Problems solved by technology

The problem of this kind of artificial feather is: the strength of the feather stalk is not good; the wing unit (pinna) will be overweight, and overweight pinnae is a taboo in badminton production, which will cause top-heavy problems and seriously affect flight performance
The problems of this kind of artificial feathers are: the thin sticks of moso bamboo are too heavy, the artificial feathers made will be overweight when used in badminton, and the mechanical strength is not enough; the carbon fiber without composite treatment is too brittle
[0018] 2. It is necessary to find or manufacture a material or structure with sufficient strength and lightness
However, after many trials, it was found that there are two major problems with this kind of badminton: one is that the strength of the feather stem is still lacking, and its durability is not better than that of a shuttlecock made of goose and duck feathers; Need to be further strengthened
[0031] Because the shuttlecock is very sensitive to the weight of the ball body, if the reinforcing member is too large, the shuttlecock made of artificial feathers will easily lose its practicality due to overweight. A small-sized reinforcing member that reinforces the weak point of the connection with the feather stem to minimize the weight of the artificial feather

Embodiment 1

[0048] A kind of artificial feather of the present invention, as figure 1 and figure 2 As shown, its pinna 12 is made of polyester spinning cloth, and the feather stem 11 is a leather-wrapped structure, the feather stem inner core 21 is made of glass fiber reinforced composite material, and the outer cladding 22 is made of polypropylene plastics, Polypropylene plastic is also called PP plastic, and the artificial feather has a reinforcing member 13 of a thin thread stitching structure positioned at the feather stalk head position.

[0049] The specific manufacturing process of this artificial feather is:

[0050]In the first step, the continuous filament glass fiber is selected as the reinforcing material, the unsaturated polyester resin is selected as the matrix material, and the thin rod of the glass fiber reinforced composite material is produced by the pultrusion process, which is used as the inner core 21 .

[0051] In the second step, PP plastic is selected as the mat...

Embodiment 2

[0059] A kind of artificial feather of the present invention, its cross section is as image 3 As shown, the pinna 12 is made of polyester spun cloth, the feather stem 11 is a leather core structure, the inner core 21 is made of glass fiber reinforced composite material, and the outer cladding 22 is made of unsaturated polyester resin .

[0060] The feather stalk with leather core structure is manufactured by resin pouring process, specifically:

[0061] In the first step, the continuous filament glass fiber is selected as the reinforcing material, the unsaturated polyester resin is selected as the matrix material, and the fiber-reinforced composite material wire is produced by the pultrusion process, and the wire is cut into a suitable length to be used as the inner core 21 .

[0062] In the second step, choose a grammage of 30g / m 2 The polyester spinning cloth of left and right is cut into applicable shape and size, and is processed as pinnae 12 through hot edge processing...

Embodiment 3

[0068] A kind of artificial feather of the present invention, as Figure 4 As shown, its pinna 12 is made of a polyester diaphragm, and the feather stem 11 is a leather-wrapped structure. The inner core 21 is made of a reinforced composite material mixed with glass fibers and spinning fibers, and the outer cladding 22 is made of nylon. Made, also called PA plastics, this artificial feather has a reinforcing member 13 of the membrane pressing structure that is positioned at feather stalk head position.

[0069] The manufacturing process of this artificial feather is basically the same as in Embodiment 1, but the reinforcement member 13 is slightly different, specifically:

[0070] ...

[0071] The sixth step is to cut a piece of lightweight plastic film with a size of about 14mm×8mm, and press this film on the head of the feather stalk 11. The film and pinna will cover the head of the feather stalk, and glue the film , pinna and pinnae are bonded firmly, and the plastic film ...

Abstract

The invention relates to a special man-made feather for a badminton, which consists of a feather stem (11) and a pinna (12). The feather stem (11) is a structure composed by an inner core (21) and an outer wrapping layer (22) which wraps the inner core, wherein the inner core (21) contains resin base composite materials reinforced by fibers, the pinna (12) is made independently and connected with the feather stem (11) through technical methods of adhesion, thermocompression bond or plastics welding and the like, or the pinna (12) and the inner core (21) are connected together in advance through technical methods of adhesion, thermocompression bond or plastics welding and the like, and then the periphery of the inner core (21) connected with the pinna (12) is coated with the outer wrapping layer (22). Thin bars of resin base composite materials reinforced by fibers, which are made through pultrusion technology, are most applicable to making the inner core; and the outer wrapping layer is made of plastic materials or foam plastic materials. When necessary, at least one reinforcing component with the function of reinforcing connection can be arranged between the feather stem (11) and the pinna (12). The man-made feather is very light in weight and very high in strength, and each indicator fundamentally achieves or exceeds goose and duck feathers. The invention also relates to the badminton made of the man-make feather.

Description

technical field [0001] The invention relates to an artificial feather, in particular to an artificial feather for shuttlecocks, and also to a shuttlecock made of the artificial feather. Background technique [0002] In early 2005, the International Badminton Federation proposed a package of reforms, including the issue of using artificial feathers to make balls. At the beginning, it was mainly out of environmental protection considerations, because badminton is currently the only ball made of animal hair in the world. Now, bird flu has caused the production of goose and duck feathers to shrink, and the cost of badminton has increased significantly. In addition, the shuttlecock made of goose and duck feathers has poor durability and consumes a lot, which is not conducive to the popularization of badminton. The International Badminton Federation has been actively seeking artificial balls that can replace goose and duck feather materials. [0003] When a traditional badminto...
