Abstract
The invention discloses a stranding type combined core. The stranding type combined core comprises a single-layer stranding type combined core and a multi-layer stranding type combined core which are both formed by stranding spiral fiber reinforced resin based combined core strands; each fiber reinforced resin based combined core strand comprises an inner combined core, and 4 to 6 buffering layers wrapping the outside; each combined core is composed of one or a plurality of fibers and thermosetting resin or thermoplastic resin embedded into the fibers; each buffering layer is composed of wrapped fibers or fiber belts and thermosetting resin or thermoplastic resin embedded into the fibers or fiber belts. According to the stranding type combined core, the fiber reinforced resin based combined core strands and strand blocks at all layers can be avoided adhering, so that the bending performance is outstanding.
Description
Technical field
The present invention relates to a kind of Stranding-type compound core.
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, linear expansion coefficient are little, should get more and more people's extensive concerning in electric power conveying, ocean operation, bridge enhancing etc.Composite is used for advantage in transmission line of electricity 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 security of fibrous 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 clad 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 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.
Summary of the invention
The object of the invention is to solve prior art Problems existing, a kind of Stranding-type compound core of function admirable is provided.
The technical scheme realizing the object of the invention is a kind of Stranding-type compound core, and described Stranding-type compound core comprises single-layer stranding type composite core and multilayer Stranding-type compound core; Form by with spiral fiber reinforced resin based composite core stock is stranded; 4 ~ 6 layers of cushion that described fiber reinforced resin based composite core stock comprises composite core and the outer cladding being positioned at internal layer are formed; Described composite core is by one or more fibers and be embedded into thermosetting resin or thermoplastic resin in fiber and form; Described cushion is coated filament or fiber band and is embedded into thermosetting resin or thermoplastic resin in filament or fiber band.
The number of plies that in described Stranding-type compound core, fiber reinforced resin based composite core stock is stranded is 2 ~ 7 layers, and the lay ratio of each layer is 3 ~ 15 times, and outer lay ratio is less than the lay ratio of its adjacent inner layer.
Diameter or the equivalent diameter of described fiber reinforced resin based composite core stock are 1.0 ~ 5.8mm, and the external diameter of described Stranding-type compound core is 5.9 ~ 80mm.
Described Stranding-type compound core comprises 1 ~ 91 strand of fiber reinforced resin based composite core stock.
Have employed technique scheme, the present invention has following beneficial effect: adhesion between fiber reinforced resin based composite core stock of the present invention and between each layer stock block, its bending property is very superior.
Detailed description of the invention
Stranding-type compound core comprises single-layer stranding type composite core and multilayer Stranding-type compound core; Except one composite core stock in bosom, all the other form by with spiral fiber reinforced resin based composite core stock is stranded; 1 ~ 3 layer of cushion that fiber reinforced resin based composite core stock comprises composite core and the outer cladding being positioned at internal layer is formed; Composite core is by one or more fibers and be embedded into thermosetting resin or thermoplastic resin in fiber and form.Cushion is mainly with certain flexibility, temperature resistant grade higher than the filament of 120 DEG C or fiber band, coated mode or braiding or wrapped or vertical bag, semi-cured state before coated, so after entering and rotating solidification mould, have thermosetting resin at high temperature under high pressure or thermoplastic resin oozes out into cushion from composite core.
The stranded number of plies of fiber reinforced resin based composite core stock is 1 ~ 5 layer, and Stranding-type compound core comprises 3 ~ 91 strands of fiber reinforced resin based composite core stocks thus.The lay ratio of each layer is 5 ~ 25 times, and outer lay ratio is less than the lay ratio of its adjacent inner layer.The shape of the joint stock block of each layer can be round also can be various abnormity, as trapezoidal, fan-shaped etc.The diameter of fiber reinforced resin based composite core stock or equivalent diameter are 1.5 ~ 5.0mm, and the external diameter of Stranding-type compound core is 5.0 ~ 50mm.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
