Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Technology] The present invention relates to a method of manufacturing a vibrator for plucking the strings of a stringed instrument, for example, a guitar.

[Problems with conventional technology]

Picks for stringed instruments, such as guitar picks, have traditionally been made of acrylic resin or polycarbonate resin.

Synthetic resins such as vinyl chloride resin and nylon resin are used as the first
Molded into the shape shown in the figure, or 1111IIl
It was manufactured by punching out the following synthetic resin plates as described above.

If these conventional vicks were required to have elasticity, they would inevitably become thicker, making them difficult to play, and they also had the disadvantage that the tips of the vicks would become deformed and worn out prematurely.

This is also a drawback of the flexibility of synthetic resins.

[Summary of the invention]

In this invention, the weight ratio of carbon fiber and synthetic resin is 0.2.
By creating a composite plate with a diameter in the range of 5 to 2.5 and punching it into the desired shape to make a bulge, it is thinner than conventional plates, has improved elasticity, and has very little wear. manufactured.

This is something that can be provided.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail.

(Example 1) As shown in Figure 2, high-strength carbon woven by warp and weft! A thin fabric 2 with a thickness of 0.3 mm,
Impregnated with epoxy resin at a weight ratio of 1:1, laminated with a plurality of glass plates or metal plates treated with a mold release agent (hereinafter referred to as mold release agent treated plate 3), and further,
A similar mold release agent-treated plate 3 is placed on the upper surface, and a slight pressure is applied to harden and mold under heating conditions of 130°C for 1 hour, followed by punching to form a mold 1 having the shape shown in Figure 1. Obtained.

(Example 2) In Example 1, a plurality of thin fabrics 2 of 0.31 ID were laminated, but instead, a thick fabric was used, and this was impregnated with epoxy resin at the same weight ratio as in Example 1, The material was heated and pressed in the same manner, and after hardening, was punched out to obtain a big 1 having the shape shown in FIG.

(Example 3) In Example 1, a plurality of 0.3 mm thin fabrics 2 were laminated, but instead of this, carbon fibers aligned in one direction were laminated so as to intersect with each other. It was impregnated with an epoxy resin at the same weight ratio, heated and pressurized in the same manner, and after curing was punched out to obtain a Bic 1 having the shape shown in FIG.

(Example 4) In Example 1, a plurality of 0.3 mm thin fabrics 2 were laminated, but instead, as shown in Fig. 3, epoxy resin was applied to carbon fibers aligned in one direction. A unidirectional prepreg sheet 4 was produced by impregnating it at the same weight ratio as in Example 1, and a plurality of sheets of this prepreg sheet 4 were laminated so that the fibers crossed each other, and heated and pressurized in the same manner as in Example 1.
After curing, punch out a big 1 in the shape shown in Figure 1.
I got it.

(Example 5) The unidirectional prepreg sheet 4 obtained in Example 3
A plurality of sheets, for example, two sheets, are laminated so that the fibers intersect with each other, and the thin fabric 2 impregnated with the epoxy resin in Example 1 is laminated on the upper and lower surfaces of the cloth, and heated and pressurized in the same manner as in Example 1. After curing, a punch 1 having the shape shown in FIG. 1 was obtained by punching.

In addition, glass fiber was added to each of the above examples,
Alternatively, by adding aromatic polyamide or adding these two at the same time, heat and pressurize in the same manner as in Example 1, and after curing, handle to obtain a tong 1 having the shape shown in Fig. 1. In other words, it is extremely effective in terms of design.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to obtain a beak for a stringed instrument that is thinner than conventional ones, has good elasticity, and has very little wear.
