【発明の詳細な説明】
（イ） 産業上の利用分野
本発明は、防振、制振、防行等に優れた効果を示す強度
的にも優れた複合防振材料に関するものである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a composite vibration-proofing material that exhibits excellent vibration-proofing, vibration-damping, road-proofing, etc. effects and is also excellent in strength.
（ロ）従来技術とその間鴨点
従来、産’Ｊ ４賊、内燃機関、自動車、電車等の引き
起す振動や騒音を吸収するため、ゴム製の防振パッドや
防振シートが多く使用されているが、ゴムのみから成る
防振材は、剛性が低いため、大きな荷重が加えられたり
、小さな荷重であっても長時間継続して加えられたりす
ると、永久変形し、防振を目的とした構造物や機賊類の
位置ずれを生じる欠点がある。(b) Conventional technology and its history Conventionally, rubber anti-vibration pads and anti-vibration sheets have been widely used to absorb vibrations and noise caused by industrial vehicles, internal combustion engines, automobiles, trains, etc. However, vibration isolators made only of rubber have low rigidity, so if a large load is applied, or even a small load is continuously applied for a long period of time, it will permanently deform, making it difficult to use for vibration isolation purposes. It has the disadvantage of causing the positions of structures and pirates to shift.
また、ゴムは剛性のある材料に比較して弾性回復力が弱
いため、低周波成分の振動しか吸収できないと云う振動
吸収能の面でも抜本的に解決すべき問題点を有している
。Furthermore, since rubber has a weak elastic recovery force compared to rigid materials, it has a problem in terms of vibration absorption ability that must be fundamentally solved in that it can only absorb vibrations of low frequency components.
（ハ） 間額点を解決すぎための手段
そこで、本発明は、連通性多孔質金属の空孔に、例えば
ポリウレタンゴム、エチレン−酢酸ビニル共重合体、塩
ビー酸酸ビニール共屯合体等のエラストマーを充填する
ことによって防振材の剛性不足の間頃を解消したもので
ある。(c) Means for solving the problem too much In the present invention, for example, polyurethane rubber, ethylene-vinyl acetate copolymer, vinyl chloride acid copolymer, etc. By filling it with elastomer, the lack of rigidity of the vibration isolating material was solved.
即ち、上記の構成とした防振材料は、多孔質金属が剛性
面での補強材となり、しかも、その空孔に充填されたエ
ラストマーは空孔が連通しているため全体に連続してお
り、従ってエラストマーのもつ低周波振動吸収能を殺す
ことなく強度を向上させることができる。That is, in the vibration damping material having the above structure, the porous metal serves as a reinforcing material in terms of rigidity, and the elastomer filled in the pores is continuous throughout because the pores are connected. Therefore, the strength can be improved without destroying the low frequency vibration absorbing ability of the elastomer.
また、多孔質金属の材料としてＭ、 、 Ａｌ 、 ｚ
ｎ 。In addition, M, , Al, z are used as porous metal materials.

すＮｉ −Ｔｉ 合金等を使用すれば、多孔質金属が一
層高周波振動の吸収効果を発揮するので、広範な周波数
帯域の振動を吸収、減衰させることができる。Copper alloy containing at least 15 to 60% by weight of elemental Ni, or 1% or more of each of these metals, in total at least 15 to 60% by weight, the balance being Cu, at least 5% by weight of Cr. If you use an alloy that contains ~15% by weight and the remainder is Fe, or a Ni-Ti alloy that exhibits a martensitic state at the operating temperature, the porous metal will exhibit an even greater effect of absorbing high-frequency vibrations, so it can be used over a wide range of frequencies. It can absorb and attenuate band vibrations.
なお、多孔質金属は、振動吸収能をもたない材料によっ
て形成してよいことは云う迄もないが、振動吸収能の有

とエラストマーの含浸量が少なくなって低周波振動の吸
収効果が薄れ、一方、骨格か細過ぎると剛性を高め難く
なるので、素材の種類にもよるが、空孔率が８０〜９６
％程度のものを使用するのが望ましい。It goes without saying that the porous metal may be made of a material that does not have vibration absorption ability, but regardless of whether it has vibration absorption ability or not, if the skeleton around the pores is too thick, the elastomer The amount of impregnation in the material decreases, reducing the effect of absorbing low-frequency vibrations.On the other hand, if the skeleton is too thin, it becomes difficult to increase the rigidity.
It is desirable to use something of the order of %.
また、多孔質金属の表面には必要に応じて空孔内のエラ
ストマーと一体化されたエラストマ一層を設けてよい。Furthermore, a single layer of elastomer integrated with the elastomer in the pores may be provided on the surface of the porous metal, if necessary.

ル以上の音は殆んど吸収されなかった。[Example 1] As shown in Fig. 1, porous holes were formed in the interskeletal pores 2 of a continuous porous metal 1 made of Fe-12 wt% Cr alloy with a porosity of about 94% and an average pore diameter of 1 mm. A composite anti-vibration sheet 4 with a total thickness of 10 mm was prepared by impregnating and filling polyurethane rubber 3 so that a single layer of elastomer with a thickness of about 1 mm was formed on the upper and lower surfaces of the quality metal 1, and this sheet was used as a shielding wall for a diesel engine. As a result of covering the surrounding area, the noise outside the shielding wall in the sound range from low frequencies of 30 cycles or less to high frequencies of 30 KHz was reduced by a wide range. For comparison, thickness 10
When a general rubber sheet with a diameter of 8 mm was used, almost no sound of 30 cycles or more was absorbed.

When we fabricated a composite vibration isolation sheet 4r with a thickness of 8 am as shown in Figure 2 and interposed it between the compressor and the steel pedestal, the vibrations transmitted to the pedestal were not only low-frequency components but also high-frequency components. The amount of deformation of the sheet 4' was reduced by about 40% compared to when only rubber was used as the material.
