Amendment 2.26.2012 The scope of claims for utility model registration is amended as follows. (1) Slice natural wood to a thickness of 30 μm to 100 μm, and bond the dried sliced sheet onto a glass prepreg heavily impregnated with thermosetting and thermoplastic resin, and apply release paper to both the front and back sides of the sheet. After impregnating the sliced sheet with resin by heating and pressurizing it with A laminated pipe for golf shafts, billiard cues, etc., characterized by being molded by the following conventional method. (2) The composite prepreg according to claim 1 is wound around the outer periphery of the inner layer and intermediate layer composed of high-strength, high-elasticity organic/inorganic fibers and thermosetting/thermoplastic resin, with the glass surface facing outward. 2. The laminated tube for golf shafts, billiard cues, etc. according to claim 1, characterized in that the laminated tube is molded by a conventional method. (3) Slice natural wood to a thickness of 30 μm to 100 μm, dry the sliced sheet, and bond it onto a glass prepreg heavily impregnated with thermosetting /thermoplastic resin, and apply release paper to both the front and back sides of the sheet. A composite prepreg for laminated tubes for golf shafts, billiard cues, etc., which is obtained by impregnating the sliced sheet with a resin by heating and pressurizing the sliced sheet, and then separating a release paper. (4) The composite prepreg for laminated pipes for golf shafts, billiards, etc. according to claim 3, characterized in that one side is laminated with a glass cloth or the like that becomes transparent after molding. The brief description of the drawing has been amended as follows. In lines 3 to 7 of page 15 of the specification, the phrase ``Figure 2 is a perspective view showing...'' has been replaced with ``Figure 1 is a perspective view showing one molding process of the composite prepreg in the same example. 2 is a perspective view showing a sliced natural wood sheet in a first embodiment of a laminated pipe for a golf shaft, billiard cue, etc. and its composite prepreg according to the present invention." In lines 7 to 9 of page 15, the statement ``Figure 3...perspective view'' is corrected to ``Figure 3 is deleted and the missing figure number is given.'' 1st
Delete "5...glass cloth" in the first line of page 6. In the third line of page 16, "A, A'...composite prepreg" is corrected to "A...composite prepreg".

Claims (1)

[Scope of Claim for Utility Model Registration] (1) Natural wood sliced into 30 μm to 100 μm thick sheets and dried, the required number of sliced sheets on a glass prepreg made by thermosetting and heavily impregnated with thermoplastic resin. After applying heat and pressure with a release paper interposed on both sides to impregnate the sliced sheet with resin, the release paper is removed and the sliced sheet is separated from the glass cloth prepreg. A composite prepreg made by pasting glass cloth, etc., which becomes transparent after molding, is wound around a core metal so that the glass surface faces outward, heated and pressurized, and then molded using a conventional method. Laminated pipes for golf shafts, billiard cues, etc. (2) The composite prepreg according to claim 1 is wound around the outer periphery of the inner layer and intermediate layer composed of high strength, high elasticity organic or inorganic fibers and thermoset or thermoplastic resin, with the glass surface facing outward. The laminated tube for golf shafts, billiard cues, etc. according to claim 1, characterized in that the tube is molded by a conventional method. (3) Slice natural wood into 30 μm to 100 μm thick slices, dry the sliced sheets, and paste the required number of sheets onto glass prepreg that has been heat-cured and heavily impregnated with thermoplastic resin. A golf shaft or a billiard club, characterized in that the sliced sheet is impregnated with resin by heating and pressurizing it with a release paper interposed therebetween, and then the release paper is removed and the sliced sheet is separated from the glass cloth prepreg. Composite prepreg for laminated pipes by Yu et al. (4) The composite prepreg for laminated pipes for golf shafts, billiard cues, etc. according to claim 3, characterized in that one side is laminated with a glass cloth or the like that becomes transparent after molding.
