本発明は軽量で、腰が強（強力の大ぎな炭素繊維強化ゲ
ラステック製釣竿用穂先に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a fishing rod tip made of carbon fiber-reinforced gelastec that is lightweight and strong.
一般に釣竿用穂先は繊維強化プラスチツク材からなり、
強化繊維として汎用的にはガラス繊維が用いられている
。Fishing rod tips are generally made of fiber-reinforced plastic material.
Glass fiber is commonly used as reinforcing fiber.
しかしながら、近年に至って特に鮎竿、ヘラ竿等では軽
量で、かつ魚信に敏感であり、さらに魚の取込みの際に
操作性の良い、所謂軽量、硬調子の竿への要求が高まっ
てきている。However, in recent years, there has been an increasing demand for so-called lightweight, hard-toned rods that are lightweight, sensitive to fish movements, and have good operability when catching fish, especially for sweetfish rods and spatula rods. .
かかる竿の設計に、ｒ６いては穂先の設計が重要となり
、材料の観点から、もはやガラス繊維強化グラスチック
材ではこれらの要求を満足出来ないことが明確になって
きた。In the design of such rods, the design of the tip of the r6 rod becomes important, and from the viewpoint of materials, it has become clear that glass fiber-reinforced plastic materials can no longer satisfy these requirements.
このような現状に鑑み、本発明者等は種々検討を重ねた
結果、穂先の強化繊維として特定の材料特性と体積含有
量の組合せを採用することによってのみ、軽量で硬調子
な釣竿を製造することが可能となることを見出したもの
である。In view of this current situation, the inventors of the present invention have conducted various studies and have found that a lightweight and rigid fishing rod can be manufactured only by adopting a combination of specific material properties and volume content as the reinforcing fiber for the tip. We have discovered that this is possible.
本発明の要旨とするところは、弾性率が２５Ｘ １０３
ｋｆ１ｍＴＬ”以上、破断伸度が１％以上の炭素繊維か

範囲にある炭素繊維強化プラスチツク製釣竿用穂先にあ
る。The gist of the present invention is that the elastic modulus is 25X 103
The tip of a fishing rod is made of carbon fiber-reinforced plastic, which is made of carbon fiber having a diameter of 1 mTL" or more and a breaking elongation of 1% or more, and the volume content of the carbon fiber is in the range of 50 to 75%.

しく使用される。Matrix resins used in carrying out the present invention include thermosetting resins such as epoxy resins, unsaturated polyester resins, vinyl ester resins, polyimide resins, and phenolic resins, as well as nylon and polycarbonate in order to achieve the purpose of reducing moldability and weight. Thermo-n'' plastic resins such as are preferably used.
本発明で用いる炭素繊維の弾性率が２５Ｘ１０’ｋＰ／
朋２未満では本発明が目的とする硬調子の竿を得ること
ができない。The elastic modulus of the carbon fiber used in the present invention is 25X10'kP/
If it is less than 2, it will not be possible to obtain a rod with the hard tone that is the object of the present invention.
又伸度が１％より小さい炭素繊維では耐荷重能力が不足
して穂先が折れ易くなる。Furthermore, carbon fibers with an elongation of less than 1% lack load-bearing capacity and tend to break at the tip.
炭素繊維の体積含有率が５０係未満では高い弾性率が得
られず、又７５％を越すと炭素繊維同志の糸ずれが生じ
て強度が出なくなる。If the volume content of carbon fibers is less than 50%, a high elastic modulus cannot be obtained, and if it exceeds 75%, thread displacement occurs between the carbon fibers, resulting in no strength.
以上詳記した通り、本発明は、特定した条件を採用する
ことによってはじめて、本発明の目的を達成することが
出来るのである。As detailed above, the purpose of the present invention can only be achieved by adopting the specified conditions.
以下本発明を具体的に実施例に基づいて説明する。The present invention will be specifically described below based on examples.

得た。Example 1 Carbon fiber has an elastic modulus of 30 x 10' kl/rnn2,
Fibers with a strength of 350 kf/mn' were used, and vinyl ester was used as the resin. This material was subjected to pultrusion molding at a fiber volume content of 60% and heating conditions of 150° for 2 minutes to obtain a solid rond. This was cut to a fixed length and then processed into a centerless tapered shape to obtain the desired tip.

もつに至った。The tip of the present invention has a reinforcing fiber with an elastic modulus of 30 x 10"kl
/rnm, ', Since carbon fiber with an elongation of 1.2% and a fiber volume content of 60% are used, the elasticity is almost the same as that of a tip with a fiber volume content of 50 using conventional high-elasticity grade carbon fiber. The elongation at break of conventional high-elasticity products is as low as 0.6% (1.2%, which is about double the elongation of conventional products with high elasticity). Because we were able to achieve an elongation of
