Problems solved by technology

[0033] However, to combine density and E L / G TL It is very difficult to adjust the two values ​​to the appropriate value for the instrument
For example, even if the above-mentioned composite material composed of chaga wood powder and epoxy resin, ABS resin, acrylic resin, etc. is compressed to adjust its density to a predetermined value, because E L / G TL There is no relationship between value and density, so it is difficult to adjust E L / G TL value
Therefore, it takes a lot of labor and time to manufacture a material having the desired vibration characteristics, thus increasing the cost.

example 1

[0091] The honey resin aqueous solution was applied to the entire surface of 600 wooden (youous wood) board members each having a length of 180 cm, a width of 90 cm and a thickness of 0.6 mm. Align the fiber directions of these wooden board parts and place them in a pile. Then, at a temperature of 130°C and 20kg / cm 2 Hot pressing under high pressure. The melamine resin hardens and the planks are glued together to form a laminate. The density of this laminate is 0.5g / cm 3 . Utilize slicer, on the vertical direction relative to the top face of wood board pile, laminated body is sliced ​​along the fiber direction of wood board, obtain laminated wooden board parts (the length of each board is 150cm, width is 30cm, thickness is 0.6 mm). Then, these laminated wooden board members were immersed in the same aqueous solution of melamine resin as used in the above process for 2 hours to impregnate the wooden board members with melamine resin. Then align the fiber direction of thes...

[0093] The honey resin aqueous solution was coated on the entire surface of 600 wooden board (youous wood) parts, each of which had a length of 180 cm, a width of 90 cm, and a thickness of 0.6 mm. Align the fiber directions of these wooden board parts and place them in a pile. Then, at a temperature of 130°C and 10-20kg / cm 2 Hot pressing under high pressure. The melamine resin hardens and the planks are bonded together to form a laminate with a density of 0.6g / cm 3 . Using a slicer, slice the laminate along the fiber direction of the planks in a vertical direction relative to the top surface of the stack of planks to obtain laminate parts (the length of each plank is 150 cm, the width is 30 cm, and the thickness is 0.25 mm) . Then, these laminated wooden board members were alternately stacked with paper (0.06 mm in thickness) impregnated with the same aqueous melamine resin solution as used in the above process for 1 hour. The fiber directions of these laminated wooden bo...

Abstract

The present invention provides a method of manufacturing wood elements for musical instruments that have vibration characteristics similar to those of natural woods that are used for musical instruments. The method comprises a laminating step in which a resin is coated onto or is impregnated into a plurality of wooden plate units, fiber directions of the wooden plate units are aligned, and the wooden plate units are stacked and are subjected to thermal pressing so as to be bonded together and produce a laminated body, wherein the thermal pressing is conducted by controlling a pressure so that a density of the laminated body is in a range from 0.8 to 1.4 g / cm<3>.

Description

technical field [0001] The present invention relates to a method of manufacturing a wooden piece for musical instruments, a wooden piece for musical instruments obtained by the manufacturing method, and musical instruments using these wooden pieces. Background technique [0002] In general, natural woods such as granadilla and mahogany are mainly used to manufacture a large number of musical instruments, especially wooden wind instruments such as clarinets. These natural woods are widely used because musical instruments made of these natural woods mentioned above have excellent sound quality. [0003] However, in musical instruments made of natural wood there are the following disadvantages: [0004] -Woods such as eggplant and mahogany, which are basic materials, are rare and are currently frequently endangered; therefore, their cost is correspondingly high. [0005] -Drying is difficult, so it takes a long time to manufacture the instrument (generally about three years);...
