〈産業上の利用分野〉
本発明は、炭素繊維又はグラスファイバー等の繊維によ
って強化された部材と通常の熱可塑性合成樹脂即ち合成
樹脂とを一体的に結合する方法に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for integrally bonding a member reinforced with fibers such as carbon fibers or glass fibers to an ordinary thermoplastic synthetic resin, that is, a synthetic resin. .
〈従来の技術〉
従来、炭素繊維やグラスファイバー等の繊維入り強化部
材は応用され初めて新しく、従って加工上の問題もあっ
て利用範囲が限られているのが現状である。<Prior Art> Conventionally, reinforcing members containing fibers such as carbon fibers and glass fibers have only been applied for the first time, and therefore, their range of use is currently limited due to problems in processing.
つまり、上記の繊維入り強化部材、殊に炭素繊維は管状
や、板状に、それ自体で形づくるような場きのみに限ら
れている。In other words, the above-mentioned fiber-filled reinforcing members, especially carbon fibers, are limited to applications where they can be formed into tubes or plates by themselves.
例えば最も広く利用されているものとしては第６図のよ
うに釣竿があり、釣竿については、竿杆１の部分とリー

維入り強化部材にて構成し、リール取付台座は通常の合
成樹脂にて別途成形されているので、両部材を結合する
手段として、その後竿杆とリール取付台座との間に接着
剤を介在させ、両者をテープや線条材２ａ等により緊縛
し、更にその上に適宜塗装を施して一体的に構成するも
のであった。For example, the most widely used item is a fishing rod as shown in Figure 6.The fishing rod consists of a rod 1 and a reel mounting base 2, and the rod is made of fiber reinforced material. The reel mounting pedestal is separately molded from ordinary synthetic resin, so as a means of joining both parts, adhesive is then interposed between the rod rod and the reel mounting pedestal, and both are attached with tape. It was constructed in one piece by binding it tightly with wire material 2a or the like, and then painting it as appropriate.

ンや螺鋲１１を通して連結していた。In addition, in the case of a bicycle body frame as shown in FIG. 7, at the joint between the separately processed head tube 8 and the iron tube body 4.5, the tips of the tube bodies 4 and 5 are connected to the head tube 8.
The fittings were fitted into the connecting parts 6 and 7 of the fitting parts, and were connected to each other by passing a bottle or screw 11 between the fitting parts.
〈発明が解決しようとする課題〉
しかし、上記のように繊維入り強化部材を一次製品とし
たものでは、これを他の部品と結合したり、組立たりす
る二次加工が極めて困難である。<Problems to be Solved by the Invention> However, when the fiber-filled reinforcing member is used as a primary product as described above, secondary processing such as joining or assembling it with other parts is extremely difficult.
即ち繊維入り強化部材で前者釣竿を構成する場合、強度
は頗る高いが、加工性が悪く、例えば孔をあけた場合は
忽ち孔の部分からクラックを生じ、不測の事態を招来す
る恐れがあり、従って螺子止めなどによって２つの部材
を結合することはできず、常に接着剤や、テープその他
線条材などによって締め付は一体的に構成することに限
られていた為に組立手数が多くなり生産性を高めること
ができなかった。That is, when the former fishing rod is constructed from a reinforced fiber-filled member, the strength is extremely high, but the workability is poor, and for example, if a hole is drilled, a crack may immediately occur from the hole, which may lead to an unexpected situation. Therefore, it is not possible to connect two parts with screws, etc., and tightening has always been limited to integral construction using adhesives, tapes, or other wire materials, which increases the number of assembly steps and production. I couldn't improve my sexuality.
又、後者の自転車の車体枠を組付ける例では、嵌合によ
る組立である以上、精度をいくら高めても嵌合交差の関
係上、長期間使用していると遊び間隙が次第に拡大し、
しかもそれは加速度的となり、使用不能となる欠点があ
った。In addition, in the latter example of assembling a bicycle body frame, since the assembly is done by fitting, no matter how much precision is improved, due to fitting overlap, the play gap will gradually expand over long periods of use.
Moreover, it has the disadvantage that it accelerates and becomes unusable.
そこで本発明は、上記従来例の欠点を解決し、繊維入り
強化部材と合成樹脂の確実な結合方法を提供しようとす
るものである。SUMMARY OF THE INVENTION Therefore, the present invention aims to solve the above-mentioned drawbacks of the conventional examples and provide a method for reliably bonding a fiber-filled reinforcing member and a synthetic resin.

炭素繊維又はグラスファイバー等の繊維によって強化さ
れた強化部材を成形金型の保持部内に静置し、該強化部
材の周囲に形成されたキャビティ内に熱可塑性合成樹脂
を注入することにより二部材を一体的に結合する。Means for Solving the Problems〉 A reinforcing member reinforced with fibers such as carbon fiber or glass fiber is placed in a holding part of a mold, and a thermoplastic composite is placed in a cavity formed around the reinforcing member. The two parts are integrally joined by injecting resin.
〈作用〉

脂は放熱によって収縮して強力に強化部材へ密着し安定
する。<Operation> The fiber-filled reinforcing member is placed in a molding die, thermoplastic synthetic resin is injected into the surrounding cavity to integrate it, and then released from the molding die to form a thermoplastic synthetic resin. The resin contracts due to heat radiation and strongly adheres to the reinforcing member, making it stable.
〈実施例〉
以下本発明について、図面に示す実施例により詳細に説

取付台座２をインサート成形する。<Example> The present invention will be described in detail below using examples shown in the drawings. First, FIGS. 1 and 2 relate to a fishing rod;
Core material 1 in glass fiber or carbon fiber rod 1
', the rod rod 1 is inserted into the holding part of the mold 3, and a thermoplastic synthetic resin is injected into a molding cavity 2' of a predetermined shape formed around the rod rod 1, thereby forming a reel mounting base. 2 is insert molded.
その後、竿杆１を金型３から取り出すと共に芯材１′を
摘除すると、竿杆の周囲にインサート成形した合成樹脂

, 3' are inserted and held in the glass fiber or carbon fiber tubes 4, 5 with reinforcing core materials 9, 9 fitted in their ends in advance, and at the same time, the joining portions of both tubes 4, 5 are held. The slide core 10 formed by inserting the slide core 10 into the mold 3.3'', and each formed between the inner end outer periphery of the tube body 4.5 and the mold 3.3'' By injecting molten thermoplastic synthetic resin into the cavities 6'' and 78'' at high pressure, a head is attached to one end of the glass fiber tubes 4 and 5 via the connecting parts 6 and 7, as shown in FIG. The tube 8 can be integrally insert molded.
上述のようにして繊維入り強化部材と熱可塑性合成樹脂
つまり通常の合成樹脂とを該強化部材の強度を全く損ね

〈発明の効果〉
本発明は上述のようになり、繊維入り強化部材と合成樹
脂との結合に接着剤や、ビス止め用の孔を全く設けるこ
となく互いに一体的に結合できる。<Effects of the Invention> The present invention is as described above, and the fiber-filled reinforcing member and the synthetic resin can be integrally bonded to each other without using any adhesive or providing holes for screwing.
その結果、強化部材に切り込みや、孔明は等の加工を施
さないから強度低下を来さない。As a result, since the reinforcing member is not subjected to any processing such as cuts or holes, there is no reduction in strength.
又、強化部材を囲んで合成樹脂を設けているので冷却と
同時に収縮して一層両者は強固に密着結合して遊隙を生
じない、そして長期に亘り十分な強度を保つことができ
る。In addition, since the synthetic resin is provided surrounding the reinforcing member, it shrinks as it cools, and the two are more tightly bonded together without any play, and sufficient strength can be maintained over a long period of time.
更に強化部材と結合する合成樹脂は熱可塑性合成樹脂で
あるから選択幅が広いなどの優れた効果を有する。Furthermore, since the synthetic resin bonded to the reinforcing member is a thermoplastic synthetic resin, it has excellent effects such as a wide selection range.
