Description
a)その部品が大きな厚みを有し(一般的に>10mm)、少なくとも部分的に平坦でない、または
b)その部品が周囲の部材よりも十分に厚いパッドアップ(盛り上がり)領域を包含している。
複合材料の層から物品を形成する方法は、米国特許出願公開第2002/0012591号に記載されている。ツールと膜との相互間に不完全な真空を発生させている間、膜は成形ツールを超えて広げられている。膜はシリコーンゴムのようなエラストマー材から作られている。広げられた膜は、積層体を結合するように作用し、そして空気を取り除く。
雄型の上に、雄型の頂部の上に位置する第1の部位及び雄型の片側に突き出す第2の部位を有する被成形材と隔壁とを載置する工程と、
隔壁の全域に亘って圧力差を与え、圧力差を与える際に雄型を超えて隔壁を広げることにより、雄型の側部に被成形材の第2の部位を接触させて次第に変形させる工程と、を含み、
前記隔壁は、該隔壁の平面内で5MPa超の引張係数を有することを特徴とする方法を提供する。
雄型の上に、雄型の頂部の上に位置する第1の部位及び雄型の片側に突き出す第2の部位を有する被成形材と、支持膜と、隔壁とを載置する工程であって、支持膜と隔壁は、被成形材の対向する側部に配置される工程と、
被成形材の第2の部位の重さを支持膜で支持する工程と、
隔壁の全域に亘って圧力差を与え、圧力差を与える際に雄型を超えて隔壁を広げることにより、雄型の側部に支持膜と被成形材の第2の部位を接触させて次第に変形させる工程と、を含み、
隔壁は、隔壁の平面内で、支持膜の平面内での剛性よりも大きい剛性を有することを特徴とする方法を提供する。
k=P/δ
によって定義される剛性kである。
ここでδは、引張力Pが与えられている状態でのたわみ距離である。
図1は、飛行機の断面C字状のスパーを形成するのに使用される、雄型の成形減容化ツール2と、一対のエッジバー3である。図2は、図1の線A−Aに沿う断面図である。図2に示すように、ツール2とエッジバー3はテーブル1に取り付けられている。
