It is used in fields where lightness is required, such as in aircraft.
従来は、航空機等の軽さを要求される分野における構造

ル形状の構造のものであって、その多腔性構造の各室内
は空気で満たされているものであった。Traditionally, structural members used in fields that require light weight, such as aircraft, have a honeycomb structure or a corrugated cardboard-shaped structure with corrugated plates sandwiched between flat plates, and each chamber of the multi-chamber structure is filled with air. It was something that had been done.

問題点を解決し、従来の構造用部材より軽い構造用部材
を得ることを目的とする。The present invention solves the problem that conventional honeycomb structure or corrugated cardboard-shaped multi-chamber structural members have a limit because if the thickness of the structural member is made thinner or the voids are made larger in order to make it lighter, the strength decreases. There was a point. The present invention aims to solve the above-mentioned problems and to obtain a structural member that is lighter than conventional structural members.
上記問題点を解決し、本発明の目的を達成するため、本
発明に係わる軽気体封入構造用部材は、空気より比重の
軽い気体を多腔性構造の各室内に封入してなることを特
徴とする。In order to solve the above-mentioned problems and achieve the object of the present invention, the light gas-filled structure member according to the present invention is characterized in that a gas having a specific gravity lower than that of air is sealed in each chamber of a multi-chamber structure. shall be.
ここで、空気より比重の軽い気体とは、空気の平均分子
量が28.8であるので、ヘリウム(4)、水素(2)
及び窒素(28)等を挙げることができる。これを減圧
して封入すればさらに比重を小さくすることができる。Here, gases with a specific gravity lighter than air include helium (4), hydrogen (2), since the average molecular weight of air is 28.8.
and nitrogen (28). If this is sealed under reduced pressure, the specific gravity can be further reduced.
しかし、この中で最も効果が大きくまた安全であるもの
を挙げれば、それはヘリウムである。この構造材に封入
する空気より比重の小さい気体は大気と同じ圧力でもよ
いし、航空機は通常高度の高い所を飛ぶためにその外気
にあわせて減圧して封入してもよい。However, the most effective and safest of these is helium. The gas with a specific gravity lower than air sealed in this structural material may be at the same pressure as the atmosphere, or may be sealed at a reduced pressure to match the outside air since aircraft usually fly at high altitudes.
多腔性構造としては、ハニカム構造や段ボール形状の構

気密性が保たれかつ良好な剥離強度を有し、軽量なもの
を用いると効果的である。To enclose a light gas in each small pore of a structural member, thin plates or film sheets are attached to the ends of the honeycomb structure by gluing or welding in an environment such as atmospheric pressure or reduced pressure of helium gas. Alternatively, after gluing or welding the thin plates or film sheets in air, make a small hole through the outer shell in each cavity and let the air inside through the hole. Alternatively, a gas such as helium gas which has been removed and has a reduced pressure may be sealed. Adhesives include epoxy resin adhesives, resin films made of nylon and epoxy, or neoprene adhesives that maintain airtightness even under low or high temperatures and high pressure, have good peel strength, and are lightweight. It is effective to use

これらと接着性の良い材質を用いると良い。In addition, the outer panels and side panels attached to the ends of the honeycomb structure or corrugated structure are made of materials such as aluminum, titanium alloy, polyvinyl fluoride, nylon, or polyvinyl chloride, which are lightweight and do not easily allow the enclosed gas to pass through. , FR reinforced with glass fiber, PAN fiber, carbon fiber, etc.
It is effective to use a P plate (fiber-reinforced plastics) or the like, and the honeycomb core material and corrugated plate are preferably made of the same material as the outer panel and side panels, or a material that has good adhesion to these.
〔作用]
従来は、軽さを要求される構造用部材は六角形のハニカ
ムからなるハニカム材や波板を平板ではさんだ段ボール
材等を用い、その空隙部は空気であった。[Function] Conventionally, structural members that are required to be lightweight are made of a honeycomb material made of hexagonal honeycombs, a corrugated cardboard material made of corrugated plates sandwiched between flat plates, etc., and the voids thereof are filled with air.
構造材の強度をある必要な程度とするためにはその構造
材が同一であるかぎりは一定の重量の構造材とならざる
をえないが、この発明のようにハニカム構造体や段ボー
ル形状体の空隙部に、空気より比重の小さいヘリウム等
の気体を封入することによりさらに剛気体の比重差分の
重量を軽減することができる。In order to achieve the required strength of a structural material, the structural material must have a constant weight as long as the structural material is the same. By filling the void with a gas such as helium, which has a lower specific gravity than air, it is possible to further reduce the weight due to the difference in specific gravity of the rigid gas.
この構造材に封入する空気より比重の小さい気体は大気
と同じ圧力でもよいし、航空機は通常高度の高い所を飛
ぶためにその外気にあわせて減圧して封入してもよい。The gas with a specific gravity lower than air sealed in this structural material may be at the same pressure as the atmosphere, or may be sealed at a reduced pressure to match the outside air since aircraft usually fly at high altitudes.
この空気より比重の小さい気体を構造材に封入するにあ

しており、一部が損傷したからといって他の部分までの
封入気体が外に漏れたりするような影響がないので、安
全性を損ねることはない。In order to seal this gas, which has a lower specific gravity than air, into the structural material, it is sufficient to use an adhesive with good airtightness when bonding the outer panel to the core material, but many voids in honeycomb structures and corrugated cardboard structures are adjacent to each other. Since the sealed gas exists in the air, it is difficult for the sealed gas to escape to the outside (and when the gas inside is sealed after being reduced in pressure, it is difficult for air to enter from the outside.The structure of this invention is used for structural materials of aircraft, etc.) In such a case, even if a part of the structure is damaged, there are many voids in the honeycomb structure or cardboard shape that are sealed independently, so it is not possible to damage a part of the structure. However, there is no risk of the sealed gas leaking out to other parts, so safety will not be compromised.
