Special man-made feather for badminton and badminton made thereby

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...

AI Technical Summary

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
