Description

本発明は、高強度の素材と安価で軽量な低強度の素材を積層してパネル状のパネル材とした積層パネル材に関し、詳しくは、防振性、防音性や振動減衰性を付与した積層パネル材に関するものである。 The present invention relates to a laminated panel material made by laminating a high-strength material and a cheap, lightweight, low-strength material to form a panel-shaped panel material. It relates to panel material.

近年、炭素繊維強化プラスチック(CFRP:Carbon Fiber Reinforced Plastics)などの比較的高価だが軽量で高強度、高剛性の素材が開発され、発泡樹脂や木材などの安価で軽量の素材に高強度の素材を組み合わせて積層した様々な用途の積層パネルが提案されている。 In recent years, relatively expensive but lightweight, high-strength, and high-rigidity materials such as CFRP (Carbon Fiber Reinforced Plastics) have been developed. Laminated panels for various applications that are combined and laminated have been proposed.

例えば、特許文献1には、板状の樹脂発泡体5などの芯材の両面に金属シート4を接着し、その長辺の縁沿いにCFRPからなる補強層3を接着した積層パネル1が開示されている(特許文献1の明細書の段落[0061]~[0064]、図面の図1,図2等参照)。 For example, Patent Literature 1 discloses a laminated panel 1 in which a metal sheet 4 is adhered to both sides of a core material such as a plate-shaped resin foam 5, and a reinforcement layer 3 made of CFRP is adhered along the edges of the long sides. (see paragraphs [0061] to [0064] of the specification of Patent Document 1, Figures 1 and 2 of the drawings, etc.).

この特許文献1に記載の積層パネル1は、軽量、高剛性、安価で、かつ放熱性、耐熱寸法安定性に優れたとされ、パソコン、OA機器、AV機器、携帯電話、電話機、ファクシミリ、家電製品、玩具用品、フラットパネルディスプレイなどの種々の電気・電子機器の筐体用パネルに用いることができるとされている。 The laminated panel 1 described in Patent Document 1 is lightweight, highly rigid, inexpensive, and excellent in heat dissipation and heat-resistant dimensional stability. , toys, and flat panel displays.

また、このような特許文献1に記載の積層パネル1は、種々の筐体や床材、壁材などの用途に応じた所定の強度を有する構造用パネルとして用いる。このため、樹脂発泡体5と金属シート4、金属シート4とCFRPからなる補強層3とを接着する接着剤は、一般的に、硬化した時の接着強度(引張せん断接着強度)の高い、エポキシ系接着剤やアクリル系接着剤が使用されている(特許文献1の明細書の段落[0032],[0054]等参照)。 In addition, the laminated panel 1 described in Patent Document 1 is used as a structural panel having a predetermined strength according to applications such as various housings, floor materials, and wall materials. For this reason, the adhesive for bonding the resin foam 5 and the metal sheet 4, and the metal sheet 4 and the reinforcing layer 3 made of CFRP, is generally epoxy, which has a high adhesive strength (tensile shear adhesive strength) when cured. adhesives and acrylic adhesives are used (see paragraphs [0032], [0054], etc. of the specification of Patent Document 1).

このため、積層パネルに防振性、防音性、または振動減衰性を付与するためには、支持フレームや支持材と縁を切り、別途、ゴム弾性体からなるゴム材を貼着(接着)することで対処している。しかし、そうすると、ゴム材の分だけ重さや厚みが増え、接着手間が増えるだけでなく、せっかく極限まで積層パネルを軽量化したり厚さを薄くしたりしたことが台無しになってしまうという問題がある。 Therefore, in order to impart anti-vibration, sound-insulating, or vibration-damping properties to the laminated panel, the edges of the support frame and support material are cut, and a rubber material consisting of a rubber elastic body is attached (adhered) separately. is being dealt with. However, doing so increases the weight and thickness of the rubber material, which not only increases the time and effort required for bonding, but also ruins the efforts made to reduce the weight and thickness of the laminated panel to the utmost limit. .

一方、ブチルゴムは、ポリマー自体に自己粘着性を有し、反発力が非常に小さく、衝撃を吸収できる非常に高い衝撃エネルギー吸収性を有していることが知られており、振動減衰効果が高く、防振(振動防止)や免振・制振に活用されている。 On the other hand, butyl rubber is known to have self-adhesiveness in the polymer itself, very small repulsive force, and very high impact energy absorption that can absorb impact, and has a high vibration damping effect. , anti-vibration (anti-vibration) and anti-vibration/damping.

例えば、特許文献2には、拘束層としての床下パネル(3)と、被拘束層としての減衰層(2)とが設けられており、該減衰層(2)が、床下パネル(3)よりも小さな弾性係数を有しており、振動ダンパが車両底板(1)に固定された時に前記減衰層(2)が車両底板(1)と床下パネル(3)との間に配置されるようになっている車両底板(1)に使用するための振動ダンパが開示されている。また、減衰層(2)の材料としてブチルゴム、ブチルゴム箔が例示されている(特許文献2の特許請求の範囲の請求項1,14,20、明細書の段落[0035],[0036],[0040]、図面の図2,図5,図7等参照)。 For example, in Patent Document 2, an underfloor panel (3) as a constraining layer and a damping layer (2) as a constrained layer are provided. also has a small modulus of elasticity, such that said damping layer (2) is located between the vehicle bottom plate (1) and the underfloor panel (3) when the vibration damper is fixed to the vehicle bottom plate (1). A vibration damper for use in a vehicle bottom plate (1) is disclosed. In addition, butyl rubber and butyl rubber foil are exemplified as the material of the damping layer (2) (claims 1, 14, and 20 of the scope of patent document 2, paragraphs [0035], [0036], [ 0040], see FIGS. 2, 5 and 7 of the drawings).

しかし、特許文献2に記載の振動ダンパは、減衰層(2)の材料としてブチルゴムが念頭に置かれているものの、層間の結合は締結具で結合するものであり、高強度の素材と安価で軽量な低強度の素材を積層した構造用積層パネルの層間の接着剤にブチルゴムを使用するという着想はなく、車両の底板を兼用する振動ダンパの用途にとどまっていた。例えば、特許文献2には、減衰層を車両底板に固定するために、接着剤を設けるべきことが記載されている(特許文献2の明細書の段落[0010],[0011],[0038]、図面の図5参照)。 However, in the vibration damper described in Patent Document 2, although butyl rubber is considered as the material of the damping layer (2), the layers are connected by fasteners, which is a high-strength material and inexpensive. There was no idea of using butyl rubber as an adhesive between the layers of structural laminate panels that are made by laminating lightweight, low-strength materials, and the application was limited to vibration dampers that double as bottom plates of vehicles. For example, Patent Document 2 describes that an adhesive should be provided in order to fix the damping layer to the vehicle bottom plate (paragraphs [0010], [0011], [0038] of the specification of Patent Document 2). , see FIG. 5 of the drawings).

接着剤自体に防振性を付与するとの着想に至っていないのは、前述のように、所定の強度が求められる構造用パネルに積層パネルを採用した場合、その層間の接着剤は、硬化した時の接着強度(引張せん断接着強度)が高いものでないと、高強度の素材を用いても積層パネル材全体のせん断剛性(せん断弾性率)が低下してしまうと考えられていたからと推測される。 The reason why the idea of imparting vibration isolation to the adhesive itself has not been reached is because, as mentioned above, when a laminated panel is used for a structural panel that requires a certain level of strength, the adhesive between the layers is This is presumably because it was believed that unless the adhesive strength (tensile shear adhesive strength) of the laminated panel material is high, the shear rigidity (shear elastic modulus) of the entire laminated panel material will decrease even if a high-strength material is used.

しかし、本願発明者は、CFRPなどの高強度素材は、目付量を増加するなど、比較的簡単に強度調整が可能であり、積層パネル材全体のせん断剛性(せん断弾性係数)が低下しても他の素材の組み合わせ等により、この問題を解決できることを見出し、接着剤に衝撃吸収性能や振動減衰効果の高い自己粘着性を有するゴム状の弾性体材料を採用することを想到するに至った。 However, the inventor of the present application believes that the strength of high-strength materials such as CFRP can be adjusted relatively easily by increasing the basis weight, and even if the shear rigidity (shear elastic modulus) of the entire laminated panel material decreases, We found that this problem could be solved by combining other materials, etc., and came up with the idea of using a self-adhesive rubber-like elastic material with high shock absorption performance and vibration damping effect as the adhesive.

そこで、本発明は、前述した問題に鑑みて案出されたものであり、その目的とするところは、接着剤に衝撃吸収性能の高い自己粘着性を有するゴム状の弾性体材料を用いることにより重さや厚さを大きく変更しなくてもパネル材自体に防振性、防音性や振動減衰性を付与した積層パネル材を提供することにある。 Accordingly, the present invention has been devised in view of the problems described above, and an object of the present invention is to use a self-adhesive rubber-like elastic material with high impact absorption performance as an adhesive. To provide a laminated panel material imparting anti-vibration, sound-insulating and vibration damping properties to the panel material itself without greatly changing weight and thickness.

The high-strength sheet material is arranged in the outermost layer or the inner layer in contact with the outermost layer, and the interlayer adhesive that bonds the laminated layers contains a self-adhesive rubber material.

第6発明に係る構造用積層パネル材は、請求項1ないし5のいずれかに記載の合構造用積層パネル材において、前記低強度シート材は、木質系板材、樹脂プレート、樹脂発泡体、またはハニカム構造体であることを特徴とする。 A structural laminated panel material according to a sixth aspect of the invention is the composite structural laminated panel material according to any one of claims 1 to 5, wherein the low-strength sheet material is a wooden board, a resin plate, a resin foam, or It is characterized by being a honeycomb structure.

第1発明~第6発明によれば、最外層または最外層と接する内側の層に高強度シート材または高剛性シート材が配置されているので、積層パネル材を軽量としつつ断面性能を向上させることができるとともに、接着剤に衝撃吸収性能の高い材料を用いることにより重さや厚さを大きく変更しなくてもパネル材自体に防振性、防音性および振動減衰性を付与することができる。このため、積層パネル材を薄くしても振動が速やかに収束し、振動による不快感やビビり音などの騒音問題も解消することができる。 According to the first to sixth inventions, the high-strength sheet material or the high-rigidity sheet material is arranged in the outermost layer or the inner layer in contact with the outermost layer, so that the laminated panel material can be made lightweight and the cross-sectional performance can be improved. In addition, by using a material with high impact absorption performance for the adhesive, the panel material itself can be provided with anti-vibration, sound-proof and vibration-damping properties without significantly changing the weight and thickness. Therefore, even if the laminated panel material is made thin, the vibration is quickly converged, and noise problems such as unpleasant feeling and chattering due to vibration can be resolved.

特に、第3および第4発明によれば、層間接着剤にブチルゴム系粘着剤または弾性接着剤を用いるので、ブチルゴムの極めて高い振動減衰効果や弾性接着剤の振動減衰効果により積層パネル材の振動を速やかに収束させることができ、振動による起因する騒音問題や振動が続くことによる不快感や機器の誤作動などの不具合を解消することができる。 In particular, according to the third and fourth inventions, since a butyl rubber adhesive or an elastic adhesive is used as the interlayer adhesive, the vibration of the laminated panel material is suppressed by the extremely high vibration damping effect of the butyl rubber and the vibration damping effect of the elastic adhesive. It can be quickly converged, and problems such as noise caused by vibration, discomfort caused by continuous vibration, and malfunction of equipment can be resolved.

特に、第5発明によれば、高強度シート材の少なくとも一部に炭素繊維強化プラスチックを用いるので、FRPの軽量、高強度、高剛性の性能を発揮して構造用積層パネル材を軽量で薄くすることができるとともに、薄く軽量としても振動による起因する不具合を解消することができる。 In particular, according to the fifth invention, carbon fiber reinforced plastic is used for at least a part of the high-strength sheet material. In addition, even if it is made thin and light, it is possible to eliminate problems caused by vibration.

特に、第6発明によれば、低強度シート材が、木質系板材、樹脂プレート、樹脂発泡体、またはハニカム構造体であるので、構造用積層パネル材自体の断面性能を維持しつつ安価で軽量とすることができる。 In particular, according to the sixth invention, since the low-strength sheet material is a wooden board material, a resin plate, a resin foam, or a honeycomb structure, it is inexpensive and lightweight while maintaining the cross-sectional performance of the structural laminated panel material itself. can be

以下、本発明の実施形態に係る構造用積層パネル材について、図面を参照しながら詳細に説明する。 Hereinafter, a structural laminated panel material according to an embodiment of the present invention will be described in detail with reference to the drawings.

[第1実施形態]
先ず、図1を用いて、本発明の第1実施形態に係る積層パネル材1積層パネル材1について説明する。図1は、本発明の第1実施形態に係る積層パネル材1を示す模式断面図である。なお、図中のXは、積層パネル材1の長手方向Xを示し、Yは、積層パネル材1の短手方向Yを示し、Zは、上下方向Zを示している。
[First embodiment]
First, a laminated panel material 1 according to a first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a schematic cross-sectional view showing a laminated panel material 1 according to a first embodiment of the invention. In the drawings, X indicates the longitudinal direction X of the laminated panel member 1, Y indicates the lateral direction Y of the laminated panel member 1, and Z indicates the vertical direction Z. As shown in FIG.

第1実施形態に係る積層パネル材1は、高強度シート材2と低強度シート材3を組み合わせて積層して、種々の用途に応じた所定の設計強度を有する平面視矩形状のパネル材とした構造用積層パネル材である。図1に示すように、この積層パネル材1は、低強度シート材3の表裏両面に層間接着剤4で高強度シート材2を接着して積層したものである。 The laminated panel member 1 according to the first embodiment is a panel member having a rectangular shape in plan view and having a predetermined design strength according to various uses by combining and laminating high-strength sheet members 2 and low-strength sheet members 3. It is a laminated structural panel material. As shown in FIG. 1, this laminated panel material 1 is obtained by laminating a low-strength sheet material 3 with a high-strength sheet material 2 adhered to both front and back surfaces thereof with an interlayer adhesive 4 .

(高強度シート材)
高強度シート材2は、補強繊維を熱硬化性樹脂または熱可塑性樹脂からなるマトリックス樹脂で含侵硬化させてシート状とした繊維強化プラスチック(FRP: Fiber Reinforced Plastics)や金属シートなどの引張強度が450MPa以上となっている高強度の素材からなるシート状の部材である。450MPa以上としたのは、汎用鋼材である一般構造用圧延鋼材の強度を基準としたものである。また、高強度シート材2の引張強度の上限値としては、入手の容易なものを考慮すると後述の炭素繊維強化プラスチックの3300MPaと考えられる。
(High-strength sheet material)
The high-strength sheet material 2 is made of fiber reinforced plastics (FRP) formed by impregnating reinforcing fibers with a matrix resin made of a thermosetting resin or a thermoplastic resin and hardened, or a metal sheet having high tensile strength. It is a sheet-like member made of a high-strength material of 450 MPa or more. The strength of 450 MPa or more is based on the strength of general structural rolled steel, which is a general-purpose steel. In addition, the upper limit of the tensile strength of the high-strength sheet material 2 is considered to be 3300 MPa of carbon fiber reinforced plastic, which will be described later, considering that it is easily available.

補強繊維としては、ガラス繊維、カーボン繊維、アラミド繊維、ポリエチレン繊維、ザイロン繊維、ボロン繊維、などがあげられる。特に、補強繊維をカーボン繊維とした炭素繊維強化プラスチック(CFRP:Carbon Fiber Reinforced Plastics)は、引張強度が700~3300MPaと非常に強度の幅が広くて高強度であり、且つ、剛性率(引張弾性率)が55~450GPaと高剛性であり、軽量であるため好ましい。 Examples of reinforcing fibers include glass fibers, carbon fibers, aramid fibers, polyethylene fibers, Zylon fibers, and boron fibers. In particular, CFRP (Carbon Fiber Reinforced Plastics), which uses carbon fiber as the reinforcing fiber, has a very wide range of tensile strength of 700 to 3300 MPa, high strength, and rigidity (tensile elasticity modulus) is 55 to 450 GPa, which is high rigidity and light weight.

また、炭素繊維強化プラスチックは、炭素繊維シートの厚さや目付量の設定や変更を容易に行うことができ、比較的簡単に強度調整が可能である。このため、炭素繊維強化プラスチックは、接着剤変更に伴う接着強度低下に起因する積層パネル材1全体のせん断剛性(せん断弾性係数)の低下を補うことができる点で利点がある。 In addition, carbon fiber reinforced plastics allow easy setting and change of the thickness and basis weight of the carbon fiber sheet, and the strength can be adjusted relatively easily. Therefore, the carbon fiber reinforced plastic is advantageous in that it can compensate for the decrease in the shear rigidity (shear elastic modulus) of the entire laminated panel material 1 due to the decrease in adhesive strength due to the change of the adhesive.

図1に示すように、第1実施形態に係る積層パネル材1は、低強度シート材3の表裏両面に、最外層となる高強度シート材2が配置されて接着されている。ここで、積層パネル材1に曲げ応力が作用した場合、部材断面の端部に生じる縁応力が最大となる。このため、最外層となる低強度シート材3の表裏両面に引張強度の高い高強度シート材2が配置されていることで、この縁応力に効果的に対抗することができ、積層パネル材1の断面性能(断面積、断面二次モーメント、断面係数、断面二次半径などの断面に関する性能)が向上するからである。 As shown in FIG. 1, in the laminated panel material 1 according to the first embodiment, the high-strength sheet material 2 serving as the outermost layer is arranged and adhered to both front and back surfaces of the low-strength sheet material 3 . Here, when a bending stress acts on the laminated panel material 1, the edge stress generated at the end of the cross section of the member becomes maximum. Therefore, by arranging the high-strength sheet material 2 with high tensile strength on both front and back sides of the low-strength sheet material 3 which is the outermost layer, it is possible to effectively counter this edge stress, and the laminated panel material 1 This is because the cross-sectional performance (performance related to the cross section such as cross-sectional area, geometrical moment of inertia, section modulus, and cross-sectional secondary radius) is improved.

但し、本発明に係る積層パネル材は、高強度シート材2の外側にさらに化粧用シートなどの被覆層を設けてもよい。最外層に被覆層を設けることにより、積層パネル材1と同様の強度や剛性を確保しつつ見栄えを良くして、防傷性や耐久性を向上させることができるからである。要するに、本発明に係る積層パネル材は、最外層または最外層と接する内側の層に高強度シート材2や後述の高剛性シート材が設けられていればよい。 However, in the laminated panel material according to the present invention, a coating layer such as a decorative sheet may be further provided on the outer side of the high-strength sheet material 2 . This is because, by providing the outermost layer with the covering layer, it is possible to secure the same strength and rigidity as the laminated panel material 1, improve the appearance, and improve the damage resistance and durability. In short, in the laminated panel material according to the present invention, it is sufficient that the high-strength sheet material 2 or the high-rigidity sheet material described later is provided in the outermost layer or the inner layer in contact with the outermost layer.

また、高強度シート材2は、40GPa以上のヤング率(引張弾性率)を有する高剛性シート材としても構わない。高剛性シート材は、高強度シート材2と同様に積層パネル材とした際に種々の用途に応じた所定の設計強度や断面性能を発揮することができるからである。また、40GPaを基準としたのは、入手容易な汎用金属のマグネシウム合金のヤング率を基準としたものである。また、高剛性シート材のヤング率の上限値としては、入手の容易なものを考慮すると前述の炭素繊維強化プラスチックの450GPaと考えられる。 Also, the high-strength sheet material 2 may be a high-rigidity sheet material having a Young's modulus (tensile modulus) of 40 GPa or more. This is because, like the high-strength sheet material 2, the high-rigidity sheet material can exhibit predetermined design strength and cross-sectional performance according to various uses when formed into a laminated panel material. The standard of 40 GPa is based on the Young's modulus of magnesium alloy, which is an easily available general-purpose metal. In addition, the upper limit of the Young's modulus of the high-rigidity sheet material is considered to be 450 GPa of the carbon fiber reinforced plastic mentioned above, considering that it is easily available.

(低強度シート材)
低強度シート材3は、安価で軽量な板状の部材であり、高強度シート材2と比べて低強度、即ち、引張強度が450MPa未満の部材である。なお、低強度シート材3の引張強度の下限値は、後述の樹脂発泡体程度の100MPa以上と考えられる。具体的には、低強度シート材3は、木質系板材、樹脂プレート、樹脂発泡体、ハニカム構造体など、が好適に用いられる。汎用部材であり、安価でいつでも入手できるとともに積層パネル材1全体を軽量とすることができるからである。
(low-strength sheet material)
The low-strength sheet material 3 is a plate-shaped member that is inexpensive and lightweight, and has a lower strength than the high-strength sheet material 2, ie, a tensile strength of less than 450 MPa. In addition, the lower limit of the tensile strength of the low-strength sheet material 3 is considered to be 100 MPa or more, which is about the same as that of the resin foam described later. Specifically, the low-strength sheet material 3 is preferably made of a wooden board, a resin plate, a resin foam, a honeycomb structure, or the like. This is because it is a general-purpose member, can be obtained at any time at a low cost, and can make the entire laminated panel member 1 lightweight.

ここで、木質系板材とは、原料の木材を大小のエレメント(構成要素)に分解し、再構成した木質系材料からなる板材であり、具体的には、合板、パーティクルボード、配向性ストランドボード、ファイバーボードなどが挙げられる。 Here, the wood-based board refers to a board made of a wood-based material that is reconstituted by decomposing the raw material wood into large and small elements (components). Specifically, it includes plywood, particle board, and oriented strand board. , fiberboard, etc.

樹脂プレートは、ポリカーボネート、ポリアミド、ポリ塩化ビニル、ポリプロピレン、ABS樹脂、ポリイミドなどの汎用樹脂からなる板状の部材である。 The resin plate is a plate-like member made of general-purpose resin such as polycarbonate, polyamide, polyvinyl chloride, polypropylene, ABS resin, and polyimide.

樹脂発泡体は、樹脂を発泡させて発泡状(フォーム状)や多孔質形状として容積を大きくし、かさ比重を低下させた発泡プラスチックである。具体的には、樹脂発泡体は、軟質ポリウレタンフォーム、硬質ポリウレタンフォーム、ポリスチレンフォーム、ポリエチレンフォーム、ポリプロピレンフォーム、EVA架橋発泡体、PET樹脂発泡体、フェノールフォームなどが挙げられる。 A resin foam is a foamed plastic obtained by foaming a resin to form a foam or porous shape to increase the volume and reduce the bulk specific gravity. Specifically, resin foams include flexible polyurethane foams, rigid polyurethane foams, polystyrene foams, polyethylene foams, polypropylene foams, EVA cross-linked foams, PET resin foams, phenol foams, and the like.

ハニカム構造体は、軽量な素材から三角形・四角形・六角形などの平面視で同一図形の仕切で平面充填されたハチの巣状の構造体である。ハニカム構造体は、空間を多くとることで軽量化できるとともに、ハニカム構造で面圧縮に対抗できるため、積層パネル材1全体の曲げ剛性をあまり低下させることがない。 A honeycomb structure is a honeycomb-like structure in which lightweight materials are filled with partitions having the same shape when viewed from above, such as triangles, squares, and hexagons. The honeycomb structure can be made lighter by taking up a lot of space, and the honeycomb structure can withstand surface compression.

なお、低強度シート材3も、40GPa未満のヤング率(引張弾性率)を有する低剛性シート材としても構わない。複数層積層した積層シート材が全体として用途に応じた所定の設計強度や断面性能を有するパネル材であればよいからである。 The low-strength sheet material 3 may also be a low-rigidity sheet material having a Young's modulus (tensile modulus) of less than 40 GPa. This is because the laminated sheet material obtained by laminating a plurality of layers may be a panel material having predetermined design strength and cross-sectional performance according to the application as a whole.

(層間接着剤)
層間接着剤4は、図1に示すように、高強度シート材2と低強度シート材3とを接着する自己粘着性を有するゴム材を含有する接着剤である。勿論、同種または異種の高強度シート材2同士、同種または異種の低強度シート材3同士などの積層パネル材1の層間に介装されて接着するのに用いられてもよいことは云うまでもない。
(Interlayer adhesive)
The interlayer adhesive 4 is, as shown in FIG. 1, an adhesive containing a self-adhesive rubber material that bonds the high-strength sheet material 2 and the low-strength sheet material 3 together. Of course, it goes without saying that it may be used for interposing and bonding between the layers of the laminated panel material 1 such as the same or different high-strength sheet materials 2 or the same or different low-strength sheet materials 3 . do not have.

また、層間接着剤4は、ブチルゴムを含有するブチルゴム系粘着剤が好適である。ブチルゴムは、従来のエポキシ系接着剤やアクリル系接着剤よりは接着力や硬化時の接着強度(引張せん断接着強度)は低下する。しかし、一方、ブチルゴムは、天然ゴムと同等にポリマー自体に自己粘着性があり、振動減衰効果が高く衝撃吸収性が良好であり、積層パネル材自体に防振性、防音性、および振動減衰性を付与することができるという利点がある。なお、自己粘着性を有するゴム材としては、ブチルゴムの他、プロロプレンゴムを挙げることができる。 Moreover, the interlayer adhesive 4 is preferably a butyl rubber-based pressure-sensitive adhesive containing butyl rubber. Butyl rubber is lower in adhesive strength and adhesive strength when cured (tensile shear adhesive strength) than conventional epoxy adhesives and acrylic adhesives. On the other hand, butyl rubber, on the other hand, has self-adhesive properties similar to natural rubber. has the advantage of being able to provide In addition to butyl rubber, propylene rubber can be used as the self-adhesive rubber material.

同様に、層間接着剤4は、シリコーン系・変成シリコーン系またはポリオロールとポリイソジンアネート硬化剤で構成されるウレタン系など、からなり、硬化後も約-40℃~80℃の温度帯でせん断弾性率の変化がなだらかなゴム状弾性領域有し、ゴム状弾性を示す弾性接着剤としても構わない。弾性接着剤も、ブチルゴム系粘着剤と同様に、振動減衰効果が高く衝撃吸収性が良好だからである。 Similarly, the interlayer adhesive 4 is made of a silicone-based/modified silicone-based or a urethane-based adhesive composed of a polyol and a polyisodinate curing agent. The elastic adhesive may have a rubber-like elastic region in which the change in shear modulus is gentle and exhibit rubber-like elasticity. This is because the elastic adhesive also has a high vibration damping effect and good impact absorption, like the butyl rubber adhesive.

なお、当然ながら、積層パネル材1は、特許文献2に記載の振動ダンパと相違して、高強度シート材2と低強度シート材3との接着に、締結具で結合して補う必要はなく、層間接着剤4の接着力だけで足りる。 It should be noted that, of course, unlike the vibration damper described in Patent Document 2, the laminated panel material 1 does not need to be combined with fasteners to supplement the bonding between the high-strength sheet material 2 and the low-strength sheet material 3. , the adhesive strength of the interlayer adhesive 4 alone is sufficient.

以上説明した第1実施形態に係る積層パネル材1によれば、最外層に高強度シート材2が配置されているので、積層パネル材1を軽量としつつ断面性能を向上させることができる。また、層間接着剤4に衝撃吸収性能の高い材料を用いることにより重さや厚さを大きく変更しなくても積層パネル材1自体に防振性、防音性、および振動減衰性を付与することができる。このため、積層パネル材1を薄くしても振動が速やかに収束し、振動による不快感やビビり音などの騒音問題も解消することができる。 According to the laminated panel material 1 according to the first embodiment described above, since the high-strength sheet material 2 is arranged in the outermost layer, the laminated panel material 1 can be made lightweight and the cross-sectional performance can be improved. In addition, by using a material with high impact absorption performance for the interlayer adhesive 4, it is possible to provide the laminated panel material 1 itself with vibration-proof, sound-proof, and vibration-damping properties without significantly changing the weight and thickness. can. Therefore, even if the laminated panel member 1 is made thin, the vibration is quickly converged, and the problem of noise such as discomfort caused by the vibration and chattering can be resolved.

また、積層パネル材1によれば、層間接着剤4にブチルゴム系粘着剤を用いるので、ブチルゴムの極めて高い振動減衰効果で振動を速やかに収束させることができ、振動による起因する騒音問題や振動が続くことによる不快感や機器の誤作動などの不具合を解消することができる。 In addition, according to the laminated panel material 1, since the butyl rubber-based adhesive is used as the interlayer adhesive 4, the vibration can be quickly converged by the extremely high vibration damping effect of the butyl rubber, and the noise problem and vibration caused by the vibration can be eliminated. It is possible to eliminate problems such as discomfort and malfunction of equipment due to continuation.

さらに、積層パネル材1によれば、高強度シート材2に炭素繊維強化プラスチックを用いることにより、炭素繊維強化プラスチックの軽量、高強度、高剛性の性能を発揮して積層パネル材1を軽量で薄くすることができる。その上、積層パネル材1薄く軽量としてもブチルゴム系粘着剤からなる層間接着剤4を介装するので、振動に起因する不具合を解消することができる。 Furthermore, according to the laminated panel material 1, by using carbon fiber reinforced plastic for the high-strength sheet material 2, the lightweight, high strength, and high rigidity performance of the carbon fiber reinforced plastic can be exhibited, and the laminated panel material 1 can be made lightweight. can be thinned. Moreover, even if the laminated panel material 1 is made thin and light, the interlayer adhesive 4 made of a butyl rubber-based adhesive is interposed, so that problems caused by vibration can be eliminated.

[第2実施形態]
次に、図2を用いて、本発明の第2実施形態に係る積層パネル材1’について説明する。図2は、本発明の第2実施形態に係る積層パネル材1’を示す模式断面図である。なお、図中のXは、積層パネル材1の長手方向Xを示し、Yは、積層パネル材1の短手方向Yを示し、Zは、上下方向Zを示している。第2実施形態に係る積層パネル材1’が、前述の第1実施形態に係る積層パネル材1と相違する点は、高強度シート材2と低強度シート材3の層数と層間接着剤の層数の違いであり、同一構成は同一符号を付し、詳細な説明を省略する。
[Second embodiment]
Next, a laminated panel material 1' according to a second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a schematic cross-sectional view showing a laminated panel material 1' according to a second embodiment of the invention. In the drawings, X indicates the longitudinal direction X of the laminated panel member 1, Y indicates the lateral direction Y of the laminated panel member 1, and Z indicates the vertical direction Z. As shown in FIG. The laminated panel material 1' according to the second embodiment differs from the laminated panel material 1 according to the first embodiment described above in the number of layers of the high-strength sheet material 2 and the low-strength sheet material 3 and the number of layers of the interlayer adhesive. The difference is the number of layers, and the same configurations are denoted by the same reference numerals, and detailed description thereof is omitted.

第2実施形態に係る積層パネル材1’は、図2に示すように、3層の低強度シート材3と、それらの間に介装される2層の高強度シート材2と、3層の低強度シート材3の表裏外側に配置された2層の高強度シート材2と、それらの間を接着する6層の層間接着剤4など、から構成されている。 As shown in FIG. 2, the laminated panel material 1' according to the second embodiment includes three layers of low-strength sheet material 3, two layers of high-strength sheet material 2 interposed therebetween, and three layers of It is composed of two layers of high-strength sheet material 2 arranged on the front and back outer sides of a low-strength sheet material 3 and six layers of interlayer adhesive 4 for bonding between them.

また、最外層の2層の高強度シート材2と、低強度シート材3の間に介装される2層の高強度シート材2とは、種類が相違する。例えば、最外層の2層の高強度シート材2は、炭素繊維強化プラスチック2aであり、低強度シート材3の間に介装される2層の高強度シート材2は、厚さ3mm以下の薄鋼板2bである。 The two layers of high-strength sheet materials 2 as the outermost layers and the two layers of high-strength sheet materials 2 interposed between the low-strength sheet materials 3 are different in type. For example, the outermost two high-strength sheet materials 2 are made of carbon fiber reinforced plastic 2a, and the two high-strength sheet materials 2 interposed between the low-strength sheet materials 3 have a thickness of 3 mm or less. It is the thin steel plate 2b.

このように、第2実施形態に係る積層パネル材1’も積層パネル材1と同様に、少なくとも、最外層または被覆層を最外層としてその内側の層には、高強度シート材2(炭素繊維強化プラスチック2a)が配置されている。積層パネル材1と同様に、積層パネル材1’の断面性能が向上するからである。 Thus, in the laminated panel material 1' according to the second embodiment, as in the laminated panel material 1, at least the outermost layer or the coating layer is the outermost layer, and the inner layer contains the high-strength sheet material 2 (carbon fiber A reinforced plastic 2a) is arranged. This is because, like the laminated panel material 1, the cross-sectional performance of the laminated panel material 1' is improved.

勿論、高強度シート材2および低強度シート材3は、前述の高剛性シート材および低剛性シート材としても構わない。複数層積層した積層シート材が全体として用途に応じた所定の設計強度を有するパネル材であればよいからである。 Of course, the high-strength sheet material 2 and the low-strength sheet material 3 may be the above-described high-rigidity sheet material and low-rigidity sheet material. This is because it is sufficient that the laminated sheet material obtained by laminating a plurality of layers as a whole has a predetermined design strength according to the application.

以上説明した第2実施形態に係る積層パネル材1’によれば、前記作用効果に加え、積層パネル材1’の積層数が増えるために、接着剤変更に伴う接着強度低下に起因する積層パネル材1全体のせん断剛性(せん断弾性係数)の低下を補い易くなる。 According to the laminated panel material 1' according to the second embodiment described above, in addition to the above effects, the number of laminated layers of the laminated panel material 1' increases, so the laminated panel material caused by the decrease in adhesive strength due to the change of the adhesive It becomes easy to compensate for the decrease in the shear rigidity (shear elastic modulus) of the entire material 1 .

また、積層パネル材1’によれば、繊維方向に強くこれと直交する方向に力の弱い異方性を有し、強度の高い炭素繊維強化プラスチック2aを最外層または最外層と接する内側の層に配置するとともに、それより内側に等方性を有してせん断力に対抗できる金属シートである薄鋼板2bを配置することにより、接着強度低下に起因する積層パネル材1全体のせん断剛性の低下を補うことができる。 In addition, according to the laminated panel material 1', the outermost layer or the inner layer in contact with the outermost layer is the carbon fiber reinforced plastic 2a having anisotropy that is strong in the fiber direction and weak in the direction perpendicular to it, and has high strength. In addition, by arranging the thin steel plate 2b, which is a metal sheet that has isotropy and can resist shearing force, on the inner side, the shear rigidity of the entire laminated panel material 1 is reduced due to the decrease in adhesive strength. can be compensated for.

このように、本実施形態に係る積層パネル材1’は、パネル材の設計段階で従来の接着剤と比べて層間接着剤4の接着強度の低下を見込み、他の複数層の高強度シート材2のせん断剛性等の強度を上げて補うことで、積層パネル材1’自体に防振性、防音性、および振動減衰性を付与することができる。また、防振性を付与する際に、積層パネル材1’自体の重さや厚さを大きく変更する必要もない。 As described above, the laminated panel material 1' according to the present embodiment anticipates a decrease in the adhesive strength of the interlayer adhesive 4 compared to the conventional adhesive at the design stage of the panel material, and other multi-layered high-strength sheet materials. By increasing the strength such as the shear rigidity of 2 and compensating for it, the laminated panel material 1' itself can be provided with anti-vibration properties, sound insulation properties, and vibration damping properties. In addition, it is not necessary to greatly change the weight and thickness of the laminated panel material 1' itself when imparting vibration-proof properties.

以上、本発明の実施形態に係る積層パネル材1,1’について詳細に説明した。しかし、前述したまたは図示した実施形態は、いずれも本発明を実施するにあたって具体化した一実施形態を示したものに過ぎない。よって、例示した実施形態によって本発明の技術的範囲が限定的に解釈されてはならないものである。 The laminated panel members 1, 1' according to the embodiments of the present invention have been described above in detail.

In addition, according to the first and second inventions, since the butyl rubber-based pressure-sensitive adhesive or elastic adhesive is used as the interlayer adhesive, vibration of the laminated panel material can be reduced by the extremely high vibration damping effect of the butyl rubber and the vibration damping effect of the elastic adhesive. can be quickly converged, and problems such as noise problems caused by vibrations, discomfort caused by continuous vibrations, and equipment malfunctions can be resolved.
Moreover, according to the first and second inventions, since carbon fiber reinforced plastic is used for at least a part of the high-strength sheet material, the performance of light weight, high strength, and high rigidity of FRP can be exhibited to produce a structural laminated panel. The material can be made light and thin, and even if it is made thin and light, problems caused by vibration can be eliminated.
Furthermore, according to the first and second inventions, since the low-strength sheet material is a wooden board material, it is possible to reduce the cost and weight while maintaining the cross-sectional performance of the laminated panel material itself.
