Description
Technical field
The present invention relates to the special-purpose artificial feather of a kind of shuttlecock, the invention still further relates to the shuttlecock of processing by this artificial feather.
Background technology
Adopt artificial material to replace natural goose duck feather to make the ideal that shuttlecock is industrial circle and badminton circle.Because the durable resistance of goose drake feather shuttlecock is too poor, causes the sportsman to change the shuttle again and again, and the cost of playing ball is improved greatly; Goose drake feather shuttlecock production technology cost numerous and diverse, material itself is also higher simultaneously.But the technical difficulty that this material replacement is hidden common people by no means can be imagined.Industrial circle is carried out relevant research work and is surpassed 20 years, but up to the present, the shuttlecock that also has no a kind of artificial material to replace the goose drake feather to process reaches the level of high-quality goose drake feather shuttlecock on combination property.The combination property of existing plastic shuttlecock has satisfied not level good amateurish competitor's specification requirement slightly at all, is abandoned by professional athlete especially.Up to 2007, just begin to occur having the shuttlecock special man feather (or claiming artificial feather) of practical value; To the end of the year 2009, the shuttlecock listing of adopting artificial feather to process is arranged.But the shuttlecock that this employing artificial feather is processed still exists, and rotary speed is not enough, complex manufacturing or overweight problem, does not still reach the level of high-quality goose feather ball fully.
Shuttlecock is that a finesse in football skills degree to the ball article requires very high product.The sportsman has turned out the very fine and smooth experience that impacts in long-term exercise and match.Thisly impact experience and be the basis, comprise weight, ball speed, rotation, high clear flight track, the stability of dropping shot, chop the chop and roll, bat feel, batting sound, accuracy in placement exactness or the like with the natural goose feather ball of high-quality.The artificial material shuttlecock be exactly will be on these factors as much as possible near the natural goose feather ball of high-quality.
Influence the shuttlecock combination property, have following seven big key elements at least: weight, distribution of weight, position of centre of gravity, spheroid support strength, positive wind resistance (or claiming axial wind resistance), around axle wind resistance and anti-fight endurance.Correspondingly just produce three big technical barriers: material closes, structure is closed and technology is closed.Any one of this seven big key element and three big technical barriers can not be up to standard, and shuttlecock just can not passive movement person be accepted, and also just is difficult to achieve success commercial.Therefore when a kind of shuttlecock new technology of examination is whether practical, carry out multifactorial evaluation from above-mentioned seven big key element three disasters passes.In other words: slight shuttlecock is actually a system engineering, has comprised a plurality of subsystems, and tight association between each sub-systems influences each other, and the small adjustment of any one subsystem all can drive the change of total system combination property.Surpass the patent specification in 20 years from the span that retrieves, the overwhelming majority is the independent transformation to a certain subsystem, and mostly is based on theoretical imaginary design, without actual verification.So almost do not have practicality all, perhaps can't realize.Also this reason just, just go through 20 surplus year, by the end of 2007, except goose duck feather ball and the defective plastic shuttlecock of performance, have no the novel badminton appearance of tool practical value.
Wherein wt, distribution of weight and rotation are the most scabrous key elements in the present ball material manual workization process.The ball skirt portion of existing plastic shuttlecock and artificial feather is mostly overweight.The center of gravity of shuttlecock preferably drops near bulb and the spheroid connecting portion.If the skirt section is too heavy, upper shift of gravity center, shuttlecock very easily rolls, and the closer to the shuttlecock skirt section apical position, just big more to overweight susceptibility because the moment of this position is maximum; If the skirt section kicks the beam, center of gravity too moves down, and then bulb tenesmus also influences performance.
Shuttlecock is very responsive to the variation of weight, and its susceptibility reaches the 0.1 gram order of magnitude, that is to say at some key positions, as long as the weight of 0.1 gram changes the great change that will cause the shuttlecock overall performance.And for the monolithic feather, the susceptibility of weight has then been reached 0.01 gram, and that is to say that if every feather increases by 0.01 gram, near the reducing in then whole ball skirt section adds 0.15 gram, such weight changes the flying quality with the heavy damage shuttlecock.And feather can further be divided into two zones to the sensitizing range of weight: accessory pinna district (the A district among Fig. 1) and pen feather district (the B district among Fig. 1), accessory pinna district have comprised the upper half (with accessory pinna body contact portion) of accessory pinna body and plumage stalk; The pen feather district is exactly the following half of plumage stalk.The accessory pinna district requires the harshest zone to weight in the whole shuttlecock.From engineering; The weight in shuttlecock skirt section (generally being made up of tens accessory pinnas) is more gently good more; Because do product to such an extent that gentlier be a high-leveled and difficult technical problem under the prerequisite of enough support strengths guaranteeing that the shuttlecock spheroid has; And after having grasped the skirt section manufacturing technology of ultralight, carry out counterweight again and then be easy to solve.The weight that alleviates the accessory pinna district can be set about from accessory pinna body and plumage stalk the upper half respectively.Some artificial material shuttlecock is for loss of weight, just ball skirt pole (or plumage stalk) make very carefully, ball skirt (or accessory pinna) does very thinly.Weight is up to standard, but insufficient strength.Generally between 0.09g～0.12g, wherein the accessory pinna district if the accessory pinna district surpasses 0.07 gram, will influence whole ball performance, only if adopt 15 feather system balls greatly about 0.05 gram to shuttlecock with the single weight of standard goose duck feather.Even if restrain and adopt 15 feather system balls, the weight in accessory pinna district can not surpass 0.075---whole ball skirt weight preferably is no more than 1.10 grams.
Whether shuttlecock can stablize rotation is very crucial.Being used for promoting shuttlecock around the axle wind resistance pivots.Shuttlecock flight the time is pivoted and not only can be stablized its flight course, and can effectively consume the part kinetic energy that flies, and during by hard smash, certain decelerating effect is arranged at shuttlecock, makes its flying speed more meet the requirement of motion.
Sum up in the point that a bit: the real core of artificial material shuttlecock is exactly the weight issue of ball skirt portion, as long as the weight issue of ball skirt has solved, other problem is just known about the basis of determining.Specific on the artificial feather being exactly the weight issue that solves accessory pinna district part.We can say that under the prerequisite of proof strength, the loss of weight that each person of outstanding talent of accessory pinna part is restrained all is valuable.
In addition; Influencing the shuttlecock flying quality and also have that do not noted, a trickle but The key factor very: if the wind resistance jumping phenomenon by the people---ball skirt support bar is too soft; Then the shuttlecock skirt section drastic deformation can occur being impacted moment energetically, recovers normal immediately again, in this process of one of contracting; Wind resistance produces acute variation; Make the shuttlecock flying speed produce the moment sudden change, perhaps the sportsman can not directly feel the variation of this speed, but flight and the standard shuttlecock that can obviously realize shuttlecock are distinguishing---go out can become strange, drop point of feel of the ball feel and understand inaccurate.
Thus, the exploitation of artificial material shuttlecock faces conditioning each other of seven big key elements, three big difficulties forever, only considers that performance in a certain respect is not all right.
The plumage stalk of the artificial feather of practical application at present has two kinds, and a kind of is to adopt extraordinary nylon to process; Another kind is to adopt the fibre reinforced composites bar and coat the plastic cement surrounding layer to make the plumage stalk, is exactly the plumage stalk of so-called suitcase cored structure, and on September 16th, 2009, disclosed 200810034704 patent specifications had detailed introduction to this plumage stalk.But above-mentioned two kinds of artificial feathers all have defective separately.
There is overweight problem in the plumage stalk that extraordinary nylon is processed.The extraordinary nylon plumage of practical application at present obstructs single weight and has reached more than 0.12 gram, adds accessory pinna and has just surpassed 0.15 gram, so have to adopt 15 feather system balls (standard is 16).But reduce weight like pipe, then its intensity is not much of that again.Although adopt 15 feather system balls, thus the ball skirt portion still excess weight slightly---the ball skirt of this shuttlecock nearly weighs 1.10 grams---having influenced the flying quality of shuttlecock to a certain extent---greatly and mainly shows: (1) batting feel lays particular stress on; (2) the shuttlecock batting is later sluggish; Very easily roll when (3) dropping shot, can roll during perhaps with racket top bead.Above-mentioned just these defectives; Although make the sportsman not be ready very much still to adopt that this shuttlecock---the combination property of this shuttlecock has surmounted existing whole ball skirt plastic shuttlecock far away; And, can reach more than 2 times of common goose duck feather ball its service life.
The plumage stalk that the fiber-resin composite bar that adopts plastic cement to coat is processed also has its intrinsic shortcoming.Because this superfine fiber-resin composite bar can only adopt pultrude process to make; So can't make certain tapering---adopt grinding method can process a big little tapering shape; But can seriously reduce its intensity---therefore; This bar just can not be done too slightly, and not so the accessory pinna district of feather will be overweight.And the restriction on this just weight just causes this plumage stalk softer relatively, and just rigidity is not enough---above-mentioned said wind resistance jumping phenomenon will appear in the shuttlecock of being processed by this plumage stalk, causes shuttlecock to go out that the feel of the ball feels strange, poor placement is true.
In 200810034704 patent specifications of introducing above-mentioned suitcase cored structure plumage stalk, also mentioned the fiber-resin composite bar that direct employing obtains through pultrude process and made the plumage stalk, but this patent specification points out not reach on intensity and durable resistance without the fiber-resin composite bar that the plastic cement surrounding layer coats the level of natural goose drake feather.Above-mentioned prejudice has then been corrected in my latest find; And constituted technical foundation of the present invention: under the cooperation of suitable accessory pinna material; Directly adopt the fiber-resin composite bar to make the plumage stalk and obtained beat all effect---adopt biplate applying foaming elastoplast sheet material (also can be called the flexible foaming plastic sheet) to make accessory pinna; The fiber-resin composite bar that cooperation is processed by pultrude process is made the plumage stalk, and the made artificial feather of this combination has very excellent performance.The shuttlecock of processing by this artificial feather; On combination property, surmount the shuttlecock that existing extraordinary nylon plumage stalk shuttlecock and above-mentioned suitcase core composite plumage stalk are processed far away; Reached the equal performance of standard natural feather ball, be expected to reach and surmount the performance of high-quality goose feather ball---can be better on durable resistance.
Biplate applying foaming elastoplast sheet material cooperates the made artificial feather of combination of fiber-resin composite bar to have the excellent comprehensive performance; Can't and the fiber-resin composite bar have corresponding excellent properties with other material fit why? Analyze as follows:
No matter be artificial feather or natural feather; What broken the most easily is exactly accessory pinna district (the A district among Fig. 1); Or the accessory pinna body is broken or plumage stalk the upper half is interrupted---certainly, when plumage stalk toughness was not enough, pen feather district (the B district among Fig. 1) also was easy to fracture; Hit energetically but comparatively speaking, the pen feather district is very little.When adopting general rigid sheeting to make accessory pinna, if the accessory pinna district is hit, impact force acts directly on the plumage metulae body basically, so the plumage that is connected with accessory pinna stalk just is easy to interrupted.But adopt the flexible foaming plastic sheet of biplate attaching type to make accessory pinna, situation is just fully different.Generally about 1.0mm, so thick flexible foaming layer has good cushioning effect for the artificial feather of actual fabrication of the present invention, the thickness of its flexible foaming layer.If the accessory pinna district is hit, the foamed plastic sheet material with favorable elasticity can sponge most of impact force, thereby has protected the plumage stalk in accessory pinna district can not interrupted easily.
When anti-impact problem and be able to solve after, other performance indications of fiber-resin composite bar have just satisfied other requirement of artificial feather just.Such as, adopting diameter is the pultrusion bar making plumage stalk of the carbon-fibre reinforced epoxy resin of 0.80mm, cooperates two flexible foaming plastic sheets applyings to process accessory pinna and is coated on plumage stalk the upper half in the accessory pinna matrix.The artificial feather that this combination is processed, the weight in its monolithic feather accessory pinna district can be controlled at below 0.065 gram, and the rigidity of plumage stalk then can compare favourably with goose duck feather stalk.The shuttlecock that adopts 15 or 16 this artificial feathers to process has been eliminated many defectives of existing various artificial feather balls fully, and combination property has reached the peer-level of the natural ball of standard, then surmounts the natural feather ball on the durable resistance.
Comparatively speaking; If adopt the technical scheme (i.e. 200810034704 patent schemes) of existing suitcase cored structure; Because the weight factor of outsourcing plastic cement cortex; Must be reduced to the diameter of the pultrusion bar (or pultrusion bar of glass fiber reinforcement unsaturated polyester) of the carbon-fibre reinforced epoxy resin that is used as inner core below the 0.65mm, the accessory pinna district weight of this moment could satisfy standard-required.But so, the rigidity of plumage stalk is just obviously not enough, and the wind resistance jumping phenomenon has just occurred.
In sum; The cooperation of biplate attaching type flexible foaming plastic sheet and fiber-resin composite bar is a kind of exquisite coincidence: the performance of preceding a kind of material has remedied the defective of back a kind of material ripping, thereby makes other advantage of a kind of material in back be able to bring into play rightly.This combination is not conspicuous: actual test finds that though the fiber-resin composite excellent combination property, resistance to impact is relatively poor, so adopt this material plumage stalk never to move towards practical.I adopt this material to cross many kinds of balls, am all interrupted very soon.Just abandon this material afterwards and made the plumage stalk.For making a data model, there is not other Available Material at hand recently, just will be with adopting this fiber-resin composite bar to make an appearance ball again, accessory pinna has adopted biplate attaching type flexible foaming plastic sheet just.Examination when beating several have a brainwave down like drive, but discovery is not broken as usual, is all beyond one's expectations.Obviously, the sort buffer action effect of flexible foaming sheet material is arriving of being difficult to expect, therefore also can't obviously find the excellent technique effect of this combination.
Below the disclosed special routine specification of several examples also all related to the artificial feather ball or be used for the artificial feather of shuttlecock, but all there is deficiency in these---be not that plumage stalk insufficient strength is exactly that shuttlecock is overweight.
It is such that on June 24th, 1987 related to a kind of artificial feather among the disclosed patent specification CN85108694: the plumage stalk is a kind of suitcase cored structure or sandwich; Contain reinforcing fibre; Carbon fiber particularly, remainder is plastics, the surrounding layer of accessory pinna and plumage stalk is an integral body; Parts of plastics alleged in the book just is described, parts of plastics is through the moulding of mould pressing process disposable thermal.This sandwich is easy to layering, makes on its anti-bending strength to be short of to some extent, and plumage obstructs when bearing horizontal hitting power, very easily cracking.The most important thing is; With this minute sized product of mould pressing process moulding is very difficult; With regard to current technical merit; The complete plastic sheeting that will be stably be lower than 0.2mm with the mould pressing process molding thickness almost is impossible, but not the film thickness of expansion type is when surpassing 0.2mm, and the accessory pinna of processing can be overweight.
Mould pressing process is often used in the mechanical fitting of producing some plastic materials, and this technology has certain condition: be exactly only to be applicable to the lumps plastic material, and be not suitable for the strip goods.If embedded component is arranged simultaneously, this embedded component must have the head that exposes bearing on the direction of pressure, so that mould can clamping.And the situation in patent specification CN85108694 is, the plastics that will be used for surrounding layer wrap with inner core material in advance is in the same place, and heating makes plastics wrap layer fusing and forms surrounding layer again.Is problem: flow direction in so little space, how to control plastics? How to control the thickness and the uniformity thereof of surrounding layer or plastic sandwich? After particularly plastics are heated; Hope on the one hand it to flow and film forming encases core or form the upper strata of interlayer to form that plastics that accessory pinna guarantees plumage stalk top on the one hand again do not flow out; How to accomplish? How to guarantee the core material non-migration? How to make full-bodied plastic melt flow into thickness below 0.2mm the slit and form accessory pinna? These all are that mould pressing process can't resolve at all, and this is proved by plastic processing theory and practical experience.This just means that plumage stalk and accessory pinna must be made independently member, with the prior moulding of different processes.
Related artificial feather is made up of plumage bar and accessory pinna in 032578210 patent specification of authorizing on August 25th, 2004, wherein accessory pinna again by about two plate sheet materials constitute, two plate sheet materials dock (not being face-to-face applying) mutually on the plumage bar.The feasibility of this technical scheme is very low: accessory pinna and plumage bar be connected technology and bonding strength all cannot solve; Simultaneously, for enough grip strength are arranged, the plumage bar will be done slightlyer, and this will inevitably cause excess weight.
The artificial feather that relates among the disclosed patent specification CN200520015738.1 on June 28th, 2006 is such; The plumage bone of getting natural feather is made the plumage stalk, has the assistant unit (being accessory pinna) of reinforcement with injection-moulding plastic, and both are combined into feather.The problem of this artificial feather is: plumage stalk intensity is not good; Assistant unit (accessory pinna) can be overweight, and accessory pinna is overweight to be that shuttlecock is made and bigly avoided, and can form top-heavy defect, has a strong impact on flying quality.
The artificial feather ball that relates among the disclosed patent specification CN200520123581.4 on January 17th, 2007 is such: go up fluting ball skirt pole (being the plumage stalk), be connected with ball skirt (the being spherical crown) heat seal of integral body, become a shuttlecock spherical crown.Handle like this, bonding strength can be improved, but the plumage at slotting position place stalk intensity is extremely low, is easy to fracture.Its ball skirt pole adopts injection-moulded plastic or carbon fiber material to process.The pole that injection-moulded plastic is processed, its rigidity is not enough; And too crisp without the pure carbon cellulose fiber of Combined Processing, its toughness is not enough, and the artificial feather of processing is also impracticable.
The artificial feather that relates among the disclosed patent specification CN94245400.6 on March 6th, 1996 is such: the accessory pinna that sticker is processed by the cloth yarn on the plumage stalk that materials such as mao bamboon or carbon fibre are processed forms an artificial feather.The problem that this artificial feather exists is: the thin rod of mao bamboon is too heavy, can be overweight when the artificial feather of processing is used for shuttlecock, and mechanical strength is also not enough; Do not have the reinforcement of sticker between plumage stalk and cloth yarn, firmness is not enough.
Artificial feather on November 11st, 2009 disclosed patent specification 2008800014168: adopt nonwoven as accessory pinna, insert mould, injection moulding plumage stalk.This artificial feather is inevitable overweight.
Make a brief account in the face of fiber-resin composite down.
Said fiber-resin composite also can be called resin-based fibrous composite, resin base fiber reinforced composite material or fiber-reinforced resin matrix compound material; Be meant with chopped strand or continuous fiber and fabric enhancing thermosetting or thermoplastic resin matrix, through the material that is composited.Can process different section bars with this composite through pultrude process, expressing technique, injection technique or spray technology etc.Adopt the resulting composite material section bar of different process very big difference to be arranged in performance.The composite bar that wherein adopts pultrude process technology to make is best on rigidity intensity, is suitable for artificial feather of the present invention most; The composite bar that injection technique is made only is applicable to thermoplastic's resin, and is slightly inferior on rigidity intensity, but can process a big little tapering, also can be applied to artificial feather of the present invention.Only be with fibre bundle and resin carry out that simple layer is closed and the plied timber that obtains not in the category of this fibrous composite notion; Its difference is: theoretically; Every fiber of fibrous composite is all wrapped up by resin, and the fibre resin plied timber then only is that layer splice grafting touches the combination on the interface, and both intensity cannot be mentioned in the same breath; It is fragile relatively that the layer of laminate closes face, easy to crack when stressed.Certainly, composite also has and adopts die press technology for forming, but this technology generally is applicable to and makes certain thickness sheet material; Specifically: with glass fiber yarn (generally being glass mat) lay in having applied in advance on the PE film that unsaturated polyester resin sticks with paste; Cover other PE film then above that, through abundant kneading and necessary slaking reach tack-free till, throw off the PE film then; Be cut into the size of requirement, be positioned over warming and pressurizing moulding in the metal pair mould.Die pressing is specially adapted to the processing of composite material sheet, and is when being used to make bar, very easy to crack.
The resin-based fibrous composite combine fiber and resin separately advantage and have particular performances, topmost is exactly high-strength light, particularly tensile strength, bending strength are fine.But shock resistance is general, and when particularly processing thin-wall part or ultra-fine bar, shock resistance is lower.Theoretically, any fiber may be used to the resin-based fibrous composite.
Each item mechanical strength index of galss fiber reinforced resin composite is all good; But its apparent density is more much higher than natural plumage stalk; So to make plumage when stalk with it, the cross sectional dimensions of this thin rod than the plumage stalk of natural feather thinner just can guarantee not overweight.When selecting diameter for use is that 0.8mm, length are the thin rod of extruding fiberglass composite of 7.5cm when making the plumage stalk, and the about 0.9g of its single weight cooperates accessory pinna, gross weight 0.12 restrain about.This moment, its mechanical strength can satisfy the actual needs of making shuttlecock.
Carbon fiber-reinforced resin composite materials has the better mechanical strength index, has more performance when making the plumage stalk with it.When selecting diameter for use is that 0.8mm, length are the thin rod of extruding fiberglass composite of 7.5cm when making the plumage stalk, and the about 0.08g of its single weight cooperates accessory pinna, gross weight 0.11 restrain below.This artificial feather can be processed the very superior artificial feather ball of performance.
Aramid fiber and superhigh molecular weight polyethylene fibers are the specific strength special fibres higher than glass fibre, and merely technologically speaking, the plumage stalk intensity that the compound material of the resin-based of these two kinds of fibers is processed is higher. weight is lighter, but cost is higher.Two or more fiber mixed to obtain assorted fibre, strengthen resin with this assorted fibre and process composite, can reach and improve the purpose that performance reduces cost.
Summary of the invention:
The technical problem that the present invention will solve is the special-purpose artificial feather of shuttlecock, and another technical problem that the present invention will solve provides the artificial feather ball of excellent performance.
For solving the problems of the technologies described above; Shuttlecock special man feather of the present invention comprises accessory pinna and plumage stalk; It is characterized in that said accessory pinna is by two relative be combined intos of flexible foaming plastic sheet, and the whole or part of said plumage stalk is wrapped between two flexible foaming plastic sheets; Simultaneously, said plumage stalk adopts fiber-reinforced resin matrix compound material to process.Two flexible foaming plastic sheets can be identical, also can be slightly different, and such as unlike material, different-thickness, different sizes etc.The polyethylene foamed sheet material is to make this flexible foaming plastic sheet preferred materials.
The carbon fiber enhancement resin base composite material bar is an optimal material of making plumage stalk of the present invention, particularly is particularly suitable for artificial feather of the present invention through the carbon fiber enhancement resin base composite material bar that pultrude process obtains.In general, it is best selecting the carbon fiber enhancement resin base composite material bar of external diameter between 0.7mm～1.0mm for use.
Galss fiber reinforced resin based composites bar also is suitable for making the plumage stalk of the artificial feather of the present invention, and the galss fiber reinforced resin based composites bar that particularly obtains through pultrude process is particularly suitable for artificial feather of the present invention.In general, select for use the galss fiber reinforced resin based composites bar of external diameter between 0.7mm～1.0mm all to be suitable for.
The polymer matrix composites bar that aramid fiber and superhigh molecular weight polyethylene fibers strengthen also goes for the plumage stalk of the artificial feather of the present invention.
Obstruct the performance of material or reduce its cost in order further to improve plumage, can strengthen resin with this composite fibre and process composite with two or more fiber mixing together, and then be used for making the plumage stalk.
By chopped strand or mix the nylon rod bar that chopped strand strengthens and also can be used for plumage stalk of the present invention.
Combinations such as that two flexible foaming plastic sheets that constitute accessory pinna can adopt is bonding, hot pressing or Plastic Welding technology combine.In order to promote the cross-brace rigidity of accessory pinna, elasticity can be set in accessory pinna strengthen silk.Method is said elasticity to be strengthened silk be embedded between two flexible foaming plastic sheets that constitute accessory pinna.Generally speaking, it is proper that artificial feather comprises 1 to 3 elasticity enhancing silk horizontal or that tilt, has both played good humidification, is unlikely to cause too much weight to increase again.The general elasticity of plastics silk of external diameter between 0.18mm to 0.26mm all can be used as elasticity and strengthens silk, and most preferred material is the stretchy nylon silk.
The artificial feather of employing the invention described above promptly can be made into the artificial feather ball of excellent performance.
From the needs of optimization production technology and properties of product,, structurally can do some designs especially targetedly for the shuttlecock of processing by the artificial feather of the present invention.
Because the plumage of the artificial feather of the present invention stalk is more tiny; The more bad control of meeting in the slotting hair technical process of whole ball assembling; A kind of bulb connector of specialized designs for this reason; Said bulb connector is used for connecting bulb and artificial feather, and said bulb connector comprises the connecting-rod body of several hollows, and the plumage of artificial feather obstructs with regard to transplanting in the connecting-rod body of these hollows.Said bulb connector is injection molded by plastic material, preferably adopts nylon plastic(s) to make.Said bulb connector can also comprise 1 road or 2 road fixing collars, and said fixing collar can be used for replacing the consolidate coil of shuttlecock waist.
In case of necessity, artificial feather ball of the present invention can also be provided with 1 to 3 road location intensifier coil in ball skirt position, preventing that the laminating order between accessory pinna from being upset, and can promote the support strength in skirt section to a certain extent.
Artificial feather of the present invention has fundamentally solved the contradiction difficult problem between plumage stalk intensity and the weight; The performance that makes shuttlecock special man feather further near and reach the performance of natural feather; Be expected to meet and exceed the performance level of high-quality goose feather, on durable resistance, then surmount to some extent.Existing relatively artificial feather, the artificial feather of the present invention is more easy on production technology, because: the technical process of one, having saved external coating; Two, extraordinary nylon plumage stalk is to adopt injection technique to produce, and injection technique is than numerous and diverse many of pultrude process.
The shuttlecock that adopts the artificial plumage of the present invention to process is in close proximity to traditional goose drake feather shuttlecock on flying quality, can be applied to formal competition fully.Compare existing artificial feather ball, the production technology of shuttlecock of the present invention is also more easy.Have two kinds of artificial feather balls now,, at least one set winding must be set, upset, thereby influence the rotation of shuttlecock with the order that laminates that prevents accessory pinna in ball skirt position because the plumage stalk is softer.The plumage of shuttlecock of the present invention stalk rigidity is higher, the plumage stalk processed of carbon fiber-reinforced resin composite materials particularly, and rigidity is very good, can omit the set winding of position, ball skirt section.If further adopt the bulb connector to connect bulb and artificial feather, then production technology is just easier.
