Description

本発明は、２以上の熱可塑性樹脂からなる樹脂部材の重ね合わせ箇所を接続する樹脂部材の接続方法に関するものである。 The present invention relates to a method of connecting resin member connecting the points overlay resin member composed of two or more thermoplastic resins.

樹脂に強化用繊維材が混入されてなる繊維強化プラスチック（ＦＲＰ）は、軽量かつ高強度であることから、自動車産業、建設産業、航空産業など、様々な産業分野で使用されている。   Fiber reinforced plastic (FRP) in which a reinforcing fiber material is mixed into a resin is lightweight and has high strength, and is therefore used in various industrial fields such as the automobile industry, construction industry, and aviation industry.

そして、ＦＲＰ部材同士の接続方法に関しては、接着剤を介して接続する方法やボルトによる接続方法、さらにはそれらを組み合わせた接続方法などが一般に用いられている。   And regarding the connection method of FRP members, the method of connecting through an adhesive agent, the connection method by a volt | bolt, the connection method which combined those, etc. are generally used.

ところで、部材同士の接続に関し、被接続部材がアルミ板や鋼板等からなる場合に、スポット溶接や摩擦攪拌接続、メカニカルクリンチ、ろう付け、ネジ留めといった様々な接続方法がある中で、セルフピアスリベットによる接続方法が適用されることがある。   By the way, with regard to the connection between members, there are various connection methods such as spot welding, friction stir connection, mechanical clinching, brazing, and screwing when the connected member is made of an aluminum plate or a steel plate. The connection method by may be applied.

このセルフピアスリベットによる接続方法は、その載置面に凹溝を具備するリベットダイスの上にたとえば２枚の金属板を積層姿勢で載置し、端面とこの端面から突出するピアスとからなる筒状のリベットを金属板の上方で位置決めし、パンチでこのリベットを金属板に打ち込むことでリベットを上板に貫通させ、この過程でリベットが塑性変形しながらピアスの先端を外側に広げ、さらにリベットを打ち込むことでピアスの先端が下板内でさらに広げられ、ピアスの打ち込み過程で上下の金属板を塑性変形させて双方をピアスを介してインターロック接続するものである。   In this connection method using self-piercing rivets, a cylinder comprising, for example, two metal plates placed in a stacked posture on a rivet die having a concave groove on the mounting surface, and an end face and a piercing projecting from the end face. The rivet is positioned above the metal plate, and the rivet is penetrated into the upper plate by punching the metal plate with a punch. In this process, the rivet is plastically deformed and the tip of the pierce is spread outward. , The tip of the pierce is further expanded in the lower plate, and the upper and lower metal plates are plastically deformed during the piercing process to interlock the two via the piercing.

セルフピアスリベットによる接続方法によれば、たとえば金属上板に対して事前に穴あけをおこなう必要がなく、さらに３枚、４枚といった金属板同士の接続も可能であることから、効率的に２以上の金属部材同士を高強度で接続することができる。   According to the connection method using the self-piercing rivet, for example, it is not necessary to make a hole in advance on the metal upper plate, and further, it is possible to connect three or four metal plates to each other. These metal members can be connected with high strength.

このように様々なメリットを奏するセルフピアスリベットによる接続方法を上記するＦＲＰ部材同士の接続に適用せんとする試みもおこなわれており、さらには公開技術である特許文献１にもその内容が開示されている。ここで開示される接続方法は、接続される２つのＦＲＰ部材間に接着剤を塗工し、この接着剤が未硬化の状態でセルフピアスリベットを打ち込んで、リベットを上方のＦＲＰ部材を貫通させて下方のＦＲＰ部材内にその先端を留まらせるものである。   Attempts have also been made to apply the connection method using self-piercing rivets, which have various merits, to the connection between the FRP members described above, and the contents thereof are also disclosed in Patent Document 1 which is a publicly available technology. ing. In the connection method disclosed herein, an adhesive is applied between two FRP members to be connected, a self-piercing rivet is driven in a state where the adhesive is uncured, and the rivet passes through the upper FRP member. Thus, the tip is kept in the FRP member below.

しかし、このように樹脂部材同士の接続にセルフピアスリベットによる接続方法を適用すると、たとえば上下２枚の樹脂部材を接続固定することはできるものの、双方の界面のシール性を保証することはできない。   However, when the connection method using the self-piercing rivet is applied to the connection between the resin members in this way, for example, the upper and lower two resin members can be connected and fixed, but the sealability at the interface between them cannot be guaranteed.

特開２００７−２２９９８０号公報JP 2007-229980 A

本発明は上記する問題に鑑みてなされたものであり、２以上の熱可塑性樹脂からなる樹脂部材の重ね合わせ箇所をセルフピアスリベットによる接続方法を適用して接続する樹脂部材の接続方法に関し、接続される樹脂部材同士の界面のシール性が保証され、さらには接続強度の高い接続構造を得ることのできる樹脂部材の接続方法を提供することを目的とする。 The present invention has been made in view of the above-described problems, and relates to a resin member connection method for connecting overlapping portions of resin members made of two or more thermoplastic resins by applying a connection method using a self-piercing rivet. Another object of the present invention is to provide a method for connecting resin members, in which the sealing property at the interface between the resin members is ensured and a connection structure with high connection strength can be obtained.

前記目的を達成すべく、本発明による樹脂部材の接続方法は、２以上の熱可塑性樹脂からなる樹脂部材の重ね合わせ箇所を接続する樹脂部材の接続方法であって、２以上の前記樹脂部材をその間に少なくとも１つの導電性の金属板を介層させながら重ね合わせて重ね合わせ箇所を形成し、該金属板を加熱して該金属板と接する上下の樹脂部材双方の少なくとも金属板との界面を溶融させて該金属板に溶着させる第１のステップ、前記重ね合わせ箇所の上方からセルフピアスリベットを打ち込んで最下層の樹脂部材の内部まで到達させ、溶着と、リベット接続と、セルフピアスリベットが金属板を貫通した際にできたバリが該金属板の下層の樹脂部材内に食い込んでいること、によって樹脂部材同士を接続する第２のステップからなるものである。   In order to achieve the above object, a resin member connection method according to the present invention is a resin member connection method for connecting overlapping portions of resin members made of two or more thermoplastic resins, and the two or more resin members are connected. In the meantime, at least one conductive metal plate is interposed and overlapped to form an overlapped portion, and the metal plate is heated to form an interface between at least the upper and lower resin members in contact with the metal plate. A first step of melting and welding to the metal plate; a self-piercing rivet is driven from above the overlapping position to reach the inside of the lowermost resin member; welding, rivet connection, and self-piercing rivet are metal It consists of a second step of connecting the resin members by the burr formed when penetrating the plate biting into the resin member under the metal plate .

本発明の部材の接続方法は、２以上の熱可塑性樹脂からなる樹脂部材をセルフピアスリベットを用いて接続するに当たり、樹脂部材の間に導電性の金属板を介層させてこれに通電等することによって加熱し、金属板と接する双方の樹脂部材の界面やその近傍を溶融させて金属板に溶着させることで金属板を介してその上下の樹脂部材の界面のシール性を保証するものである。さらに、セルフピアスリベットが金属板を貫通した際に確実に形成されるバリが下層の樹脂部材に食い込むことにより、セルフピアスリベットによるアンカー効果のみならず、このバリによるアンカー効果によって接続強度を高めることができるものである。なお、この接続強度に関しては、従来のセルフピアスリベットのみによるアンカー効果に起因する接続強度に対して、セルフピアスリベットと金属板のバリの双方のアンカー効果と、金属板にその上下の樹脂部材が溶着してなる溶着強度の総和からなる接続強度が期待できる。   In the method for connecting members according to the present invention, when connecting a resin member made of two or more thermoplastic resins using a self-piercing rivet, a conductive metal plate is interposed between the resin members to energize it. By heating, the interface between both resin members in contact with the metal plate and the vicinity thereof are melted and welded to the metal plate, thereby ensuring the sealing property at the interface between the upper and lower resin members via the metal plate. . Furthermore, the burr that is reliably formed when the self-piercing rivet penetrates the metal plate bites into the resin member in the lower layer, thereby enhancing the connection strength not only by the anchor effect by the self-piercing rivet but also by the anchor effect by this burr. It is something that can be done. Regarding the connection strength, the anchor effect of both the self-piercing rivet and the burr of the metal plate and the upper and lower resin members of the metal plate are compared to the connection strength caused by the anchor effect of the conventional self-piercing rivet alone. A connection strength consisting of the total weld strength formed by welding can be expected.

「２以上の熱可塑性樹脂からなる樹脂部材」ゆえに、接続される繊維強化樹脂材は、２つであっても３以上であってもよいし、それらの形状形態も、平面状のもの同士を接続する形態や、湾曲状の３次元形状のもの同士を接続する形態、２以上の平面が相互に傾斜した３次元形状のもの同士、もしくはこのような３次元形状のものと平面状のものを接続する形態などであってもよい。さらに、接続される繊維強化樹脂材の用途としては、車両のピラーやロッカー、床下フロアなどの車両の骨格構造部材、ドアアウターパネルやフードなどの意匠性が要求される非構造部材などを挙げることができる。なお、３以上の樹脂部材を接続する場合であっても、隣接する樹脂部材のそれぞれの界面に金属板を介層させるため、たとえば３つの樹脂部材を接続する場合はそれぞれの接続箇所において２つの金属板が使用されることになる。   Because of the “resin member made of two or more thermoplastic resins”, the number of fiber reinforced resin materials to be connected may be two or three or more, and the shape and form thereof may be flat. Forms of connection, forms of connecting curved three-dimensional shapes, forms of two or more three-dimensional shapes inclined with respect to each other, or such three-dimensional shapes and planar ones It may be a form of connection. Furthermore, the use of the fiber reinforced resin material to be connected includes vehicle structural members such as vehicle pillars and lockers, underfloor floors, and non-structural members that require design properties such as door outer panels and hoods.

For example, iron, steel, aluminum, copper, chromium, nickel alone or these Two or more alloys can be used. In addition to energizing the metal plate to generate Joule heat, there is a method of melting the interface of the resin member with the metal plate by high-frequency heating.

また、２以上の樹脂部材は、長繊維や短繊維がマトリックス樹脂内にランダムに、もしくは所定の配向をもって埋設されたプリプレグシートやその積層体、長繊維よりも長い連続繊維がマトリックス樹脂内に一方向に配向された一方向材（ＵＤ材）からなるプリプレグシートやその積層体、連続繊維を含有する複数のプリプレグシートのそれぞれの連続繊維の配向が０度、９０度、±４５度等になるように積層してなる擬似等方材、連続繊維からなる経糸と緯糸からなる織物をマトリックス樹脂内に含有させてなるプリプレグシートやその積層体などを挙げることができる。また、プリプレグシートやその積層体のみならず、別途の成形型内で射出成形やＲＴＭ成形、ＳＭＣ成形等されて製作された部材などであってもよい。   In addition, two or more resin members include a prepreg sheet in which long fibers and short fibers are embedded randomly or in a predetermined orientation in the matrix resin, a laminate thereof, and continuous fibers longer than the long fibers are integrated in the matrix resin. A prepreg sheet made of a unidirectional material (UD material) oriented in the direction, a laminate thereof, and a plurality of prepreg sheets containing continuous fibers have orientations of 0 degrees, 90 degrees, ± 45 degrees, etc. Examples thereof include a quasi-isotropic material formed by laminating, a prepreg sheet in which a woven fabric composed of warps and wefts composed of continuous fibers is contained in a matrix resin, and a laminate thereof. Further, not only a prepreg sheet and a laminate thereof, but also a member manufactured by injection molding, RTM molding, SMC molding or the like in a separate mold.

This connection structure is a resin member connection structure made of two or more thermoplastic resins, the two or more resin members, and upper and lower resins. A conductive metal plate interposed between the members, a self-piercing rivet that reaches the middle of the lowermost resin member from the uppermost resin member, and passes through the middle metal plate, and a self-piercing rivet The burrs formed when the metal plate penetrates the metal plate bite into the resin member below the metal plate and the upper and lower resin members of the metal plate are welded to the metal plate. .

既述するように、本発明の接続構造によれば、金属板と樹脂部材の界面との溶着によって双方の密着性、シール性が保証され、かつ、セルフピアスリベットと金属板のバリ双方のアンカー効果による機械的な接続強度と、溶着による接続強度からなる極めて高い接続強度を備えた接続構造となる。   As described above, according to the connection structure of the present invention, the adhesion between both the metal plate and the resin member is ensured, and both the adhesiveness and the sealing performance are ensured, and both the self-piercing rivet and the metal plate burrs are anchors. A connection structure having a very high connection strength consisting of a mechanical connection strength due to the effect and a connection strength due to welding is obtained.

以上の説明から理解できるように、本発明の樹脂部材の接続方法によれば、樹脂部材の間に導電性の金属板を介在させてこれを加熱し、樹脂部材の金属板との界面を溶融させて金属板と溶着することによって樹脂部材同士の界面のシール性を担保することができる。さらに、２以上の樹脂部材と樹脂部材間に介在する金属板をセルフピアスリベットが貫通することによって、本来的なセルフピアスリベットによるアンカー効果に加えて、セルフピアスリベットが金属板を貫通する際にできるバリによるアンカー効果が付加され、さらにこれらに金属板と樹脂部材との溶着強度が付加されて樹脂部材の接続箇所における接続強度が決定されることから、従来のセルフピアスリベットのみによる接続強度に比して格段に高い接続強度を有する接続構造を得ることができる。 As can be understood from the above description , according to the resin member connection method of the present invention, a conductive metal plate is interposed between the resin members and heated to melt the interface between the resin member and the metal plate. The sealing performance of the interface between the resin members can be ensured by welding the metal plate. Furthermore, when the self-piercing rivet penetrates the metal plate, in addition to the anchor effect by the inherent self-piercing rivet, the self-piercing rivet penetrates through the metal plate interposed between two or more resin members and the resin member. Since the anchor effect by the burr that can be added is added, and the welding strength between the metal plate and the resin member is added to these, the connection strength at the connection point of the resin member is determined, so the connection strength only by the conventional self-piercing rivet A connection structure having a remarkably high connection strength can be obtained.

Although the illustrated example shows a method of connecting two resin members and a connection structure thereof, it is needless to say that three or more resin members may be connected using the illustrated method.

（樹脂部材の接続方法の第１の実施の形態、および樹脂部材の接続構造）
図１〜４は順に、本発明の樹脂部材の接続方法を説明するフロー図となっている。具体的には、図１はセルフピアスリベット接続に供されるシリンダ機構とリベットダイスの縦断面図であり、図２は２つの樹脂部材の重ね合わせ箇所がリベットダイスの載置台上に載置され、樹脂部材の間に介在する金属板に通電している状態を説明した図であり、図３はリベットを打ち込んでいる状態を説明した図であり、図４はリベットが完全に打ち込まれ、接続構造が形成された状態を説明した図である。 (First embodiment of resin member connection method and resin member connection structure)
1-4 is a flowchart explaining the connection method of the resin member of this invention in order. Specifically, FIG. 1 is a vertical cross-sectional view of a cylinder mechanism and a rivet die used for self-piercing rivet connection, and FIG. 2 shows a place where two resin members are overlapped on a mounting table for the rivet die. FIG. 3 is a diagram illustrating a state in which a metal plate interposed between resin members is energized, FIG. 3 is a diagram illustrating a state in which a rivet is driven, and FIG. 4 is a diagram in which the rivet is completely driven and connected. It is a figure explaining the state in which the structure was formed.

以下、本発明の樹脂部材の接続方法を適用して上下２つの繊維強化樹脂部材同士を接続する方法を説明する。   Hereinafter, a method of connecting two upper and lower fiber reinforced resin members by applying the resin member connection method of the present invention will be described.

図１ａで示すように、２つの繊維強化樹脂部材の一部を重ね合わせた重ね合わせ箇所が載置されるリベットダイス３と、その上方に位置してシリンダ１内をパンチ２が摺動自在なシリンダ機構とからなる製造システムを用意する。   As shown in FIG. 1a, a rivet die 3 on which an overlapped portion where two fiber reinforced resin members are overlapped is placed, and a punch 2 is slidable in a cylinder 1 positioned above the rivet die. A manufacturing system comprising a cylinder mechanism is prepared.

リベットダイス３は、図１ｂで示すようにその平面視が円形であり、繊維強化樹脂材が載置される載置面３ａにはリング状の凹溝３ｂが形成されている。   As shown in FIG. 1b, the rivet die 3 is circular in plan view, and a ring-shaped concave groove 3b is formed on the mounting surface 3a on which the fiber reinforced resin material is mounted.

さらに、リベットダイス３内には不図示のヒータが内蔵されていてもよい。   Furthermore, a heater (not shown) may be incorporated in the rivet die 3.

シリンダ１内では、その内部で摺動するパンチ２の下面にリベット４が吸着等で仮固定されるようになっている。   In the cylinder 1, the rivet 4 is temporarily fixed to the lower surface of the punch 2 that slides inside the cylinder 1 by suction or the like.

使用されるリベット４は、その平面視が円形の端面４ｂと、この端面４ｂから突出する筒状のピアス４ａとからなる縦断面視が門形を呈したものであり、その素材はアルミニウムやその合金、鋼などから形成される。   The rivet 4 to be used has a portal shape in a longitudinal sectional view composed of an end face 4b having a circular shape in plan view and a cylindrical piercing 4a protruding from the end face 4b. It is formed from an alloy, steel or the like.

図２で示すように、用意された製造システムを構成するリベットダイス３の載置面３ａ上に、繊維強化樹脂部材からなる上方の樹脂部材６と下方の樹脂部材５の重ね合わせ箇所を位置決めし、この重ね合わせ箇所に導電性の金属板７を介在させた状態で、上方の樹脂部材６上にシリンダ１をセットする。   As shown in FIG. 2, on the mounting surface 3a of the rivet die 3 constituting the prepared manufacturing system, the overlapping portion of the upper resin member 6 made of fiber reinforced resin member and the lower resin member 5 is positioned. The cylinder 1 is set on the upper resin member 6 in a state where the conductive metal plate 7 is interposed at the overlapping portion.

ここで、上方の樹脂部材６、下方の樹脂部材５を形成する繊維強化樹脂部材のマトリックス樹脂は熱可塑性樹脂からなり、このマトリックス樹脂の内部に適宜の繊維材が混入されている。   Here, the matrix resin of the fiber reinforced resin member forming the upper resin member 6 and the lower resin member 5 is made of a thermoplastic resin, and an appropriate fiber material is mixed inside the matrix resin.

樹脂部材５，６のマトリックス樹脂として使用される熱可塑性樹脂としては、ポリエチレン（ＰＥ）やポリプロピレン（ＰＰ）、ナイロン（ＰＡ：ナイロン６、ナイロン６６など）、ポリアセタール（ＰＯＭ）、ポリエチレンテレフタレート（ＰＥＴ）などの結晶性プラスチック、ポリスチレン（ＰＳ）、ポリ塩化ビニル（ＰＶＣ）、ポリメタクリル酸メチル（ＰＭＭＡ）、ＡＢＳ樹脂、熱可塑性エポキシなどの非結晶性プラスチックなどのうちのいずれか一種もしくはそれらの２種以上を混合した材料を適用することができる。   The thermoplastic resin used as the matrix resin for the resin members 5 and 6 includes polyethylene (PE), polypropylene (PP), nylon (PA: nylon 6, nylon 66, etc.), polyacetal (POM), polyethylene terephthalate (PET). Any one of crystalline plastics such as polystyrene (PS), polyvinyl chloride (PVC), polymethyl methacrylate (PMMA), ABS resin, thermoplastic epoxy, etc., or two of them A material in which the above is mixed can be applied.

また、マトリックス樹脂内に含有されている繊維材（短繊維、長繊維、連続繊維）としては、ボロンやアルミナ、炭化ケイ素、窒化ケイ素、ジルコニアなどのセラミック繊維や、ガラス繊維や炭素繊維といった無機繊維、銅や鋼、アルミニウム、ステンレス等の金属繊維、ポリアミドやポリエステルなどの有機繊維のいずれか一種もしくは２種以上の混合材を適用することができる。   Moreover, as fiber materials (short fibers, long fibers, continuous fibers) contained in the matrix resin, ceramic fibers such as boron, alumina, silicon carbide, silicon nitride, and zirconia, and inorganic fibers such as glass fibers and carbon fibers Any one kind or a mixture of two or more kinds of metal fibers such as copper, steel, aluminum and stainless steel, and organic fibers such as polyamide and polyester can be applied.

また、樹脂部材５，６の重ね合わせ箇所においてそれらの間に介在する金属板７は導電性を有する板材であればよいが、鉄、鋼、アルミニウム、銅、クロム、ニッケルを単独で、もしくはこれらの２種以上の合金からなる板を使用することができる。   Moreover, the metal plate 7 interposed between the resin members 5 and 6 may be any conductive plate material, but iron, steel, aluminum, copper, chromium, nickel alone or these may be used. A plate made of two or more of these alloys can be used.

樹脂部材５，６の重ね合わせ箇所を載置面３ａ上に位置決めした状態で、それらの間に介在する金属板７に電源回路を設置して通電することにより、金属板７で生じるジュール熱によって金属板７と接する樹脂部材５，６双方の界面を溶融させ、金属板７と溶着させる（第１のステップ）。   In a state where the overlapping portions of the resin members 5 and 6 are positioned on the mounting surface 3a, a power supply circuit is installed in the metal plate 7 interposed therebetween and energized, so that Joule heat generated in the metal plate 7 The interfaces of both the resin members 5 and 6 in contact with the metal plate 7 are melted and welded to the metal plate 7 (first step).

次に、図３で示すように、シリンダ１内でパンチ２を摺動させ、パンチ２からリベット４を上方の樹脂部材６側に押し込むことにより（押圧力Ｑ）、リベット４のピアス４ａが上方の樹脂部材６に打ち込まれてこれを貫通し、金属板７を貫通し、さらに下方の樹脂部材５にピアス４ａの先端が入り込むことになる。   Next, as shown in FIG. 3, the pierce 4a of the rivet 4 is moved upward by sliding the punch 2 in the cylinder 1 and pushing the rivet 4 from the punch 2 toward the upper resin member 6 (pressing force Q). The resin member 6 is driven through and penetrates the metal plate 7, and the tip of the pierce 4 a enters the resin member 5 below.

なお、リベットダイス３内に不図示のヒータが内蔵されている場合は、このリベット４の打ち込みに際してヒータを稼動させて下方の樹脂部材５の重ね合わせ箇所を溶融させてもよい。   If a heater (not shown) is built in the rivet die 3, the heater may be operated when the rivet 4 is driven to melt the overlapping portion of the lower resin member 5.

ピアス４ａは上方の樹脂部材６を貫通する過程で内側から圧力ｑを受けて外側に開き、さらに金属板７を貫通し、下方の樹脂部材５内に打ち込まれる過程でも内側から圧力を受けて外側に開くことになる。このようにリベット４の打ち込み過程で筒状のピアス４ａが外側へ変位するのは、ピアス４ａの先端内側が先鋭テーパー状に形成されていること、リベットダイス３の載置面３ａに設けられたリング状の凹溝３ｂで囲まれる中央部分が筒状のピアス４ａの内側で上方凸をなしていること、筒状のピアス４ａの内側で比較的剛性の高い樹脂部材５，６や金属板７が介在していること、などの種々の要素によるものである。   The pierce 4a receives the pressure q from the inside in the process of passing through the upper resin member 6 and opens to the outside. Further, the pierce 4a passes through the metal plate 7 and receives the pressure from the inside in the process of being driven into the lower resin member 5. Will be opened. As described above, the cylindrical pierce 4a is displaced outward during the driving process of the rivet 4 because the tip inner side of the pierce 4a is formed in a sharp taper, and the mounting surface 3a of the rivet die 3 is provided. The central portion surrounded by the ring-shaped concave groove 3b is convex upward inside the cylindrical pierce 4a, and the resin members 5 and 6 and the metal plate 7 having relatively high rigidity inside the cylindrical pierce 4a. This is due to various factors such as intervening.

そして、リベット４が金属板７を貫通した際に金属板７にはバリ７ａが形成され、このバリ７ａがリベット４の打ち込みに応じて下方の樹脂部材５内に食い込んでいく。   When the rivet 4 penetrates the metal plate 7, a burr 7 a is formed on the metal plate 7, and this burr 7 a bites into the lower resin member 5 in response to the driving of the rivet 4.

図４で示すように、リベット４の上面が上方の樹脂部材６の上面と面一になるまでリベット４を打ち込むことにより、ピアス４ａはリベットダイス３の凹溝３ｂ内にその一部が収容されるように外側に開き、上方の樹脂部材６および下方の樹脂部材５とピアス４ａの間の摩擦力によって双方の樹脂部材５，６が強固に接続された接続構造１０を形成することができる（第２のステップ）。   As shown in FIG. 4, when the rivet 4 is driven until the upper surface of the rivet 4 is flush with the upper surface of the upper resin member 6, a part of the pierce 4 a is accommodated in the concave groove 3 b of the rivet die 3. Thus, the connection structure 10 in which both the resin members 5 and 6 are firmly connected by the frictional force between the upper resin member 6 and the lower resin member 5 and the pierce 4a can be formed (see FIG. Second step).

接続構造１０の接続強度は、上記するセルフピアスリベットのアンカー効果による接続強度に加えて、下方の樹脂部材５に食い込んだ金属板７のバリ７ａによるアンカー効果が付加されており、さらには、金属板７に対する双方の樹脂部材５，６の溶着強度が付加されて高い接続強度の接続構造１０となっている。   In addition to the above-described connection strength due to the anchor effect of the self-piercing rivet, the connection structure 10 has an anchor effect due to the burr 7a of the metal plate 7 biting into the resin member 5 below. The connection structure 10 with high connection strength is obtained by adding the welding strength of the resin members 5 and 6 to the plate 7.

さらには、金属板７と双方の樹脂部材５，６が溶着していることにより、従来のセルフピアスリベット接続のみの場合には期待し得なかった接続箇所におけるシール性が保証されることになる。   Furthermore, since the metal plate 7 and the both resin members 5 and 6 are welded, the sealing performance at the connection location that could not be expected in the case of the conventional self-piercing rivet connection alone is guaranteed. .

このように、樹脂部材の接続方法の第１の実施の形態は、２つの熱可塑性樹脂からなる樹脂部材５，６をその間に導電性の金属板７を介層させながら重ね合わせて重ね合わせ箇所を形成し、金属板７に通電して金属板７と接する上下の樹脂部材６，５双方の少なくとも金属板７との界面を溶融させて金属板７に溶着する第１のステップと、重ね合わせ箇所の上方からセルフピアスリベット４を打ち込んで最下層の樹脂部材５の内部まで到達させ、溶着と、リベット接続と、セルフピアスリベット４が金属板７を貫通した際にできたバリ７ａが金属板７の下層の樹脂部材５内に食い込んでいること、によって樹脂部材５，６同士を接続する第２のステップからなる接続方法である。   As described above, in the first embodiment of the resin member connecting method, the resin members 5 and 6 made of two thermoplastic resins are overlapped with the conductive metal plate 7 interposed therebetween, and the overlapping portions are overlapped. A first step of energizing the metal plate 7 to melt at least the interface between the upper and lower resin members 6 and 5 in contact with the metal plate 7 and welding to the metal plate 7; A self-piercing rivet 4 is driven from above the portion to reach the inside of the lowermost resin member 5, and a burr 7 a formed when welding, rivet connection, and the self-piercing rivet 4 penetrates the metal plate 7 is a metal plate 7 is a connection method comprising a second step of connecting the resin members 5 and 6 by biting into the lower resin member 5.

（樹脂部材の接続方法の第２の実施の形態）
第１の実施の形態の接続方法以外にも、第１のステップと第２のステップの構成を入れ替えてなる接続方法であってもよい。具体的には、２つの熱可塑性樹脂からなる樹脂部材５，６をその間に導電性の金属板７を介層させながら重ね合わせて重ね合わせ箇所を形成し、重ね合わせ箇所の上方からセルフピアスリベット４を打ち込んで最下層の樹脂部材５の内部まで到達させる第１のステップと、金属板７に通電して金属板７と接する上下の樹脂部材５，６双方の少なくとも金属板７との界面を溶融させて金属板７に溶着させ、リベット接続と、溶着と、セルフピアスリベット４が金属板７を貫通した際にできたバリ７ａが金属板７の下層の樹脂部材５内に食い込んでいること、によって樹脂部材５，６同士を接続する第２のステップからなる接続方法である。 (Second embodiment of resin member connection method)
In addition to the connection method of the first embodiment, a connection method in which the configurations of the first step and the second step are interchanged may be used. Specifically, the resin members 5 and 6 made of two thermoplastic resins are overlapped with a conductive metal plate 7 interposed therebetween to form an overlap portion, and a self-piercing rivet is formed from above the overlap portion. 4 is driven to reach the inside of the lowermost resin member 5, and at least the interface between the upper and lower resin members 5 and 6 in contact with the metal plate 7 by energizing the metal plate 7 with the metal plate 7. It is melted and welded to the metal plate 7, rivet connection, welding, and burrs 7 a formed when the self-piercing rivet 4 penetrates the metal plate 7 are biting into the resin member 5 below the metal plate 7. In this connection method, the resin members 5 and 6 are connected by the second step.

（車両ボディーへの適用例）
図５は、上記接続方法を適用した一つの実施例を説明した図であり、車両ボディーを構成する２つの繊維強化樹脂部材が接続された状態を示す模式図である。 (Application example to vehicle body)
FIG. 5 is a view for explaining one embodiment to which the above connection method is applied, and is a schematic view showing a state where two fiber reinforced resin members constituting the vehicle body are connected.

図示する実施例は、車両ボディーを２枚の繊維強化樹脂部材からなる上方部材６Ａおよび下方部材５Ａとこれらの間に介在する薄い金属板７Ａ、補強部材８から構成するものであり、上方部材６Ａおよび下方部材５Ａ同士、および上方部材６Ａと補強部材８同士がそれぞれ金属板７Ａを間に介在させて上記する接続方法で接続される。なお、同図において図示されるリベット４の端面箇所が上記接続方法で接続された箇所である。   In the illustrated embodiment, the vehicle body is composed of an upper member 6A and a lower member 5A made of two fiber-reinforced resin members, a thin metal plate 7A interposed therebetween, and a reinforcing member 8, and the upper member 6A. The lower members 5A and the upper members 6A and the reinforcing members 8 are connected by the connection method described above with the metal plate 7A interposed therebetween. In addition, the end surface location of the rivet 4 shown in the figure is a location connected by the above connection method.

リベット接続条件としては、パンチによる押し込み力を０．６〜０．８ＭＰａ程度、金属板の加熱温度に関しては、熱可塑性樹脂にポリプロピレンを使用した場合は８５〜１２０℃、熱可塑性樹脂にポリアミド（ＰＡ６）を使用した場合は１５０〜２００℃、ポリアミド（ＰＡ６６）を使用した場合は１９０〜２５０℃程度に調整することができる。なお、金属板７Ａは鉄−クロム−アルミ系の平板を使用し、通電することによってジュール熱を生じるものである。   As rivet connection conditions, the indentation force by the punch is about 0.6 to 0.8 MPa, and the heating temperature of the metal plate is 85 to 120 ° C. when polypropylene is used as the thermoplastic resin, and polyamide (PA6) is used as the thermoplastic resin. ) Can be adjusted to 150 to 200 ° C., and polyamide (PA66) can be adjusted to about 190 to 250 ° C. The metal plate 7A uses an iron-chromium-aluminum plate and generates Joule heat when energized.

図示する車両ボディーは、軽量かつ高強度の２枚の繊維強化樹脂部材が接続されて構成されている。   The illustrated vehicle body is configured by connecting two fiber-reinforced resin members that are lightweight and have high strength.

そして、繊維強化樹脂部材同士の接続にセルフピアスリベットが適用されているものの、接続箇所のシール性が保証され、さらに、接続箇所の接続強度は、セルフピアスリベット接続による強度以外にも、金属板のバリが樹脂部材内に食い込んでなる接続強度や金属板に対する樹脂部材の溶着強度が付加された極めて高い接続強度を有していることから、高い接続強度を有し、シール性に優れ、軽量かつ高強度の車両ボディーとなっている。   And although the self-piercing rivet is applied to the connection between the fiber reinforced resin members, the sealing property of the connecting portion is guaranteed, and the connection strength of the connecting portion is not limited to the strength due to the self-piercing rivet connection. Because it has a very high connection strength with the addition of the connection strength that the burr bites into the resin member and the welding strength of the resin member to the metal plate, it has high connection strength, excellent sealing properties, and lightweight And it is a high-strength vehicle body.

[本発明の接続方法で接続された２つの樹脂部材（実施例）と従来の接続方法で接続された２つの樹脂部材（比較例）それぞれの接続箇所のせん断引張り破断強度を測定した実験とその結果]
本発明者等は、２枚の繊維強化樹脂部材の間に金属板を介在させて既述する実施の形態２の接続方法で接続した試験片（実施例）と、２枚の繊維強化樹脂部材をセルフピアスリベット接続のみで接続した試験片（比較例）を用意し、それぞれを引張試験機にクランプして引張速度５ｍｍ／ｍｉｎで引っ張った際のせん断引張り破断強度を測定した。この測定結果を図６に示している。 [Experiment of measuring shear tensile breaking strength of each of two resin members connected by the connection method of the present invention (Example) and two resin members connected by a conventional connection method (Comparative Example) result]
The inventors of the present invention have provided a test piece (example) connected by the connection method of the second embodiment described above with a metal plate interposed between two fiber reinforced resin members, and two fiber reinforced resin members. The test piece (comparative example) which connected only by the self-piercing rivet connection was prepared, each was clamped to the tensile testing machine, and the shear tensile breaking strength at the time of pulling at 5 mm / min was measured. The measurement results are shown in FIG.

図６より、比較例に比して実施例のせん断引張り強度は２倍程度も向上することが実証されている。これは、実施例の接続強度がセルフピアスリベット接続によるもののほかに、溶着による効果、金属板のバリが一方の繊維強化樹脂材内に食い込んでいることによるアンカー効果によるものである。なお、既述する実施の形態１の方法によっても実施の形態２と同様の効果が得られることが本発明者等によって特定されている。   FIG. 6 demonstrates that the shear tensile strength of the example is improved by about twice as compared with the comparative example. This is because the connection strength of the embodiment is due to the effect of welding and the anchor effect due to the burrs of the metal plate biting into one of the fiber reinforced resin materials in addition to the self-piercing rivet connection. It has been specified by the present inventors that the same effects as those of the second embodiment can be obtained by the method of the first embodiment described above.

以上、本発明の実施の形態を図面を用いて詳述してきたが、具体的な構成はこの実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲における設計変更等があっても、それらは本発明に含まれるものである。   The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. They are also included in the present invention.
