Abstract

An object of the present invention is to provide a woody material for a wind instrument superior in resistance to a moisture change. The woody material for a wind instrument comprises: a plurality of veneers being laminated; and at least one buffer layer comprising a fibrous sheet constituted from a nonwoven fabric or a woven fabric, and an adhesive with which the fibrous sheet is impregnated, the buffer layer being interposed between adjacent two of the plurality of veneers.

First claim

The invention claimed is:

1. A woody material wind instrument tube, comprising:
a plurality of laminated veneers oriented in plural parallel planes;
a plurality of buffer layers made of fibrous sheets constituted from a nonwoven fabric or a woven fabric, and an adhesive with which the fibrous sheets are impregnated interposing between each adjacent two laminated veneers; and
a circular bore and a circular exterior circumference tube made of the alternating laminated veneers and fibrous sheets layers laminated together.

2. The woody material wind instrument tube according to claim 1 , wherein each fibrous sheet is a nonwoven fabric constituted from a synthetic fiber.

3. The woody material wind instrument tube according to claim 1 , wherein an average thickness of the plurality of buffer layers is no less than 0.05 mm and no greater than 0.20 mm.

4. The woody material wind instrument tube according to claim 1 , wherein an average thickness of the laminated veneers is no less than 0.5 mm and no greater than 5 mm.

5. The woody material wind instrument tube according to claim 1 , wherein a principal component of the fiber of the fibrous sheets is a polyester, a polyamide, an acrylic resin, polyethylene, or polypropylene.

6. The woody material wind instrument tube according to claim 1 , wherein a principal component of the adhesive in the buffer layers is an epoxy resin, a phenol resin, a urethane resin, or an acrylic resin.

7. The woody material wind instrument tube according to claim 1 , wherein:
the principal component of the fiber of the fibrous sheets is a polyester; and
the principal component of the adhesive is an epoxy resin.

8. The woody material wind instrument tube according to claim 1 , wherein a percentage content of the adhesive in the buffer layers is no less than 40% by mass and no greater than 90% by mass.

9. A woody material wind instrument tube comprising:
a plurality of laminated veneers; and
at least one buffer layer comprising a fibrous sheet constituted from nonwoven randomly laid fabric, and an adhesive with which the fibrous sheet is impregnated, the buffer layer being interposed between adjacent two of the plurality of laminated veneers.

10. The woody material wind instrument tube according to claim 9 , wherein the fibrous sheet is a nonwoven fabric constituted from a synthetic fiber.

11. The woody material wind instrument tube according to claim 9 , wherein an average thickness of the of buffer layer is no less than 0.05 mm and no greater than 0.20 mm.

12. The woody material wind instrument tube according to claim 9 , wherein an average thickness of the laminated veneers is no less than 0.5 mm and no greater than 5 mm.

13. The woody material wind instrument tube according to claim 9 , wherein a principal component of the fiber of the fibrous sheet is a polyester, a polyamide, an acrylic resin, polyethylene, or polypropylene.

14. The woody material wind instrument tube according to claim 9 , wherein a principal component of the adhesive in the buffer layer is an epoxy resin, a phenol resin, a urethane resin, or an acrylic resin.

15. The woody material wind instrument tube according to claim 9 , wherein:
the principal component of the fiber of the fibrous sheet is a polyester; and
the principal component of the adhesive is an epoxy resin.

16. The woody material wind instrument tube according to claim 9 , wherein a percentage content of the adhesive in the buffer layer is no less than 40% by mass and no greater than 90% by mass.

17. A method for making a woody material of a wind instrument, comprising:
arranging a plurality of laminated veneers in plural parallel planes;
forming a plurality of buffer layers made of fibrous sheets using a nonwoven fabric or a woven fabric;
impregnating the fibrous sheets with an adhesive, interposing between each adjacent two laminated veneers; and
forming a circular bore and a circular exterior circumference tube made using the alternating laminated veneers and fibrous sheet layers laminated together.
