Description
Technical field
The present invention relates to a kind of Stranding-type compound core and manufacture method thereof.
Background technology
Resin-based high strength continuous fiber composite material wire rod, because it has the features such as quality is light, tensile strength is large, heatproof is high, Gao Bimo, coefficient of linear expansion are little, should get more and more people's extensive concerning in electric power conveying, ocean operation, bridge enhancing etc.Composite material is used for advantage in transmission line and day by day shows especially by the many companies particularly headed by CTC company of the U.S., Yuandong Compound Techn Co., Ltd..The composite core technique of current domestic sub-thread club shaped structure is more ripe, but the bar-shaped composite core of sub-thread finds to there is the shortcoming that bending property is poor, security reliability is relatively low in application process, simultaneously because its processing diameter is restricted, when it needs the more heavy in section composite core of more high strength for Great span area, its application is restricted.In order to improve the fail safe of fiber material composite core, meeting simultaneously and using under large span, large length occasion, people begin one's study the composite core and manufacture method thereof that adopt multiply structure.But to so far, do not have Stranding-type compound core to produce ripe manufacture method in batches yet.201020639236.7 compound fiber twisted cables as Tokyo Rope Mfg. Co., Ltd.'s application had previously applied for 201010102161.3 aerial condutors continuous high-intensity fiber resin compounded core and preparation method thereof with my company, first its process mentioned mainly is single composite core is semi-solid preparation, then carries out post bake after strands again and solidifies completely.This processing method is when composite core is stranded, in the single composite core of this semi-solid preparation, unhardened resin from coating layer internal penetration out, the resin that adjacent side stock is mutual soaks each other, and be trapped in the gap of core stock and side stock, solidify through post bake, to make between adjacent line stock (core stock and side stock, side stock and side stock) bonding and integrated, make composite core overall become one very hard bar-shaped, its result compromises the flexibility that twisted wire structure should possess originally.Therefore the method still has the place being worth improving.
