Description
図4には、航空機の翼の前方スパーが示される。スパーは、ウェブ10、上方フランジ11、及び下方フランジ(図示せず)を具備する。スパーは、ウェブ10がフランジ11と交わる湾曲部(radius portion)10aを有する。積層複合材スキン12が、上方フランジ11に取り付けられ、且つ翼ボックス(翼の主要な構造要素)の上側境界を形成すべくスパーの後方に延在する。また、スキン12は、図4に示されるように、僅かにスパーの前方に突き出る。
スキン12は、図4に示されている外側面13と、図7に示されている内側面14とを有する。
・エッジプロテクター22が、相対的に厚い端部から相対的に薄い縁部へと次第に細くなる楔形で予め形成される。エッジプロテクター22は、単方向の押出複合材料、ゴムから、またはエポキシ樹脂を含侵したカーボンファイバーによって予め形成され、形作りすべく引き抜き成形されてもよい。好ましくは、エッジプロテクターは、カーボンファイバー及びエポキシ樹脂が混合され且つ所望の断面形状を備えたダイを通してローラーによって引き抜かれる引き抜き成形処理によって予め形成される。ダイはエポキシ樹脂を硬化、または部分的に硬化すべく加熱せしめられるので、エッジプロテクター22がその形状を保持する。
・エッジプロテクター22は、図示されるように、エッジプロテクター22の厚い端部が銅フィルムの段部に接触した状態で、銅フィルム20上に配置される。エッジプロテクター22の傾斜面23は成形型上に載置される前または後に一片のフィルム接着剤FM300(図示せず)に取り付けられる。
・「プリプレグ」の第一層24が、成形型上に載置され、フィルム接着剤に付着する。「プリプレグ」の第一層24は、エポキシ樹脂マトリックスを含侵したカーボンファイバーの一方向の配列を有する。
・真空バッグ(図示せず)が、剥離フィルムのような他の要素と随意に組み合わせられて、最終層25上に載置される。
・真空バッグと成形型との間の空間はオートクレーブ内で真空引きにされ、同時にオートクレーブはプリプレグ及びエッジプロテクター22が完全に硬化されるようにエポキシ樹脂の硬化温度よりも高い温度に加熱される。
・図7に示されるように、真空バッグ等は除去され、硬化したスキン12が残る。
