Description

本発明は、ＦＲＰ製の板材などを接合するのに適したＦＲＰ製部材の接合構造に関する。   The present invention relates to a FRP member joining structure suitable for joining FRP plate members and the like.

ＦＲＰ（Fiber Reinforced Plastic）と称される繊維強化プラスチックは、金属材料と比較して剛性や強度に遜色なく、軽量かつ耐久性（腐食性）に優れていることから、様々な分野で各種部材等への適用が検討されている。

FIG.

以下、図面を参照して、本発明に係るＦＲＰ製部材の接合構造の実施形態について詳細に説明する。但し、以下に述べる実施形態には、本発明を実施するために技術的に好ましい種々の限定が付されているが、本発明の範囲を以下の実施形態及び図示例に限定するものではない。
本実施形態では、少なくとも２つのＦＲＰ製部材が接合されてなるＦＲＰ製部材の接合構造について説明する。 Hereinafter, with reference to drawings, embodiment of the joining structure of the member made from FRP concerning the present invention is described in detail. However, the embodiments described below are given various technically preferable limitations for carrying out the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.
In this embodiment, an FRP member joining structure in which at least two FRP members are joined will be described.

（実施形態１）
実施形態１のＦＲＰ製部材の接合構造１００は、図１（ａ）（ｂ）に示すように、添接板１３を介して第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合したものであり、その接合にＦＲＰ製ボルト２０と樹脂製の充填部材３０を用いたものである。 (Embodiment 1)
The FRP member joining structure 100 of the first embodiment joins the first FRP member 11 and the second FRP member 12 via the attachment plate 13 as shown in FIGS. The FRP bolt 20 and the resin filling member 30 are used for the joining.

第１のＦＲＰ製部材１１及び第２のＦＲＰ製部材１２は、ＦＲＰ（Fiber Reinforced Plastic）を材料に成型された部材であり、同一形状の部材を金属材料で成型するよりも軽量化を図っている。
また、添接板１３もＦＲＰを材料に成型されたＦＲＰ製部材である。
これら第１のＦＲＰ製部材１１、第２のＦＲＰ製部材１２、添接板１３にはそれぞれ、ＦＲＰ製ボルト２０を挿通させる小孔１１ａ、１２ａ、１３ａが形成されている。 The first FRP member 11 and the second FRP member 12 are members formed from FRP (Fiber Reinforced Plastic) as a material, and are designed to be lighter than molding a member having the same shape from a metal material. Yes.
Further, the contact plate 13 is also an FRP member formed by using FRP as a material.
Small holes 11 a, 12 a, and 13 a through which the FRP bolts 20 are inserted are formed in the first FRP member 11, the second FRP member 12, and the attachment plate 13, respectively.

ＦＲＰ製ボルト２０は、ＦＲＰを材料に成型された接続部材である。
このＦＲＰ製ボルト２０とともに用いるナット２１とワッシャー２２もＦＲＰを材料に成型された部材である。 The FRP bolt 20 is a connection member formed of FRP as a material.
A nut 21 and a washer 22 used together with the FRP bolt 20 are members formed of FRP.

充填部材３０は、ＦＲＰ製部材の小孔１１ａ、１２ａ、１３ａの内壁面と、ＦＲＰ製ボルト２０の間に充填されている樹脂材料からなる部材である。
この充填部材３０には、例えば、熱硬化型樹脂、紫外線硬化型樹脂、湿気硬化型樹脂などを用いることができる。 The filling member 30 is a member made of a resin material filled between the inner wall surfaces of the small holes 11 a, 12 a, and 13 a of the FRP member and the FRP bolt 20.
For the filling member 30, for example, a thermosetting resin, an ultraviolet curable resin, a moisture curable resin, or the like can be used.

そして、第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合する場合、図１（ａ）に示すように、互いの端部を突き合わせるように並べた第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を一対の添接板１３で挟み込み、一対の添接板１３の小孔１３ａと第１のＦＲＰ製部材１１の小孔１１ａを位置合わせし、重なった小孔（１３ａ、１１ａ）にＦＲＰ製ボルト２０を連通させる。同様に、一対の添接板１３の小孔１３ａと第２のＦＲＰ製部材１２の小孔１２ａを位置合わせし、重なった小孔（１３ａ、１２ａ）にＦＲＰ製ボルト２０を連通させる。   When the first FRP member 11 and the second FRP member 12 are joined, as shown in FIG. 1 (a), the first FRP members 11 arranged so as to abut each other's ends. And the second FRP member 12 are sandwiched between a pair of attachment plates 13, the small holes 13a of the pair of attachment plates 13 and the small holes 11a of the first FRP member 11 are aligned, and the overlapping small holes ( The FRP bolt 20 is communicated with 13a, 11a). Similarly, the small holes 13a of the pair of attachment plates 13 and the small holes 12a of the second FRP member 12 are aligned, and the FRP bolts 20 are communicated with the overlapping small holes (13a, 12a).

次いで、第１のＦＲＰ製部材１１側の小孔（１３ａ、１１ａ）の内壁面とＦＲＰ製ボルト２０の間と、第２のＦＲＰ製部材１２側の小孔（１３ａ、１２ａ）の内壁面とＦＲＰ製ボルト２０の間に、それぞれ充填材を充填し、所定の硬化処理を施して充填部材３０を形成する。
例えば、充填材として熱硬化型樹脂を用いた場合、その充填材を充填した後、所定の加熱処理による硬化処理を施して充填部材３０を形成する。
また、充填材として紫外線硬化型樹脂を用いた場合、その充填材を充填した後、所定の紫外線照射処理による硬化処理を施して充填部材３０を形成する。
また、充填材として湿気硬化型樹脂を用いた場合、その充填材を充填した後、所定の加湿処理による硬化処理を施して充填部材３０を形成する。
こうした硬化処理によって充填部材３０を形成した後に、ＦＲＰ製ボルト２０にナット２１を螺着すれば、図１（ｂ）に示すように、第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合してなるＦＲＰ製部材の接合構造１００が組み上がる。 Next, between the inner wall surface of the small hole (13a, 11a) on the first FRP member 11 side and the FRP bolt 20 and the inner wall surface of the small hole (13a, 12a) on the second FRP member 12 side A filler is filled between the FRP bolts 20 and a predetermined curing process is performed to form the filling member 30.
For example, when a thermosetting resin is used as the filler, the filling member 30 is formed by performing a curing process by a predetermined heat treatment after filling the filler.
When an ultraviolet curable resin is used as the filler, the filler 30 is filled and then subjected to a curing process by a predetermined ultraviolet irradiation process to form the filling member 30.
When a moisture curable resin is used as the filler, the filler 30 is filled and then subjected to a curing process by a predetermined humidification process to form the filling member 30.
If the nut 21 is screwed onto the FRP bolt 20 after the filling member 30 is formed by such a curing process, the first FRP member 11 and the second FRP member 12 are formed as shown in FIG. The FRP member bonding structure 100 is assembled.

なお、ＦＲＰ製部材の小孔の内壁面とＦＲＰ製ボルト２０の間に充填材を充填した後、ＦＲＰ製ボルト２０にナット２１を螺着してから所定の硬化処理を施して充填部材３０を形成する手順で、ＦＲＰ製部材の接合構造１００を組み上げるようにしてもよい。
充填材として熱硬化型樹脂を用いた場合、ＦＲＰ製ボルト２０にナット２１を螺着した後でも、充填材に加熱処理による硬化処理を施すことができる。
また、充填材として湿気硬化型樹脂を用いた場合、ＦＲＰ製ボルト２０にナット２１を螺着した後でも、毛細管現象を利用して充填材に加湿処理による硬化処理を施すことができる。
また、充填材として紫外線硬化型樹脂、特にエポキシ系カチオン重合タイプの紫外線硬化型樹脂を用いた場合、紫外線照射量が僅かであっても硬化反応が継続して進行するので、ＦＲＰ製ボルト２０にナット２１を螺着した後でも、充填材の硬化処理を継続して行うことができる。 After filling the filler between the inner wall surface of the small hole of the FRP member and the FRP bolt 20, the nut 21 is screwed onto the FRP bolt 20, and then a predetermined curing process is performed to fix the filling member 30. You may make it assemble the joining structure 100 of the member made from FRP in the procedure to form.
When a thermosetting resin is used as the filler, the filler can be cured by heat treatment even after the nut 21 is screwed onto the FRP bolt 20.
Further, when a moisture curable resin is used as the filler, the filler can be cured by a humidification process using the capillary phenomenon even after the nut 21 is screwed onto the FRP bolt 20.
Further, when an ultraviolet curable resin, particularly an epoxy cationic polymerization type ultraviolet curable resin is used as the filler, the curing reaction continues even if the amount of ultraviolet irradiation is small. Even after the nut 21 is screwed, the curing process of the filler can be continued.

このように、実施形態１のＦＲＰ製部材の接合構造１００は、第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合するのに、ＦＲＰ製の添接板１３、ＦＲＰ製ボルト２０、ＦＲＰ製のナット２１やワッシャー２２、樹脂製の充填部材３０を用いており、経年劣化して腐食するおそれのある金属製の部材を用いていない。
このようなＦＲＰ製部材の接合構造１００であれば、ＦＲＰの材料特性を発揮させることができ、耐久性に優れた接合構造とすることができる。 As described above, the FRP member joining structure 100 according to the first embodiment is configured to join the first FRP member 11 and the second FRP member 12 to the FRP attachment plate 13 and the FRP bolt 20. FRP nuts 21 and washers 22 and resin filling members 30 are used, and metal members that are likely to deteriorate over time and corrode are not used.
With such an FRP member bonding structure 100, the material characteristics of FRP can be exhibited, and a bonding structure with excellent durability can be obtained.

特に、ＦＲＰ製部材の小孔（１１ａ、１２ａ、１３ａ）の内壁面とＦＲＰ製ボルト２０の間に樹脂製の充填部材３０を設けて「支圧接合」による接合構造としたことで、接合部分の剪断耐力を向上させて、ＦＲＰ製部材の接合構造１００の構造安定性を向上させている。
こうすることで、本実施形態のＦＲＰ製部材の接合構造１００の耐久性をより一層向上させることができる。 In particular, by providing a resin filling member 30 between the inner wall surface of the small hole (11a, 12a, 13a) of the FRP member and the FRP bolt 20, a joining structure by "support pressure joining" is obtained. This improves the structural stability of the joining structure 100 of FRP members.
By carrying out like this, durability of the joining structure 100 of the member made from FRP of this embodiment can be improved further.

これに対し、ＦＲＰ製部材の小孔の内壁面とＦＲＰ製ボルト２０の間に樹脂製の充填部材３０を設けていない接続構造、つまり、既存のＦＲＰ製のボルトとナットを用いた螺着のみによって、添接板１３を介して第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合してなる接続構造は「摩擦接合」となる。
高耐久性を有するＦＲＰ製のボルトやナットであっても、雄ネジや雌ネジのネジ山部分にはＦＲＰの強化材である繊維材料（例えばガラス繊維や炭素繊維）がほとんど含まれておらず、そこが弱点箇所になるので、単にＦＲＰ製のボルトやナットを用いた接続構造を組み上げても、その構造安定性は向上しない。 On the other hand, a connecting structure in which the resin filling member 30 is not provided between the inner wall surface of the small hole of the FRP member and the FRP bolt 20, that is, only screwing using an existing FRP bolt and nut. Thus, the connection structure formed by joining the first FRP member 11 and the second FRP member 12 through the attachment plate 13 is “friction joining”.
Even FRP bolts and nuts with high durability contain almost no fiber material (for example, glass fiber or carbon fiber) that is a reinforcing material for FRP in the threaded portion of male and female screws. Since this becomes a weak spot, even if a connection structure using FRP bolts and nuts is simply assembled, the structural stability is not improved.

本実施形態１のＦＲＰ製部材の接合構造１００は、ＦＲＰ製部材（１１、１２、１３、）を接合するのにＦＲＰ製ボルト２０やＦＲＰ製のナット２１を用いることに加え、ＦＲＰ製部材の小孔（１１ａ、１２ａ、１３ａ）の内壁面とＦＲＰ製ボルト２０の間に樹脂製の充填部材３０を形成したことにより、その構造安定性を向上させ、耐久性に優れた良好な接合構造にすることを可能にしたのである。   In addition to using the FRP bolt 20 and the FRP nut 21 to join the FRP members (11, 12, 13,), the FRP member joining structure 100 of the first embodiment includes the FRP member By forming the resin filling member 30 between the inner wall surface of the small holes (11a, 12a, 13a) and the FRP bolt 20, the structural stability is improved, and a good joining structure with excellent durability is achieved. It made it possible to do.

なお、上記実施形態１では、位置合わせした添接板１３の小孔１３ａと第１のＦＲＰ製部材１１及び第２のＦＲＰ製部材１２の小孔１１ａ、１２ａにＦＲＰ製ボルト２０を連通させた後、ＦＲＰ製部材の小孔の内壁面とＦＲＰ製ボルト２０の間に充填材を充填したが、位置合わせした各小孔（１１ａ、１２ａ、１３ａ）内に予め充填材を充填しておき、そこへＦＲＰ製ボルト２０を連通させるように取り付けてもよい。
この手順であっても、ＦＲＰ製部材の小孔の内壁面とＦＲＰ製ボルト２０の間に充填材を充填することができ、充填部材３０を設けることができる。 In the first embodiment, the FRP bolts 20 are communicated with the small holes 13 a of the aligned attachment plate 13 and the small holes 11 a and 12 a of the first FRP member 11 and the second FRP member 12. After that, the filler was filled between the inner wall surface of the small hole of the FRP member and the FRP bolt 20, but the filler was filled in advance in each of the aligned small holes (11a, 12a, 13a), You may attach so that the FRP bolt 20 may be connected there.
Even in this procedure, the filler can be filled between the inner wall surface of the small hole of the FRP member and the FRP bolt 20, and the filler member 30 can be provided.

なお、本発明は上記実施形態に限られるものではない。
例えば、図２に示すように、第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合するのに添接板１３を用いず、第１のＦＲＰ製部材１１の小孔１１ａと第２のＦＲＰ製部材１２の小孔１２ａを位置合わせし、そこへＦＲＰ製ボルト２０を連通させてなるＦＲＰ製部材の接合構造１００であってもよい。勿論、ＦＲＰ製部材の小孔（１１ａ、１２ａ）の内壁面とＦＲＰ製ボルト２０の間には樹脂製の充填部材３０を配設している。
このＦＲＰ製部材の接合構造１００であっても、ＦＲＰの材料特性を発揮させ、耐久性に優れた接合構造とすることができる。 The present invention is not limited to the above embodiment.
For example, as shown in FIG. 2, the joining plate 13 is not used to join the first FRP member 11 and the second FRP member 12, and the small holes 11a of the first FRP member 11 The FRP member joining structure 100 may be formed by aligning the small holes 12a of the two FRP members 12 and communicating the FRP bolts 20 therewith. Of course, a resin filling member 30 is disposed between the inner wall surface of the small hole (11a, 12a) of the FRP member and the FRP bolt 20.
Even this FRP member bonding structure 100 can exhibit the material characteristics of FRP and provide a bonding structure with excellent durability.

（実施形態２）
次に、本発明に係るＦＲＰ製部材の接合構造の実施形態２について説明する。なお、実施形態１と同一部分には同符号を付し、異なる部分についてのみ説明する。 (Embodiment 2)
Next, a second embodiment of the FRP member joining structure according to the present invention will be described. The same parts as those in the first embodiment are denoted by the same reference numerals, and only different parts will be described.

実施形態２のＦＲＰ製部材の接合構造１００は、図３（ａ）（ｂ）、図４（ａ）（ｂ）に示すように、添接板１３を介して第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合したものであり、その接合にＦＲＰ製リベット４０を用いたものである。   The FRP member joining structure 100 according to the second embodiment includes the first FRP member 11 and the first FRP member 11 via an attachment plate 13, as shown in FIGS. The second FRP member 12 is joined, and an FRP rivet 40 is used for the joining.

ＦＲＰ製リベット４０は、ＦＲＰを材料に成型された接続部材である。
このＦＲＰ製リベット４０を構成するＦＲＰのプラスチックには、例えば、熱硬化型樹脂、紫外線硬化型樹脂、湿気硬化型樹脂などの硬化性樹脂を採用している。 The FRP rivet 40 is a connecting member formed of FRP as a material.
As the FRP plastic constituting the FRP rivet 40, for example, a curable resin such as a thermosetting resin, an ultraviolet curable resin, or a moisture curable resin is employed.

そして、第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合する場合、図３（ａ）、図４（ａ）に示すように、互いの端部を突き合わせるように並べた第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を一対の添接板１３で挟み込み、一対の添接板１３の小孔１３ａと第１のＦＲＰ製部材１１の小孔１１ａを位置合わせし、重なった小孔（１３ａ、１１ａ）にＦＲＰ製リベット４０を連通させる。同様に、一対の添接板１３の小孔１３ａと第２のＦＲＰ製部材１２の小孔１２ａを位置合わせし、重なった小孔（１３ａ、１２ａ）にＦＲＰ製リベット４０を連通させる。   When the first FRP member 11 and the second FRP member 12 are joined, as shown in FIG. 3A and FIG. 4A, the first FRP member 11 and the second FRP member 12 are arranged so as to abut each other. The first FRP member 11 and the second FRP member 12 are sandwiched between a pair of attachment plates 13, and the small holes 13a of the pair of attachment plates 13 and the small holes 11a of the first FRP member 11 are aligned. The FRP rivet 40 is communicated with the small holes (13a, 11a) overlapped. Similarly, the small holes 13a of the pair of attachment plates 13 and the small holes 12a of the second FRP member 12 are aligned, and the FRP rivets 40 are communicated with the overlapping small holes (13a, 12a).

次いで、図３（ｂ）、図４（ｂ）に示すように、ＦＲＰ製リベット４０をかしめ、そのＦＲＰ製リベット４０がＦＲＰ製部材の小孔（１１ａ、１２ａ）の内壁面に密着するよう変形させる。なお、このＦＲＰ製リベット４０は、粘土様の変形性を有している。
図３（ａ）に示した断面視略Ｔ字状を呈するＦＲＰ製リベット４０の場合、その一端部を加圧してかしめて、小孔（１１ａ、１２ａ）の内壁面に密着させるように変形させて締結する。
図４（ａ）に示した断面視略Ｉ字状を呈するＦＲＰ製リベット４０の場合、その両端部を加圧してかしめて、小孔（１１ａ、１２ａ）の内壁面に密着させるように変形させて締結する。
このようにＦＲＰ製リベット４０は、ＦＲＰ製部材の小孔（１１ａ、１２ａ）の内壁面全体に密着するよう形成されている。 Next, as shown in FIG. 3B and FIG. 4B, the FRP rivet 40 is caulked, and the FRP rivet 40 is deformed so as to be in close contact with the inner wall surface of the small holes (11a, 12a) of the FRP member. Let The FRP rivet 40 has clay-like deformability.
In the case of the FRP rivet 40 having a substantially T-shaped cross-sectional view shown in FIG. 3A, one end of the FRP rivet 40 is pressurized and crimped so as to be in close contact with the inner wall surface of the small holes (11a, 12a). And conclude.
In the case of the FRP rivet 40 having a substantially I shape in cross section shown in FIG. 4A, both ends thereof are pressed and caulked to be deformed so as to be in close contact with the inner wall surfaces of the small holes (11a, 12a). And conclude.
Thus, the FRP rivet 40 is formed so as to be in close contact with the entire inner wall surface of the small hole (11a, 12a) of the FRP member.

そして、ＦＲＰ製部材の小孔（１１ａ、１２ａ）の内壁面に密着させたＦＲＰ製リベット４０に所定の硬化処理を施して、そのＦＲＰ製リベット４０を硬化させる。
例えば、熱硬化型樹脂を採用したＦＲＰ製リベット４０の場合、そのＦＲＰ製リベット４０を小孔（１１ａ、１２ａ）の内壁面に密着させた後、所定の加熱処理による硬化処理を施してＦＲＰ製リベット４０を硬化させる。
また、紫外線硬化型樹脂を採用したＦＲＰ製リベット４０の場合、そのＦＲＰ製リベット４０を小孔（１１ａ、１２ａ）の内壁面に密着させた後、所定の紫外線照射処理による硬化処理を施してＦＲＰ製リベット４０を硬化させる。
また、湿気硬化型樹脂を採用したＦＲＰ製リベット４０の場合、そのＦＲＰ製リベット４０を小孔（１１ａ、１２ａ）の内壁面に密着させた後、所定の加湿処理による硬化処理を施してＦＲＰ製リベット４０を硬化させる。
こうした硬化処理によってＦＲＰ製リベット４０を硬化させれば、図３（ｂ）、図４（ｂ）に示すように、第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合してなるＦＲＰ製部材の接合構造１００が組み上がる。 Then, the FRP rivet 40 that is in close contact with the inner wall surface of the small hole (11a, 12a) of the FRP member is subjected to a predetermined curing process to cure the FRP rivet 40.
For example, in the case of an FRP rivet 40 employing a thermosetting resin, the FRP rivet 40 is brought into close contact with the inner wall surface of the small holes (11a, 12a), and then subjected to a curing process by a predetermined heat treatment to be made of FRP. The rivet 40 is cured.
Further, in the case of the FRP rivet 40 using an ultraviolet curable resin, the FRP rivet 40 is brought into close contact with the inner wall surface of the small hole (11a, 12a), and then subjected to a curing process by a predetermined ultraviolet irradiation process. The rivet 40 is cured.
Further, in the case of the FRP rivet 40 employing a moisture curable resin, the FRP rivet 40 is brought into close contact with the inner wall surface of the small holes (11a, 12a), and then subjected to a curing process by a predetermined humidification process to be made of FRP. The rivet 40 is cured.
If the FRP rivet 40 is cured by such a curing process, the first FRP member 11 and the second FRP member 12 are joined as shown in FIGS. 3B and 4B. An FRP member joining structure 100 is assembled.

なお、ここではＦＲＰ製リベット４０をかしめて、ＦＲＰ製部材の小孔（１１ａ、１２ａ）の内壁面に密着させるように変形させた後に、所定の硬化処理を施したが、ＦＲＰ製リベット４０の加圧変形と所定の硬化処理をほぼ同時進行するようにして、ＦＲＰ製部材の接合構造１００を組み上げるようにしてもよい。   Here, the FRP rivet 40 is crimped and deformed so as to be in close contact with the inner wall surfaces of the small holes (11a, 12a) of the FRP member, and then subjected to a predetermined curing process. The FRP member joining structure 100 may be assembled so that the pressure deformation and the predetermined curing process proceed substantially simultaneously.

このように、実施形態２のＦＲＰ製部材の接合構造１００は、第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合するのに、ＦＲＰ製の添接板１３、ＦＲＰ製リベット４０を用いており、経年劣化して腐食するおそれのある金属製の部材を用いていない。
特に、ＦＲＰ製リベット４０をかしめて、ＦＲＰ製部材の小孔（１１ａ、１２ａ）の内壁面に密着させて硬化させて「支圧接合」による接合構造としたことで、ＦＲＰ製部材の接合構造１００の構造安定性を向上させている。

It does not use metal members that are likely to deteriorate over time and corrode.
In particular, the FRP rivet 40 is caulked and adhered to the inner wall surface of the small hole (11a, 12a) of the FRP member to be cured to form a joint structure by “supporting joint”. 100 structural stability is improved.
With such an FRP member bonding structure 100, the material characteristics of FRP can be exhibited, and a bonding structure with excellent durability can be obtained.

なお、本発明は上記実施形態に限られるものではない。
例えば、図５に示すように、第１のＦＲＰ製部材１１と第２のＦＲＰ製部材１２を接合するのに添接板１３を用いず、第１のＦＲＰ製部材１１の小孔１１ａと第２のＦＲＰ製部材１２の小孔１２ａを位置合わせし、そこへＦＲＰ製リベット４０を連通させてなるＦＲＰ製部材の接合構造１００であってもよい。勿論、ＦＲＰ製リベット４０はかしめられ、ＦＲＰ製部材の小孔（１１ａ、１２ａ）の内壁面に密着しており、硬化処理が施されている。
このＦＲＰ製部材の接合構造１００であっても、ＦＲＰの材料特性を発揮させ、耐久性に優れた接合構造とすることができる。 The present invention is not limited to the above embodiment.
For example, as shown in FIG. 5, the joining plate 13 is not used to join the first FRP member 11 and the second FRP member 12, and the small holes 11a of the first FRP member 11 and the first The FRP member joining structure 100 may be formed by aligning the small holes 12a of the two FRP members 12 and communicating the FRP rivets 40 therewith. Of course, the FRP rivet 40 is caulked and is in close contact with the inner wall surfaces of the small holes (11a, 12a) of the FRP member, and is subjected to a curing process.
Even this FRP member bonding structure 100 can exhibit the material characteristics of FRP and provide a bonding structure with excellent durability.

以上のように、本発明にかかるＦＲＰ製部材の接合構造１００は、耐久性に優れている。
