The first side surface 110 and the second side surface 120 have a width direction perpendicular to the longitudinal direction. In one embodiment, the widths of the first side surface 110 and the second side surface 120 are uniform along the longitudinal direction.

引き続き図１及び図２を参照すると、棒状体１００は、第１の側面１１０に設けられた第１の凹溝１１１をさらに含む。第１の凹溝１１１は、第１の側面１１０から厚さ方向に沿って凹設されており、その深さは略均一である。第１の凹溝１１１は、第１の側面１１０の長手方向に沿って延びている。一実施例では、第１の凹溝１１１の溝底面の中心線は、第１の側面１１０の中心線と平行である。第１の凹溝１１１の深さは、５０μｍ～５００μｍとすることができる。第１の凹溝１１１の壁は、溝底面に対して垂直であってもよいし、溝底面と鈍角で交差していてもよくて、第１の凹溝１１１は、溝底よりも幅が小さくない開口部を有する。一実施例では、第１の凹溝１１１の溝幅は、長手方向に沿って均一であり、即ち、第１の凹溝１１１の溝底面の幅は、長手方向に沿って均一である。第１の凹溝１１１の溝底面の幅は、第２の側面１２０の幅以上である。 With reference to FIGS. 1 and 2, the rod-shaped body 100 further includes a first concave groove 111 provided on the first side surface 110.

一実施例では、第１の凹溝１１１の溝底面及び第２の側面１２０は、接触面を形成した後に接着剤が流れる隙間を提供する粗面であるため、接着剤の接触面間の通過及び分布を促進し、接着剤が均一に分布された接着面を形成することに有利である。具体的には、第１の剥離層１１２を剥離すると、粗面化された第１の凹溝１１１の溝底面を得ることができる。粗面化された表面は、ラッピング、切削、エロージョンなどの手段によっても実現できる。 In one embodiment, the bottom surface and the second side surface 120 of the first concave groove 111 are rough surfaces that provide a gap through which the adhesive flows after forming the contact surface, so that the adhesive passes between the contact surfaces.

The beam 13 provided by the embodiment of the present application includes a plurality of rod-shaped bodies 100 according to any one of the above-described embodiments, and the plurality of rod-shaped bodies 100 are arranged in a laminated manner in a predetermined manner. Although FIGS. 6a and 6b schematically show rods 100 arranged in 3 rows and 4 columns, it should be understood that the rods 100 in the beam 13 are not limited to the illustrated arrangement. be. Specifically, the plurality of rod-shaped bodies 100 are arranged in the coaxial direction, that is, the axes of the plurality of rod-shaped bodies 100 are substantially parallel. Among the plurality of rod-shaped bodies 100, the second side surface 120 is in contact with the groove bottom surface of the adjacent first concave groove 111 between the rod-shaped bodies 100 adjacent to each other in the thickness direction. The rod-shaped bodies 100 are fitted to each other via the first concave groove 111 in the thickness direction.

いくつかの実施例において、図６ａに示すように、横方向に隣接する棒状体１００の第２の側面１２０の向きは同じである。横方向に隣接する棒状体の間にＶ字状の隙間が形成され、棒状体１００の間の接着剤の分布を容易にするのに十分な接着剤の流動空間を提供することができる。 In some embodiments, as shown in FIG. 6a, the orientation of the second side surface 120 of the laterally adjacent rods 100 is the same. A V-shaped gap is formed between the rods adjacent in the lateral direction, which can provide a sufficient flow space of the adhesive to facilitate the distribution of the adhesive among the rods 100.

他の実施例において、図６ｂに示すように、横方向に隣接する棒状体１００の第２の側面１２０の向きは反対である。即ち、横方向に隣接する棒状体１００は、交互に逆さまに配置されているため、横方向に隣接する棒状体１００の断面形状が合致し、その間に傾斜隙間が形成され、棒状体１００間は緊密に配置され、横方向に隣接する棒状体１００間の接着面積が増大する。 In another embodiment, as shown in FIG. 6b, the orientation of the second side surface 120 of the rod-shaped bodies 100 adjacent in the lateral direction is opposite. That is, since the rod-shaped bodies 100 adjacent to each other in the lateral direction are alternately arranged upside down, the cross-sectional shapes of the rod-shaped bodies 100 adjacent to each other in the lateral direction match, and an inclined gap is formed between them. It is closely arranged and the bonding area between the rod-shaped bodies 100 adjacent in the lateral direction is increased.

いくつかの実施例において、棒状体１００は、横方向に沿って平面的又は曲面的に配置されている。棒状体１００は、ブレードの輪郭に従って横方向に沿って配置される。Ｖ字状の隙間を形成する実施例では、棒状体１００を横方向に曲面状に配列する際に、横方向に隣接する棒状体１００同士なす角度をＶ字状の隙間によって調整することができ、曲面状の配列によって隙間に閉空間が形成されることがなく、閉空間による樹脂の注入不良が回避される。 In some embodiments, the rods 100 are arranged planarally or curvedly along the lateral direction. The rod-shaped body 100 is arranged along the lateral direction according to the contour of the blade. In the embodiment of forming a V-shaped gap, when the rod-shaped bodies 100 are arranged in a curved surface in the lateral direction, the angle formed by the rod-shaped bodies 100 adjacent to each other in the lateral direction can be adjusted by the V-shaped gap. , The curved arrangement does not form a closed space in the gap, and the resin injection failure due to the closed space is avoided.

いくつかの実施例において、隣接する棒状体１００の間にガイド中間層が配置され、樹脂で充填されている。ガイド中間層は、樹脂が棒状体１００の間で均一かつ良好に浸潤するのを促進し、棒状体１００の間に樹脂が浸透されないリスクを低減する。ガイド中間層は、織物シート状部材であってもよい。具体的には、ガイド中間層は２次元織物繊維布のような繊維布であり、ガイド中間層の坪量は１００～１２００ｋｇ／ｍ２であり、ガイド中間層の織り方は０°／９０°織り又は±４５°織りとすることができる。 In some embodiments, a guide intermediate layer is placed between adjacent rods 100 and filled with resin. The guide intermediate layer promotes uniform and good infiltration of the resin between the rods 100 and reduces the risk of the resin not penetrating between the rods 100. The guide intermediate layer may be a woven sheet-like member.
