, and a feeling in use, and which is aesthetically excellent. is there.

[0012]

The above object can be achieved by a fishing rod according to the present invention. In summary, the present invention, in a fishing rod consisting of a plurality of fiber reinforced resin layer, as a reinforcing fiber, a fiber reinforced prepreg layer having at least metal fibers subjected to phosphate treatment or chromate treatment on the surface,
The fishing rod is characterized in that one layer or a plurality of layers are provided in the outermost layer or the innermost layer at least between the fiber reinforced resin layers. Preferably, on the surface of the metal fibers, a metal salt coating film having a coating amount of 0.2 to 10 g / m ² is formed by the phosphate treatment, and a coating amount of 0.01 to 10 g by the chromate treatment.
A metal salt coating of 0.15 g / m ² is formed.

FIG. 6 is a sectional view showing an embodiment of the fiber reinforced prepreg which is a feature of the present invention. In this embodiment, the fiber reinforced prepreg 1 is configured to have reinforcing fibers impregnated with the matrix resin 2. According to the present invention, as the reinforcing fiber, one or more kinds of metal fibers 4 selected from titanium fiber, amorphous fiber, steel fiber, stainless fiber, tungsten fiber, aluminum fiber and the like are used.
Is used. The metal fiber 4 may have various fiber diameters, such as a small diameter of 5 to 30 μm or a large diameter of 50 to 150 μm.

In the fiber-reinforced prepreg 1 of the present invention, as shown in FIG. 7, the reinforcing fiber is selected from the above-mentioned titanium fiber, amorphous fiber, steel fiber, stainless fiber, tungsten fiber, aluminum fiber and the like. In addition to the one or more kinds of metal fibers 4, it is possible to have different kinds of fibers 6 different from these metal fibers 4. The different fibers 6 are selected from inorganic fibers such as carbon fibers, boron fibers, glass fibers, alumina fibers, silicon carbide fibers and silicon nitride fibers, and organic fibers such as aramid fibers, polyarylate fibers and polyethylene fibers.
Seed or multiple species. The heterogeneous fiber 6 also has a small diameter of 5 to 30 μm, or 50 to 150, like the metal fiber 4.
Various fiber diameters can be used, such as those with large diameters of μm.

As the matrix resin 2, a thermosetting matrix resin such as epoxy resin, unsaturated polyester resin, polyurethane resin, diallyl phthalate resin or phenol resin can be used. Further, a curing agent and other imparting agents such as flexibility imparting agent are appropriately added so that the curing temperature is 50 to 200 ° C.

As a preferred example, an epoxy resin is preferable as the matrix resin, and usable epoxy resins include, for example, (1) glycidyl ether type epoxy resins (bisphenol A, F, S type epoxy resin, novolac type epoxy resin). Resin, brominated bisphenol A epoxy resin); (2) cycloaliphatic epoxy resin;
(3) Glycidyl ester-based epoxy resin; (4) Glycidylamine-based epoxy resin; (5) Heterocyclic epoxy resin; and one or more kinds selected from other various epoxy resins, particularly bisphenol A, F, S
Glycidyl amine epoxy resin is preferably used.
As the curing agent, amine curing agents such as dicyandiamide (DICY), diaminodiphenylsulfone (DDS), diaminodiphenylmethane (DDM); acid anhydrides such as hexahydrophthalic anhydride (HHP)
A), methylhexahydrophthalic anhydride (MHHPA)
Etc. are used, but amine-based curing agents are particularly preferably used.

The mixing ratio of the reinforcing fiber and the matrix resin 2 in the fiber reinforced prepreg 1 can be adjusted as desired.
Generally, weight% of reinforcing fiber: matrix resin = 30-8
The range of 0:20 to 70 is good, and preferably 40 to 75:
25-60. Also, the thickness T of the fiber reinforced prepreg 1
Is usually 20 to 300 μm.

According to the present invention, the metal fibers 4 used in the fiber reinforced prepreg 1 are previously subjected to a phosphate treatment or a chromate treatment as a chemical conversion treatment.

When the present inventors manufacture a fishing rod using the fiber-reinforced prepreg 1 using the metal fibers 4,
Fiber reinforced prepreg 1 by using metal fibers 4
In order to fully exert the effect of improving the mechanical strength of, and to obtain a fishing rod having a significantly improved mechanical strength such as torsional fracture strength and impact resistance, and a feel at the time of use, repeated studies were conducted.

As a result, in the conventional fiber reinforced prepreg 1, the adhesiveness between the metal fiber 4 and the matrix resin 2 is low, and therefore the mechanical strength of the fiber reinforced prepreg 1 due to the use of the metal fiber 4 as the reinforcing fiber. The fishing rod obtained by using this fiber-reinforced prepreg 1 does not sufficiently exert the strength improving effect, and the mechanical strength improving effects such as torsional fracture strength and impact resistance are not sufficiently imparted, and the fishing rod is torsionally fractured. It was found that the strength and impact resistance were not sufficiently improved, and the feeling during use was not sufficiently improved.

The present inventors have found that in order to improve the adhesiveness of the metal fiber 4 with the matrix resin 2, it is extremely effective to subject the metal fiber 4 to a phosphate treatment or a chromate treatment in advance.

By subjecting the metal fiber 4 to a phosphate treatment or a chromate treatment in advance, a metal salt coating is formed on the surface of the metal fiber, and this metal salt coating enhances the adhesiveness of the metal fiber 4 with the matrix resin 2. Thereby, the effect of improving the mechanical strength such as the torsional fracture strength and the impact resistance of the fishing rod manufactured by the fiber reinforced prepreg 1 using the metal fiber 4 can be sufficiently exerted, and the feeling during use is also improved. I found that it could be improved.

As the phosphate treatment, either zinc phosphate-based or manganese phosphate-based phosphate treatment can be used. In particular, when the metal fibers 4 are steel fibers or stainless fibers, iron phosphate-based phosphate treatment can be used in addition to the zinc phosphate-based or manganese phosphate-based treatment described above.

The treatment conditions such as the liquid composition of the phosphate treatment, pH, treatment temperature, treatment time and the like can be ordinary conditions, but from the viewpoint of improving the adhesion of the metal fibers 4 to the matrix resin 2. Therefore, it may be appropriately determined according to the type of the metal fiber 4 to be used.

Specifically, the phosphate treatment is performed by using the metal fiber 4
It is preferable to perform so that a metal salt coating film having a coating amount of 0.2 to 10 g / m ² is formed on the surface. When the amount of the metal salt coating is less than 0.2 g / m ² , the modifying effect that contributes to the improvement of the adhesiveness due to the formation of the metal salt coating on the surface of the metal fiber 4 is not sufficient, and the matrix resin of the metal fiber 4 is insufficient. The adhesive strength with 2 does not increase. Conversely, the amount of metal salt coating is 1
If it exceeds 0 g / m ² , the metal salt coating becomes too thick, which causes the adhesive strength of the metal fiber 4 with the matrix resin 2 to decrease. Therefore, the amount of the metal salt film formed by the phosphate treatment is 0.2 to 10 g / m ² , preferably 0.
A range of 5 to 3.0 g / m ² is preferable.

An example of zinc phosphate treatment is Palpond L-3080 manufactured by Nippon Parker Rising Co., Ltd.
There is the use of the zinc phosphate processing system. If the metal fiber 4 is a stainless fiber, the conditions for the zinc phosphate treatment are as follows.

Total acidity 23 points Free acidity 0.9 points Accelerator concentration 3 points Temperature 45 ° C Immersion time 2 minutes

As the chromate treatment, a chromate treatment used for the surface treatment of a steel plate or the like can be used for almost all of the metal fibers 4, regardless of the type. Similarly,
The treatment conditions such as the liquid composition of the chromate treatment, the pH, the treatment temperature, the treatment time and the like can be performed under normal conditions, but the metal fibers used for the purpose of improving the adhesion of the metal fibers 4 to the matrix resin 2. It may be appropriately determined in consideration of the four types and the like.

Specifically, in the chromate treatment, the coating amount on the surface of the metal fiber 4 is 0.
It is preferable to carry out so that a metal salt coating (chromate coating) of 01 to 0.15 g / m ² is formed.

As an example of the chromate treatment, Zinchrome R-1415A manufactured by Nippon Parker Rising Co., Ltd.
There is a chromate treatment using. If the metal fiber 4 is a stainless fiber, the chromate treatment is as follows.

That is, the concentration of zinc chromium R-1415A is 1
1 point of treatment liquid was prepared, and the degreased and dried stainless fiber was coated with a roll coater at room temperature at a coating amount of 5 g /
The coating is m ^2, dried further coated stainless fibers 80 ° C. dryer to remove moisture.

The above-mentioned phosphate treatment and the like can be carried out by immersing the metal fiber 4 in a treatment liquid, but prior to the phosphate treatment and the like, the surface of the metal fiber 4 is degreased and washed with water, and phosphoric acid is used. The reason why it is necessary to wash and dry the metal fibers 4 immediately after the salt treatment and the like is the same as in the case of the phosphate treatment and the like for ordinary steel plates and the like.

In the fiber-reinforced prepreg 1 of the present invention, the reinforcing fibers can be constituted by arranging the metal fibers 4 or the metal fibers 4 and the dissimilar fibers 6 in one direction. ) It is also possible to use in the state.

In Table 1, various fiber-reinforced prepregs having at least metal fibers 4 as reinforcing fibers and arranged by arranging the reinforcing fibers in one direction, and fishing rods prepared by using these fiber-reinforced prepregs The evaluation of the fishing rod of is shown.

The metal fibers 4 are stainless fibers having a fiber diameter of 20 μm, titanium fibers having a fiber diameter of 20 μm, and fiber diameters of 20 μm.
The aluminum fiber of m was used, which was previously subjected to chemical conversion treatment. The phosphate treatment was performed using PALPON L-3080 manufactured by Nippon Parker Rising Co., Ltd., and the chromate treatment was performed using Zinchrome R-1415A manufactured by Nippon Parker Rising Co., Ltd.

As the different fiber 6, a PAN-based carbon fiber having a fiber diameter of 7.0 μm (trade name: T300, manufactured by Toray Industries, Inc.) is used as the carbon fiber, and the glass fiber has a fiber diameter of 13 μm.
Glass fiber (made by Asahi Fiber Glass Co., Ltd., standard name E glass), aramid fiber made of aramid fiber having a fiber diameter of 12 μm (made by Teijin Ltd., trade name Technora), and polyarylate fiber made of poly having a fiber diameter of 23 μm. Arilate fiber (trade name Vectran manufactured by Kuraray Co., Ltd.) was used.

An epoxy resin was used as the matrix resin 2 in each fiber-reinforced prepreg.

[0046]

[Table 1]

As shown in Table 1, when the fiber-reinforced prepreg of the present invention was used (Examples 1 to 8), the metal fiber 4 was treated with zinc phosphate or chromate, and therefore the matrix resin was used. The adhesiveness with 2 is good, and the performance of the fiber reinforced prepreg is sufficiently exhibited by using the metal fiber 4. As a result, the obtained fishing rod has improved torsional fracture strength and impact resistance, and both are excellent or better. Improved,
In addition, the feeling of use of the fishing rod was more than good. On the other hand, in Comparative Examples 1 to 3, the metal fibers 4 were not subjected to the phosphate treatment or the chromate treatment, or even if the metal fiber 4 was subjected to the phosphate treatment, the coating amount was small and was not effectively performed. The adhesion of the fiber 4 to the matrix resin 2 was low, and the fishing rod obtained for that reason was inferior in at least either torsional fracture strength or impact resistance.

[0048]

As described above, the fiber reinforced prepreg forming the fiber reinforced prepreg layer of the fishing rod of the present invention has at least one or more kinds of metal fibers as reinforcing fibers, and the surface of the metal fibers is Since it is subjected to phosphate treatment or chromate treatment, the adhesiveness of the metal fiber to the matrix resin is high, and it is possible to sufficiently exert the effect of improving the mechanical strength by using the metal fiber as the reinforcing fiber. In particular, the mechanical strength such as torsional fracture strength and impact resistance is significantly improved, and the feel during use is significantly improved.
