［ａ業上の利用分野］
本発明は、ケーブル状複合材料及びその製造方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Application in Industry] The present invention relates to a cable-like composite material and a method for manufacturing the same.
［従来の技術］
ケーブル状の複合材料は、その使用環境や負荷に応じて
複数のケーブルを束ねて用いられる。その場合に、個々
のケーブルがばらけさせない為に、従来の鋼線ワイヤー
に見られる様に、撚り線にして個々のケーブルの位置関
係が乱れないようにしてやる必要がある。[Prior Art] Cable-shaped composite materials are used by bundling a plurality of cables depending on the usage environment and load. In this case, in order to prevent the individual cables from coming loose, it is necessary to strand the cables so that the positional relationship of the individual cables is not disturbed, as is the case with conventional steel wires.
母材としてプラスチックなどを用いた複合材料は、金属
のような大きな塑性変形を生じず、弾性変形のみが生じ
る。すなわち、剛直な複合材料にまで硬化が進んでしま
ってからでは金属線と同しような撚り線加工をしてもそ
の弾性変形に応じた大きな撚り戻し力の為に、撚り線に
はできない。Composite materials that use plastic or the like as a base material do not undergo large plastic deformations like metals, but only undergo elastic deformation. In other words, once the composite material has hardened into a rigid composite material, even if it is processed into a stranded wire in the same way as a metal wire, it cannot be made into a stranded wire because of the large untwisting force corresponding to its elastic deformation.
したがってケーブル状複合材料の撚り線を製造する場合
には、可撓性のあるケーブル状プリフォームという中間
製品の段階で撚り線加工を行う必要がある。Therefore, when producing stranded wires of cable-like composite material, it is necessary to perform stranding processing at the stage of an intermediate product called a flexible cable-like preform.
ケーブル状複合材料は第５図及び第６図のような工程で
製造される。まず、クリール５から巻きだした高強度も

プレグ１を作成する。The cable-shaped composite material is manufactured through the steps shown in FIGS. 5 and 6. First, reinforcing fibers 6 (carbon fibers, glass fibers, aramid fibers, SiC fibers, etc.) having high strength or high elastic modulus are unwound from a creel 5 and are created using a bundler 7 (or gold thread machine, twisting 12N). The resulting fiber bundle 8 is passed through an impregnating tank 9 to be impregnated with thermosetting resin A, and then excess resin is squeezed out using a wringer 10 to create a cable-like prepreg 1.

面層のみを固化させたケーブル状プリフォーム４を用い

システム１１を用いてケーブル状プリフォーム４の作成
を行なう。Since the surface of this cable-like prepreg 1 is uncured and soft, the resin inside oozes out when it is subjected to twisting or handling operations. In order to prevent this bleeding, it is necessary to use a cable preform 4 in which only the surface layer of the cable prepreg 1 is solidified before the wire stranding process. A shaped preform 4 is created.

料１５とする。A plurality of cable-shaped preforms 4 are combined and twisted using a strand processing machine 12 to form strands 13. After the molding, the cable-shaped preform 4 is further heated in a curing/heating device 14 such as a heating furnace or a hot water tank to completely cure the cable-shaped preform 4 into a cable-shaped composite material 15.

The cable tension required for the entire manufacturing equipment is determined by the pulling device 16.
It is given by. The line speed of the manufacturing device is also determined by the take-off device 16.
ケーブル状プリフォーム作成システム１１の方法につい
ては幾つかの提案がなされている。Several proposals have been made regarding the method of the cable-like preform manufacturing system 11.
それらは！ａ維束に含浸した樹脂を未硬化の状態で何ら

が生ずる。For example, a cable-like preform production system (Japanese Patent Application Laid-Open No. 57-25579) as shown in FIG. 7 has been proposed. This method is as follows. First, a cable-like prepreg 1 impregnated with a thermosetting resin is coated with a heated and melted thermoplastic resin B using a melt extruder 17 and a crosshead 18, and then passed through a cooling water tank 19 for rapid cooling to harden the thermoplastic resin B. A cable-shaped preform 4b is produced. However, with this method, a soft thermoplastic resin such as polyethylene is used as the coating, so there is no problem in terms of flexibility, but the coated thermoplastic resin is susceptible to abrasion during stranding and handling. There is a problem that the surface is easily torn. If an attempt is made to thicken the coating to a certain extent, a problem arises in that the weight per unit length of the product increases and the @1 property, which is one of the advantages of cable-like composite materials, is lost.
そこで第８図のようなケーブル状プリフォーム作成シス
テム（特開昭６２−１８６７９号）も提案されている。Therefore, a cable-like preform production system (Japanese Patent Application Laid-open No. 18679/1983) as shown in FIG. 8 has been proposed.

じ込めケーブル状プリフォーム４ｃを作成している。According to this, a cable-shaped prepreg 1 impregnated with thermosetting resin A is passed through a dry powder agent tank 20, and a dry powder 21 is sprinkled on the surface and solidified by drying. Alternatively, the thermosetting resin A is sealed by coating with fibers 23 having high strength and low elongation, thereby creating a cable-like preform 4c.
［発明が解決しようとする課題］

ち、低速度でしか稼働できない編組機に律速され、製造
速度は著しく低下させられ、生産性が低いという課題で
ある。[Problems to be solved by the invention] However, there are two problems even with the above method. The first problem is that it is quite difficult to completely dry the uncured resin surface even with dry powder, and depending on how the resin is handled after being sprinkled with powder, the resin may leak out from the gaps between the braided threads. If the resin leaks partially, the amount of resin impregnated in that part will be less than in other parts, and the load transferred by the resin to the reinforcing fibers will not be uniform, resulting in stress concentration and a decrease in the strength of the cable. The second challenge is the use of a braiding machine, which is a very slow device. In other words, the production speed is significantly reduced due to a braiding machine that can only operate at low speeds, resulting in low productivity.

The VA fiber bundle 8 is passed through an impregnating tank 9 to be impregnated with a thermosetting resin A, and then the excess resin is squeezed out using a squeezing machine 10 to obtain a cable-like prepreg 1. In this device, the diameter of the cable-like prepreg 1 made of thermosetting resin can be freely selected from about 0.51 to 30 mm.

1, a flexible cable-like preform 4a is created. That is, on the surface of the cable-like prepreg 1 impregnated with an epoxy resin as the thermosetting resin A, the thermosetting resin A is added as the thermosetting resin C, which hardens more quickly under the same PA conditions than the thermosetting resin A. An epoxy resin containing a larger amount of curing agent than the above is coated by a coating device 2, and only the coating is cured by heating by a surface curing heating device 3 such as a heating furnace or a hot water tank.

イムに差があるほど操業し易い。At this time, the layer thickness of the coating changes to 0.02 as the fiber bundle diameter changes.
It can be changed from mm to about 1.0 mm. However, if the coating is too thick, depending on the temperature conditions within the surface curing heating device 3, the viscosity of the resin may decrease and the resin may move, resulting in uneven coating thickness, so care must be taken. The manufacturing temperature of the surface hardening heating device 3 depends on the fffi of the resin used, but it should be operated at a temperature at which surface hardening is completed in the furnace and does not exceed the glass transition point of the epoxy. This temperature range is, for example, about 50°C to 250°C. Also, for example, gel time is used as an index to express the curing speed, but if the gel time is close, the coating and the inside will harden in the same way.
As a result, the coating becomes thicker and there is less uncured internal portion, so that the cable-like preform does not have sufficient flexibility. The combination of thermosetting resins used in this case is easier to operate as there is a difference in gel time.
