Abstract
【解決手段】本発明のFRP接合構造は、少なくとも1つのFRP部材を含む複数の部材(右半体3aおよび左半体3b)が重ね合わせられて接着剤4を介して相互に接合されたFRP接合構造2Aにおいて、接着剤4が未硬化の状態で、最も表側に配置された部材(右半体3a)から打ち込まれたセルフピアスリベット6の先端6cが最も裏側に配置された部材(左半体3b)内に留まっているように構成されている。
【選択図】図2
Description
また、他のFRP接合構造としては、ボルト等の締結具を使用したものが知られている(例えば、特許文献2参照)。このFRP接合構造は、FRP部材に予め下孔を形成した後に、この下孔に挿通した締結具を介してFRP部材と所定の部材とを接合することによって得られる。
また、このFRP接合構造は、複数の部材がセルフピアスリベットで締結されているので、たとえ接着剤層内やFRP部材自体の層間に亀裂が発生した場合であってもセルフピアスリベットが亀裂の伝播を食い止める。
また、このFRP接合構造では、セルフピアスリベットが、最も表側に配置された部材から最も裏側に配置された部材に向かって打ち込まれることとなるので、ボルト等を使用した従来のFRP接合構造と異なって、FRP部材に下孔加工を施す必要がない。また、セルフピアスリベットは、その先端が最も裏側に配置された部材内に留まっており、最も裏側に配置された部材を突き抜けることなくこれら部材同士を締結する。
また、このFRP接合構造は、ボルト等を使用した従来のFRP接合構造と異なって、接合位置のバラツキ(ずれ)を吸収するためのクリアランスホール(バカ孔)をFRP部材に設ける必要がないので、接合部分におけるFRP部材と所定の部材との接触面積が低減することがない。
セルフピアスリベット6は、公知の構造を有するものでよく、例えば、図2に示すように、後記する打ち込みツール7a(図3(c)参照)を受け止める頭部6aと、後記するダイ7d(図3(c)参照)によって座屈変形して展開する略円筒状の脚部6bとを備えている。このセルフピアスリベット6は、上市品であってもよい。そして、セルフピアスリベット6は、展開したその先端6cが左半体3b内に留まっている。
本実施形態での薄層5は、樹脂で形成されており、左半体3bの裏側の面に密着するように設けられた樹脂フィルムであってもよいし、左半体3bの裏側の面に樹脂塗料を塗布することで形成された塗膜であってもよい。
図2に示すFRP接合構造2Aは、接着剤4を介して重ね合わせられた左右半体3a,3b同士がセルフピアスリベット6で締結されているので、接着剤のみを使用した従来のFRP接合構造と異なって、接着剤4が硬化状態または半硬化状態になるまで左右半体3a,3b同士を固定しなくてもよい。したがって、FRP接合構造2Aは、治具に拘束される時間を要しないのでその生産性が向上する。そして、FRP接合構造2Aは、治具に拘束されることがないので、このFRP接合構造2Aが適用される最終製品(本実施形態では小型航空機)を製造するための次工程に直ちに移行させることができる。つまり、FRP接合構造2Aは、最終製品の生産性をも向上させることができる。
つまり、この製造方法によれば、接着剤4が未硬化の状態で左右半体3a,3bに打ち込まれたセルフピアスリベット6が左右半体3a,3b同士を締結するので、接着剤4が未硬化であっても左右半体3a,3b同士がずれることはない。したがって、この製造方法では、接着剤4が未硬化の状態であっても左右半体3a,3b同士を固定する治具を必要としないので、FRP接合構造2Aの生産性を向上させることができる。
前記実施形態では、右半体3aと左半体3bとの2部材が相互に接合されるFRP接合構造2Aを例示したが、本発明は接合される部材の数に特に制限はなく、次のようなFRP接合構造であってもよい。図4は、他の実施形態に係るFRP接合構造を示す断面図である。なお、この他の実施形態において前記実施形態と同様の構成要素については同じ符号を付して、その詳細な説明は省略する。
