Description
(A)まず、2つの部品(第1部品1,第2部品2)を重ね合せ、部品間の隙間形状を測定する。
(B)次に、隙間形状に合わせてソリッド材3を機械加工して、シム4を作成する。
(C)シム4を隙間5に挿入し、接合面間の隙間を埋める。
まず、本実施形態に係る組立方法で組み立てられた接合部材について説明する。接合部材は、重ね合せられた複数の部材と、前記複数の部材間を埋めるよう存在するシムと、を備えている。また、接合部材は、重ね合せられた複数の部材を締結する締結部材を備えている。
重ね合せた第1部品15と第2部品16との間にある空隙17に、基材20aを挿入する(図3(A)参照)。挿入場所については、製造時の形状公差から発生すると想定される空隙量を見積もってく。見積もった空隙量に合わせて多層構造織物のサイズ等を選択し、挿入する。想定する空隙量については、設計段階であらかじめ想定した空隙量も含む。基材20aは、膨張変化させる前のものであり、空隙17内への挿入が容易である。
次に、空隙17に樹脂を充填し、基材に樹脂18を含浸させる(図3(B)参照)。樹脂18の充填は、作業性のために必要なクリアランスを確保できるスペーサーを設置し、その間に基材を挿入して樹脂を注入することで実施できる。これにより空隙17内の基材20aに樹脂18を含浸させるとともに空隙17を埋める。図3(B)では樹脂18を含浸させている途中の様子を示している。
基材を所定温度に加熱して厚さ方向に膨張変化させる。加熱は、樹脂18の充填と同時または充填前後のいずれかのタイミングで実施され得る。例えば、充填する樹脂の温度が所定温度以上であれば別途加熱しなくても、樹脂充填と同時に基材を膨張変化させることができる。例えば、充填する樹脂の温度が所定温度未満である場合には、樹脂の充填が終了した後に、基材を加熱すればよい。
基材20aを膨張させた後、樹脂18を硬化させて樹脂18’とする(図3(C)参照)。樹脂18にエポキシ樹脂などの熱硬化性樹脂を用いた場合、樹脂18が硬化温度(例えば90℃から120℃)となるよう第1部品15および第2部品16をヒータマット等で覆い加熱すればよい。樹脂18にPEEKなどの熱可塑性樹脂を用いた場合、樹脂18が硬化する温度に達するように冷却する。冷却は、放冷でもよいし、スポットクーラーなどの冷却手段を用いて積極的に実施してもよい。
樹脂18を硬化させた後、締結部材で第1部品15と第2部品16を締結する。例えば、リベット、ボルト等を用いる。
本実施形態に係る組立方法で組み立てられた接合部材の構成は、第1実施形態と同様である。本実施形態に係る組立方法は、基材を膨張変化させるタイミングが第1実施形態と異なる。図4に、本実施形態に係る接合部材の組立方法のフロー図を示す。
基材を所定温度に加熱して厚さ方向に膨張変化させる(図4(A)参照)。図4(A)は、膨張変化後の基材20bの縦断面を示している。加熱は、ヒーター、ハンドドライヤーまたはオーブンなどを用いて実施され得る。
重ね合せた第1部品15と第2部品16との間(合せ面側)にある空隙17に、膨張変化させた基材20bを挿入する(図4(A)および図4(B)参照)。
空隙17に樹脂18を充填する(図4(C)参照)。これにより空隙17内の基材20bに樹脂18を含浸させるとともに空隙17を埋める。図4(C)では樹脂18を含浸させている途中の様子を示している。
樹脂18の含浸終了後、第1実施形態と同様に樹脂18を硬化させる(図4(D)参照)。
第1実施形態と同様に、締結部材で第1部品15と第2部品16を締結する。
