性樹脂線状態を複数本撚り合わせたロープの製造法に関
する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a fiber-reinforced thermoplastic resin wire having excellent lightness, flexibility, and corrosion resistance, which is optimal for use in fields such as civil engineering, construction, and the ocean. And a method for manufacturing a rope in which a plurality of ropes are twisted.
〈従来の技術及びその欠点〉 近年線状体として、従来より使用されているスチール
等の金属材料に代り、軽量性、耐食性に優れた繊維強化
プラスチックが提案されている。<Conventional Technology and Its Defects> In recent years, fiber-reinforced plastics excellent in light weight and corrosion resistance have been proposed as a linear body in place of conventionally used metal materials such as steel.
しかし、かかる繊維強化プラスチックのなかで、エポ

き取ることが困難なため、運搬、取扱いが不便であると
いう欠点を持つ。However, among such fiber-reinforced plastics, those using a thermosetting resin such as an epoxy resin or an unsaturated polyester resin as a matrix generally have poor flexibility, and are restricted in use in a bent portion, and have a small diameter. And it is difficult to wind up, so there is a drawback that transport and handling are inconvenient.

連続的に製造するには、技術的に極めて困難である。On the other hand, using a thermoplastic resin as a matrix, flexibility, a linear body with improved flexibility has been proposed, for example, reinforcing fibers are introduced into a melting tank of the thermoplastic resin, and impregnated with the thermoplastic resin. After that, it is conceivable to twist a plurality of linear bodies formed by shaping, but it is disadvantageous in terms of energy cost, because it is difficult to keep the amount of thermoplastic resin attached to the reinforcing fiber constant, There is a problem that stable quality cannot be obtained. Also, (1) a method of forming a linear body to be shaped after impregnating a reinforcing fiber with a thermoplastic resin using a fine powder of the thermoplastic resin (US Pat. No. 4,680,224)
(2) A method of forming a linear body in which reinforcing fibers are introduced into a crosshead die connected to a thermoplastic resin extruder, and the thermoplastic resin is simultaneously impregnated and shaped (Japanese Patent Application Laid-Open No. Sho 62-60625). U.S. Pat. No. 4,439,837) has been proposed. Regarding (1), in order to obtain safe impregnation conditions, it is necessary to strictly control the quality of the fine powder, so that the cost becomes a problem. In the case of (2), there is a disadvantage that it is necessary to strictly control the resin supply amount and the temperature, and it is very difficult to stably perform continuous operation. As described above, the thermoplastic resin is generally inferior in workability as compared with the thermosetting resin, so the reinforcing fibers are uniformly dispersed, and the impregnating property in which the thermoplastic resin is sufficiently penetrated is good and stable. It is technically extremely difficult to continuously produce a fiber-reinforced thermoplastic resin linear body having a good quality.

樹脂を完全に浸透させることは難しく、補強繊維が熱可
塑性樹脂でぬれていない、いわゆる含浸性の不良な部分
が生じ、線状体としての機械的物性に影響するという問
題点がある。Further, in the above method, it is difficult to completely infiltrate the thermoplastic resin into the inside of the reinforcing fiber bundle, and the reinforcing fibers are not wet with the thermoplastic resin, so-called poor impregnating portions occur, and the machine as a linear body is produced. There is a problem of affecting physical properties.
