Description

本発明は、例えば新幹線用車両のような高速車両に使用する繊維強化複合材製のパンタグラフカバーに関するものである。   The present invention relates to a pantograph cover made of a fiber-reinforced composite material used for a high-speed vehicle such as a Shinkansen vehicle.

従来、例えば、図９に示すように、高速車両、例えば、新幹線用車両２００には騒音防止を主目的として、パンタグラフカバー１（１Ａ、１Ｂ、１Ｃ、１Ｄ、１Ｅ）が、車体屋根２０１の上に設けられたパンタグラフ２０２の前後及び左右側面に取り付けられている。   Conventionally, for example, as shown in FIG. 9, a pantograph cover 1 (1 </ b> A, 1 </ b> B, 1 </ b> C, 1 </ b> D, 1 </ b> E) is provided on a vehicle roof 201 for the main purpose of preventing noise in a high-speed vehicle such as a Shinkansen vehicle 200. Are attached to the front and rear and the left and right sides of the pantograph 202.

つまり、パンタグラフカバー１（１Ａ、１Ｂ、１Ｃ、１Ｄ、１Ｅ）の中のパンタグラフ２０２の前後に取り付けられている先端部及び後端部カバー１Ｃ、１Ｄ、１Ｅは、パンタグラフ２０２やその下面のガイシ部２０３の風きり音を少なくするため、直接風が当たらないようにする役目をしている。   That is, the front and rear end covers 1C, 1D, and 1E attached to the front and rear of the pantograph 202 in the pantograph cover 1 (1A, 1B, 1C, 1D, and 1E) are the pantograph 202 and the bottom portion thereof. In order to reduce the wind noise of 203, it serves to prevent direct wind.

また、パンタグラフカバー１（１Ａ、１Ｂ、１Ｃ、１Ｄ、１Ｅ）の中のパンタグラフ２０２の左右側面に取り付けられているキャビティー部側壁１Ｂや、２面側壁１Ａは、発生した風きり音を横方向に伝えないような役目を目的としている。   Moreover, the cavity side wall 1B attached to the left and right side surfaces of the pantograph 202 in the pantograph cover 1 (1A, 1B, 1C, 1D, 1E) and the two-sided side wall 1A laterally generate generated wind noise. The purpose is not to tell.

斯かる従来のパンタグラフカバー１（１Ａ、１Ｂ、１Ｃ、１Ｄ、１Ｅ）は、ほとんどがアルミニウム製とされる。また、ガラス繊維強化プラスチックで検討したものもあるが、いずれにしても、最近の高速化、軽量化にとっては、問題となっている。   Most of such conventional pantograph covers 1 (1A, 1B, 1C, 1D, 1E) are made of aluminum. Although some have been studied for glass fiber reinforced plastics, anyway, it is a problem for recent high speed and light weight.

つまり、車両高速化のニーズの高まりから、高速化に伴う軌道等のインフラへの影響を緩和させるため、車両の軽量化が大きな課題となっている。そのため、使用材料も金属から比重の小さい繊維強化樹脂（複合材）への転換が期待されている。   In other words, from the increasing needs for speeding up vehicles, reducing the weight of vehicles has become a major issue in order to mitigate the impact on the infrastructure such as the track associated with speeding up. Therefore, the use material is expected to be changed from metal to fiber reinforced resin (composite) having a small specific gravity.

最初は、ガラス繊維強化プラスチックが模索されたが、強度、剛性の面から軽量化の設計ができなく、また直近のリサイクルの問題もあり、他の材料の進出が期待されていた。
特開平６−２１７４０５号公報 特開２００３−２１９５０５号公報 At first, glass fiber reinforced plastic was sought, but because of its strength and rigidity, it was not possible to design a lighter weight, and due to the recent problems of recycling, other materials were expected to advance.
JP-A-6-217405 JP 2003-219505 A

そこで、本発明の目的は、軽量化を達成し、また、強度、剛性の面でも満足し得る設計が可能であって、高速車両に使用することのできる繊維強化複合材製のパンタグラフカバーを提供することである。   Accordingly, an object of the present invention is to provide a pantograph cover made of a fiber reinforced composite material that can achieve a weight reduction and can be designed with satisfactory strength and rigidity, and can be used for a high-speed vehicle. It is to be.

The upper surface panel 1D and the side wall panel 1E do not have to be realized, and can be applied to a plurality of arbitrary members.

（２面側壁の構成）
次に、本実施例にて、繊維強化複合材にて作製されるパンタグラフカバー１（１Ａ、１Ｂ、１Ｃ、１Ｄ、１Ｅ）の中の２面側壁１Ａについて説明する。 (Structure of two side walls)
Next, in this embodiment, a description will be given of the two-side wall 1A in the pantograph cover 1 (1A, 1B, 1C, 1D, 1E) made of a fiber reinforced composite material.

図２（ａ）は、２面側壁１Ａの概略全体構成を示す。また、図３は、図２（ａ）の線III−IIIに取った断面図であり、２面側壁１Ａを作製する繊維強化複合材の一実施例を示す。ただ、図３では、２面側壁１Ａを作製する繊維強化複合材は、図９に示すような２面側壁１Ａの使用時の状態とは異なり、水平に置かれた状態で図示されている。   FIG. 2A shows a schematic overall configuration of the two-sided sidewall 1A. FIG. 3 is a cross-sectional view taken along line III-III in FIG. 2A, showing an embodiment of the fiber-reinforced composite material for producing the two-sided sidewall 1A. However, in FIG. 3, the fiber reinforced composite material for producing the two-sided sidewall 1A is shown in a horizontally placed state, unlike the state when the two-sided sidewall 1A is used as shown in FIG.

図２、図３に示す本実施例にて、２面側壁としての繊維強化複合材製パンタグラフカバー１Ａは、板状のメイン部材２にて構成される。本実施例にて、板状のメイン部材２は、図２（ａ）に示すように、略台形状とされる。   In the present embodiment shown in FIGS. 2 and 3, a fiber-reinforced composite material pantograph cover 1 </ b> A as a two-side wall is constituted by a plate-like main member 2. In the present embodiment, the plate-like main member 2 has a substantially trapezoidal shape as shown in FIG.

図３にて、メイン部材２は、内層のハニカム構造体４と、ハニカム構造体４の周囲端面に形成された補強部５と、ハニカム構造体４及び補強部５の上下外表面を被覆して接着配置された表面層としての繊維強化複合材１１（１１ａ、１１ｂ）とにて形成される。補強部５は、本実施例では、台形状とされるメイン部材２の底辺部２ａを除いて、残りの周囲端面２ｂ、２ｃ、２ｄに所定の幅（ｗ）にて形成されている。勿論、必要に応じて底辺部２ａにも設けることができる。   In FIG. 3, the main member 2 covers the inner layer honeycomb structure 4, the reinforcing portion 5 formed on the peripheral end surface of the honeycomb structure 4, and the upper and lower outer surfaces of the honeycomb structure 4 and the reinforcing portion 5. It is formed with the fiber reinforced composite material 11 (11a, 11b) as a surface layer that is bonded and arranged. In this embodiment, the reinforcing portion 5 is formed on the remaining peripheral end surfaces 2b, 2c, and 2d with a predetermined width (w) except for the base portion 2a of the main member 2 having a trapezoidal shape. Of course, it can also be provided on the bottom 2a as required.

つまり、補強部５は、内層のハニカム構造体４の周囲端面の一部若しくは全部において所定の幅（ｗ）にて形成される。この幅（ｗ）は、後述するが、通常、１０ｍｍ〜５０ｍｍの範囲とされる。   That is, the reinforcing portion 5 is formed with a predetermined width (w) in a part or all of the peripheral end surface of the honeycomb structure 4 as the inner layer. Although this width | variety (w) is mentioned later, it is normally made into the range of 10 mm-50 mm.

このように、本実施例の２面側壁として使用する繊維強化複合材製パンタグラフカバー１Ａは、内層のハニカム構造体４の外周囲端面の一部若しくは全部を所定の幅（ｗ）にて形成された補強部５で補強し、その両表面に繊維強化複合材１１（１１ａ、１１ｂ）を接着することで得られる。   Thus, the pantograph cover 1A made of fiber reinforced composite material used as the two-side wall of the present embodiment is formed with a predetermined width (w) at a part or all of the outer peripheral end face of the honeycomb structure 4 of the inner layer. It is obtained by reinforcing with the reinforcing portion 5 and adhering the fiber reinforced composite material 11 (11a, 11b) to both surfaces thereof.

上記構成の本実施例の繊維強化複合材製パンタグラフカバー１Ａによれば、内層にハニカム構造体４を配置することで、中空の場合に比較して、曲げ強度、弾性率とも向上する。又、繊維強化複合材製パンタグラフカバー１Ａは、補強部５の領域を利用して所定の形状に容易に切断することができる。   According to the pantograph cover 1A made of the fiber reinforced composite material of the present embodiment having the above-described configuration, the bending strength and the elastic modulus are improved by disposing the honeycomb structure 4 in the inner layer as compared with the hollow case. Further, the pantograph cover 1A made of fiber reinforced composite material can be easily cut into a predetermined shape using the region of the reinforcing portion 5.

次に、本実施例の繊維強化複合材製パンタグラフカバー１Ａの各部材について更に詳しく説明する。   Next, each member of the pantograph cover 1A made of fiber reinforced composite material of the present embodiment will be described in more detail.

（繊維強化複合材）
本実施例の繊維強化複合材製パンタグラフカバー１Ａにて、繊維強化複合材１１に使用される強化繊維としては、炭素繊維、ガラス繊維、アラミド繊維、又は、ＰＢＯ（ポリパラフェニレンベンズビスオキサゾール）繊維のいずれかを単独で、又は、複数種混入してハイブリッドにて使用することができる。 (Fiber reinforced composite material)
In the pantograph cover 1A made of the fiber reinforced composite material of the present embodiment, carbon fiber, glass fiber, aramid fiber, or PBO (polyparaphenylene benzbisoxazole) fiber can be used as the fiber reinforced composite material 11. Any of these may be used alone or in a hybrid mixed with a plurality of types.

また、繊維強化複合材１１に使用される繊維の形態は、一方向に引き揃えられたＵＤ形状、２軸に織られた平織り及び朱子織り形状、又は、３軸に織られた３軸織り形状が単独で、又は、複数組み合わされて使用することができる。   Further, the form of the fiber used for the fiber reinforced composite material 11 is a UD shape aligned in one direction, a plain weave and satin weave shape woven in two axes, or a triaxial weave shape woven in three axes. Can be used alone or in combination.

また、繊維強化複合材１１に使用されるマトリックス樹脂は、エポキシ樹脂、不飽和ポリエステル樹脂、ビニールエステル樹脂、ＭＭＡ樹脂、又は、フェノール樹脂のいずれかが使用できる。   Moreover, the matrix resin used for the fiber reinforced composite material 11 can be any of epoxy resin, unsaturated polyester resin, vinyl ester resin, MMA resin, or phenol resin.

繊維強化複合材１１の繊維体積含有率は、３０〜７０％、通常、５０〜６０％とされる。   The fiber volume content of the fiber reinforced composite material 11 is 30 to 70%, usually 50 to 60%.

（内層及び補強部）
本実施例にて、メイン部材２のハニカム構造体４としては、例えば、通常使用されるアルミニウム、アラミド樹脂、或いは紙などで作製したハニカムが使用可能であり、特に、ノーメックスハニカム（商品名：ディーアイシーヘクセル株式会社製）を好適に使用することができる。 (Inner layer and reinforcement)
In the present embodiment, as the honeycomb structure 4 of the main member 2, for example, a honeycomb made of usually used aluminum, aramid resin, or paper can be used. Icy Hexel Co., Ltd.) can be preferably used.

メイン部材２の補強部５は、一実施態様によれば、図１及び図２（ａ）に示すように、ハニカム構造体４の端面の開放部、即ち、孔部４ａに軽量樹脂Ｒを充填、即ち、詰め込むことによって形成される。   According to one embodiment, the reinforcing part 5 of the main member 2 is filled with a lightweight resin R in the open part of the end face of the honeycomb structure 4, that is, the hole part 4a, as shown in FIG. 1 and FIG. That is, it is formed by stuffing.

また、補強部５の幅（ｗ）は、上述のように、１０ｍｍ〜５０ｍｍの範囲とされるが、本発明者らの研究実験の結果によれば、１０ｍｍ未満だと、繰り返し荷重がかかった際、強度低下が早期に起こったことから、１０ｍｍ以上は必須であり、上限は重量面から、５０ｍｍ以下が妥当である。   In addition, the width (w) of the reinforcing portion 5 is in the range of 10 mm to 50 mm as described above. However, according to the results of the research experiment by the present inventors, a load was repeatedly applied when the width was less than 10 mm. At this time, since the strength drop occurred early, 10 mm or more is essential, and the upper limit is 50 mm or less in terms of weight.

上述のように、補強部５は、ハニカム構造体４の端部に、端面よりｗ＝１０ｍｍ〜５０ｍｍの範囲の領域に、補強材として、軽量樹脂Ｒを、ハニカム構造体４内に詰め込むことによって、ハニカム構造体４の周囲を補強する。   As described above, the reinforcing portion 5 is formed by packing the lightweight resin R as a reinforcing material in the honeycomb structure 4 in the end portion of the honeycomb structure 4 in a range of w = 10 mm to 50 mm from the end face. The periphery of the honeycomb structure 4 is reinforced.

ハニカム構造体４の周囲に詰め込む軽量樹脂Ｒは、エポキシ樹脂、不飽和ポリエステル樹脂、ビニールエステル樹脂、ＭＭＡ樹脂、ウレタン樹脂のいずれかが好適である。更に、軽量樹脂Ｒとしては、上記樹脂に、強化材を混入したものも使用できる。具体的には、炭素繊維の短繊維、ガラス繊維の短繊維、カーボンブラック、炭酸カルシウム、水酸化アルミニウム、ガラスバルーン、エポキシ発泡バルーン、ウレタン発泡バルーン、アクリル発泡バルーンのいずれか１種又は複数種を強化材として、エポキシ樹脂、不飽和ポリエステル樹脂、ビニールエステル樹脂、ＭＭＡ樹脂、又はウレタン樹脂のいずれかに混入したものを軽量樹脂Ｒとして使用することができる。   The lightweight resin R packed around the honeycomb structure 4 is preferably an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, an MMA resin, or a urethane resin. Further, as the lightweight resin R, a resin in which a reinforcing material is mixed into the resin can be used. Specifically, one or more of carbon fiber short fiber, glass fiber short fiber, carbon black, calcium carbonate, aluminum hydroxide, glass balloon, epoxy foam balloon, urethane foam balloon, and acrylic foam balloon are used. As a reinforcing material, an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, an MMA resin, or a urethane resin can be used as the lightweight resin R.

上記実施例では、補強部５は、図３に示すように、ハニカム構造体４の外周囲において、ハニカム構造体４の端面開放部、即ち、孔部４ａに軽量樹脂Ｒを詰め込むことによって形成されるものとして説明したが、他の実施態様によれば、図４に示すように、ハニカム構造体４の周囲端面４ｂに隣接した外側の一部若しくは全部に、幅１０ｍｍ〜５０ｍｍの範囲で軽量樹脂Ｒを配置して、補強部５を形成することもできる。   In the above embodiment, as shown in FIG. 3, the reinforcing portion 5 is formed by filling the end face opening portion of the honeycomb structure 4, that is, the hole portion 4 a with the lightweight resin R around the outer periphery of the honeycomb structure 4. However, according to another embodiment, as shown in FIG. 4, a lightweight resin having a width in the range of 10 mm to 50 mm is provided on a part or all of the outer side adjacent to the peripheral end surface 4 b of the honeycomb structure 4. R can also be arrange | positioned and the reinforcement part 5 can also be formed.

本実施例によれば、メイン部材２を構成するハニカム構造体４とされる内層の端部に、軽量樹脂Ｒからなる補強部５を設けることによって、ハニカム構造体４の端部の弱さを補強し、曲げ強度、疲労強度に強い繊維強化複合材製パンタグラフカバー１Ａを提供することができる。   According to the present embodiment, by providing the reinforcing portion 5 made of the lightweight resin R at the end portion of the inner layer which is the honeycomb structure 4 constituting the main member 2, the weakness of the end portion of the honeycomb structure 4 is reduced. A pantograph cover 1A made of a fiber reinforced composite material that is reinforced and has high bending strength and fatigue strength can be provided.

更に、図２（ｂ）に示すように、必要に応じて、パンタグラフカバー１Ａの上面端縁部には、半円状の繊維強化複合材２０を一体に形成することができる。   Furthermore, as shown in FIG. 2B, a semicircular fiber-reinforced composite material 20 can be integrally formed on the upper edge portion of the pantograph cover 1A as necessary.

つまり、パンタグラフカバー１Ａが車体屋根２０１に取り付けられた時、車体屋根２０１より外部に露出するメイン部材２の端縁部２ｂ、２ｃ、２ｄに沿って、上面部に軽量樹脂Ｒで形成した半円状の部材２２を配置し、該半円状部材２２の表層に繊維強化複合材２１を積層することができる。繊維強化複合材２１は、上記繊維強化複合材１１（１１ａ、１１ｂ）と同じ構成とし得る。   In other words, when the pantograph cover 1A is attached to the vehicle roof 201, a semicircle formed of a lightweight resin R on the upper surface along the edge portions 2b, 2c, 2d of the main member 2 exposed to the outside from the vehicle roof 201. The fiber-reinforced composite material 21 can be laminated on the surface layer of the semicircular member 22. The fiber reinforced composite material 21 may have the same configuration as the fiber reinforced composite material 11 (11a, 11b).

（具体的寸法例）
上記構成の本実施例による繊維強化複合材製パンタグラフカバー１の具体的な諸寸法の一例を挙げれば、次の通りである。図２を参照して、
（１）パンタグラフカバー１Ａの長辺部２ａの長さ（Ｌ１）：５１３４ｍｍ
（２）パンタグラフカバー１Ａの短辺部２ｃの長さ（Ｌ２）：１６２０ｍｍ

ここで、板状メイン部材２の厚さ（Ｔ１）は５０ｍｍ、内層（ハニカム構造体）４の厚さ（Ｔ２）は４６ｍｍ、表面層（繊維強化複合材）１１の厚さ（Ｔ３）は２ｍｍとすることができる。又、補強部の幅ｗは２７ｍｍとした。 (Specific dimension example)
An example of specific dimensions of the pantograph cover 1 made of fiber-reinforced composite material according to the present embodiment having the above-described configuration is as follows. With reference to FIG.
(1) Length (L1) of the long side portion 2a of the pantograph cover 1A: 5134 mm
(2) Length of short side 2c of pantograph cover 1A (L2): 1620 mm
(3) Height of pantograph cover 1A (H): 1000 mm
Here, the thickness (T1) of the plate-like main member 2 is 50 mm, the thickness (T2) of the inner layer (honeycomb structure) 4 is 46 mm, and the thickness (T3) of the surface layer (fiber reinforced composite material) 11 is 2 mm. It can be. The width w of the reinforcing portion was 27 mm.

尚、上記実施例では、内層としては、ハニカム構造体４が配置されたものとして説明したが、内層として、ハニカム構造体４と繊維強化複合材１２とが交互に２層以上積層された積層構造体とすることも可能である。本実施例では、図５に示すように、ハニカム構造体４Ａ、繊維強化複合材１２、ハニカム構造体４Ｂから成る３層構造とされるが、これに限定されるものではない。   In the above-described embodiment, the inner layer is described as having the honeycomb structure 4 disposed therein. However, as the inner layer, a laminated structure in which the honeycomb structure 4 and the fiber reinforced composite material 12 are alternately laminated. It can also be a body. In this embodiment, as shown in FIG. 5, a three-layer structure including a honeycomb structure 4A, a fiber reinforced composite material 12, and a honeycomb structure 4B is used, but the present invention is not limited to this.

内層を構成する繊維強化複合材１２は、表面層として使用する繊維強化複合材１１（１１ａ、１１ｂ）と同じものを使用し得る。   As the fiber reinforced composite material 12 constituting the inner layer, the same fiber reinforced composite material 11 (11a, 11b) used as the surface layer can be used.

又、補強部５（５Ａ、５Ｂ）は、上述と同様に、各ハニカム構造体４の周囲端面４ｂに隣接した外側の一部若しくは全部に、幅１０ｍｍ〜５０ｍｍの範囲で軽量樹脂Ｒを配置して、或いは、ハニカム構造体４の孔部４ａに軽量樹脂Ｒを充填することができる。   In addition, in the reinforcing portion 5 (5A, 5B), the light weight resin R is disposed in a width of 10 mm to 50 mm on a part or all of the outside adjacent to the peripheral end surface 4b of each honeycomb structure 4 in the same manner as described above. Alternatively, the lightweight resin R can be filled in the holes 4 a of the honeycomb structure 4.

（パンタグラフカバーの製造方法）
先ず、本実施例の繊維強化複合材製パンタグラフカバー１Ａを製造するに際しては、周囲を端面補強された補強部５を有するハニカム構造体とされる内層４の上下両表面に、繊維強化複合材１１（１１ａ、１１ｂ）を接着、硬化する。必要に応じて、ハニカム構造体４は、図５に示すように、繊維強化複合材１２を介して積層して内層を形成し、この内層４の上下両表面に、繊維強化複合材１１（１１ａ、１１ｂ）を接着、硬化することもできる。 (Pantograph cover manufacturing method)
First, when manufacturing the pantograph cover 1A made of the fiber reinforced composite material of the present embodiment, the fiber reinforced composite material 11 is formed on both upper and lower surfaces of the inner layer 4 which is a honeycomb structure having the reinforcing portion 5 whose end face is reinforced. (11a, 11b) is bonded and cured. As shown in FIG. 5, the honeycomb structure 4 is laminated with a fiber reinforced composite material 12 to form an inner layer, and the fiber reinforced composite material 11 (11a) is formed on both upper and lower surfaces of the inner layer 4, as shown in FIG. 11b) can also be bonded and cured.

その後、補強部５を利用して所定の寸法に切断、加工することにより、本実施例の繊維強化複合材製パンタグラフカバー１Ａが提供される。   Then, the pantograph cover 1A made of a fiber reinforced composite material according to the present embodiment is provided by cutting and processing the reinforcing part 5 into a predetermined size.

本実施例のパンタグラフカバー１Ａは、図３にて、下表面層としての繊維強化複合材１１ｂの上に、周囲を端面補強されたハニカム構造体４を乗せ、さらに、ハニカム構造体４の上表面に上表面層としての繊維強化複合材１１ａを乗せて、これら部材を互いに接着することで製作される。   The pantograph cover 1A of the present example is obtained by placing the honeycomb structure 4 whose end face is reinforced on the fiber reinforced composite material 11b as the lower surface layer in FIG. A fiber reinforced composite material 11a as an upper surface layer is placed on the upper surface layer and these members are bonded to each other.

従って、成形が非常に簡単であり、また最初から全体を大きめに製作し、後で正確な寸法に切断、加工することができるメリットもある。   Therefore, there is an advantage that molding is very simple, and the whole can be made larger from the beginning, and can be cut and processed to an accurate dimension later.

つまり、最初から周囲の端部補強部５を、その加工代を予測して大きくしておけば、加工時にハニカム構造体４が端面に出てくる心配はない。   That is, if the peripheral end reinforcing portion 5 is enlarged from the beginning by predicting the machining allowance, there is no fear that the honeycomb structure 4 comes out on the end face during the machining.

また、成形の時の寸法精度が、それ程よくなくても、後加工で処理できることから、この面からも成形が楽になり、安価なコストでの成形が可能となる。   In addition, even if the dimensional accuracy at the time of molding is not so good, it can be processed by post-processing, so that molding can be facilitated from this surface, and molding can be performed at low cost.

更に、上下層に配置される繊維強化複合材１１（１１ａ、１１ｂ）に使用する繊維を選択することで、高強度の繊維強化複合材製パンタグラフカバー１Ａ、高剛性の繊維強化複合材製パンタグラフカバー１Ａ、電気絶縁性をもった繊維強化複合材製パンタグラフカバー１Ａ等の設計、製作が容易にできる利点もある。   Further, by selecting fibers to be used for the fiber reinforced composite material 11 (11a, 11b) disposed in the upper and lower layers, a high strength fiber reinforced composite material pantograph cover 1A, a high rigidity fiber reinforced composite material pantograph cover 1A, there is also an advantage that the design and manufacture of the pantograph cover 1A made of fiber reinforced composite material having electrical insulation can be easily performed.

例えば、繊維強化複合材１１の強化繊維として、高強度炭素繊維Ｔ−７００（東レ株式会社製）を採用すると、アルミと同じ厚みで、アルミ製の３倍以上の強度が得られ、高弾性率炭素繊維ＸＮ−６０（日本グラファイトファイバー株式会社製）を採用すると、アルミと同じ厚みで、アルミ製の２倍以上の曲げ剛性が得られる。   For example, when a high-strength carbon fiber T-700 (manufactured by Toray Industries, Inc.) is used as the reinforcing fiber of the fiber-reinforced composite material 11, the same thickness as that of aluminum can be obtained, and a strength three times that of aluminum can be obtained. When carbon fiber XN-60 (manufactured by Nippon Graphite Fiber Co., Ltd.) is employed, a bending rigidity twice or more that of aluminum can be obtained with the same thickness as aluminum.

また、高強度炭素繊維と高弾性率炭素繊維を組み合わせて採用すると、強度、弾性率両方を満足したものが得られる。一方、ＰＢＯ繊維を採用すると、アルミと同じ厚みで、アルミ製並みの曲げ剛性を持ち、且つ電気絶縁性をもったものが得られる。   Further, when a combination of high-strength carbon fiber and high-modulus carbon fiber is employed, a fiber satisfying both strength and elastic modulus can be obtained. On the other hand, when PBO fiber is used, a fiber having the same thickness as aluminum, bending rigidity comparable to that of aluminum, and electrical insulation can be obtained.

本実施例によれば、パンタグラフカバー１の曲げ強度や曲げ弾性率が大幅に向上するのみでなく、端面の応力集中に対しても補強され、曲げ疲労に対しても強いものとなる。   According to the present embodiment, not only the bending strength and the bending elastic modulus of the pantograph cover 1 are significantly improved, but also it is reinforced against stress concentration at the end face and is resistant to bending fatigue.

It is set as the laminated structure which has the fiber reinforced composite material 11a and 11b which form the both-sides surface layer of 4. As shown in FIG.
