The substantially hourglass-shaped gap also makes the resin flow more smoothly, improves the injection efficiency and injection quality, and avoids the occurrence of defects such as cavities, bubbles, etc. between the rods.

いくつかの実施例において、図２及び図３を引き続き参照すると、隣接する棒状体群１０ａにおける横方向Ｘに隣接する棒状体１００同士は対応して配置されている。好ましい実施例では、隣接する棒状体群１０ａの間の棒状体１００は、縦方向Ｙにおいてそろっている。このように、複数の棒状体１００を梁状に配列する際に、棒状体１００の縦方向Ｙの位置を調整するための突起又はスペーサを別途に設けることなく、棒状体１００を平坦な表面上に配置することができる。さらに、棒状体群１０ａ内の棒状体１００は、横方向Ｘに整列して配置されている。このように複数の棒状体１００を梁状に配列する際に、棒状体１００を縦方向Ｙに簡単に積層することができ、生産効率を向上させることができる。当然のことながら、棒状体１００は、積層して配置する際に、操作誤差のために位置のわずかなずれが生じてしまい、棒状体１００は、一定の許容誤差の範囲内で実質的にはそろっている。 In some embodiments, with continued reference to FIGS. 2 and 3, laterally adjacent rods 100 in adjacent rod groups 10a are arranged correspondingly. In a preferred embodiment, the rods 100 between adjacent rod groups 10a are aligned in the longitudinal direction Y. As shown in FIG.

図４を併せて参照すると、本願の第１の実施例による梁における棒状体の断面構造の概略図が示されている。 Also referring to FIG. 4, there is shown a schematic diagram of the cross-sectional structure of the bar in the beam according to the first embodiment of the present application.

いくつかの実施例において、図４を引き続き参照すると、棒状体１００の第１の側面１１０及び第２の側面１２０は、第１の曲面１３０及び第２の曲面１４０と共に棒状体１００の断面を画定し、第１の曲面１３０と第２の曲面１４０の対応横断面の輪郭線は、それぞれ連続曲線となっている。第１の曲面１３０及び第２の曲面１４０は、幅方向及び厚み方向に湾曲した曲面である。樹脂を充填する際には、連続曲線により樹脂の流れがさらにスムーズになり、樹脂充填効率を向上させ、樹脂と棒状体１００との間に良好な接合が形成される。また、曲面は、例えばブレードの外皮形状により適合させ、外皮との間の隙間をより小さくし、外皮との間の樹脂使用量を低減することができる。 In some embodiments, with continued reference to FIG. 4, first side 110 and second side 120 of rod 100 together with first curved surface 130 and second curved surface 140 define a cross-section of rod 100. The contour lines of corresponding cross sections of the first curved surface 130 and the second curved surface 140 are continuous curves. The first curved surface 130 and the second curved surface 140 are curved surfaces curved in the width direction and the thickness direction. When the resin is filled, the continuous curve makes the resin flow more smoothly, improves the resin filling efficiency, and forms a good bond between the resin and the bar 100 . Also, the curved surface can, for example, better conform to the skin shape of the blade, allowing for a smaller clearance between the skin and a reduced amount of resin used between the skin.

いくつかの実施例において、図４を引き続き参照すると、棒状体１００の断面は、中心対称図形である。このような棒状体１００は、梁に積層される際に、縦方向Ｙに沿って棒状体１００を順方向及び逆方向の何れかでも配置し、他の棒状体１００との相互係合に影響を与えることなく、棒状体１００を積層する工程の効率を向上させ、時間と人件費を削減することができる。他の選択可能な実施例において、棒状体１００の断面は、鏡像対称パターンであってもよく、曲面を設けることができ、かつ隣接する棒状体１００の曲面が嵌合又は当接することができればよい。 In some embodiments, with continued reference to FIG. 4, the cross-section of bar 100 is a centrosymmetric figure. Such rods 100, when stacked on a beam, can position the rods 100 either forwards or backwards along the longitudinal direction Y, affecting interengagement with other rods 100. , the efficiency of the process of stacking the rods 100 can be improved, and time and labor costs can be reduced. In other alternative embodiments, the cross-section of the bar 100 may be a mirror symmetrical pattern, may have curved surfaces, and the curved surfaces of adjacent bar 100 may fit or abut. .

Furthermore, the second curved surface 140 of the rod-shaped body 100 has a protruding end in the width direction, and the protruding end is adjacent to the second side surface 120 in the thickness direction. The cross section of the bar-shaped body 100 is substantially parallelogram-shaped. Since the extending direction of the gap between the rod-shaped bodies 100 adjacent to each other in the horizontal direction X is inclined with respect to the horizontal direction X in this way, the bonding area between the resin and the rod-shaped bodies 100 is increased, and the bonding strength is increased. to increase the strength of the beam.

いくつかの実施例において、図４を引き続き参照すると、棒状体１００の第１の側面１１０及び第２の側面１２０は、第１の曲面１３０及び第２の曲面１４０の両方と鈍角で交差する。鋭角構造に起因する応力集中や鋭角構造が荷重を受けた際に発生しやすいクラックを回避して、棒状体１００及び梁の強度を向上させることができる。また、第１の側面１１０及び第２の曲面１４０、又は第２の側面１２０及び第１の曲面１３０上に、離型布又は、棒状体１００の表面を粗面化する他の剥離層を配置することがより容易であり、離型布や他の剥離層の除去が困難になることを回避することができる。 In some embodiments, with continued reference to FIG. 4, first side 110 and second side 120 of bar 100 intersect both first curved surface 130 and second curved surface 140 at an obtuse angle. The strength of the rod-shaped body 100 and the beam can be improved by avoiding stress concentration due to the acute-angled structure and cracks that are likely to occur when the acute-angled structure receives a load. Also, a release cloth or other release layer for roughening the surface of the rod-shaped body 100 is arranged on the first side surface 110 and the second curved surface 140 or the second side surface 120 and the first curved surface 130. is easier to apply, and difficult removal of release cloths and other release layers can be avoided.

The guide intermediate layer promotes uniform and good infiltration of the resin between the rod-shaped bodies 100 and can reduce the risk of the resin not permeating between the rod-shaped bodies 100 . The guide intermediate layer may be a woven sheet-like member. Specifically, the guide intermediate layer is a two-dimensional woven fiber cloth, the basis weight of the guide intermediate layer is 100-1200 kg/m 2 , and the weave of the guide intermediate layer is 0°/90° weave or ±45° Can be woven.
