Description
一実施形態に従って、上記に開示される硬化性プリプレグを作製するための方法は、織布に硬化性マトリックス樹脂を部分的に含浸させ、その後に表面開口部列を作るための熱処理が続くことを含む。織布にマトリックス樹脂を部分的に含浸させるための方法は、限
定されないが、「ホットメルト」プリプレグ化法が好適である。一般に、このプリプレグ化法は、部分的に含浸したプリプレグを産出するため、布層にホットメルト樹脂組成物を、溶解形態で、含浸させることを特徴とする。含浸は、布層を2つの樹脂フィルムの間に挟み、その得られた積層体を高温板、加熱ローラによって、またはその積層体を高温の金属ベルトの間で圧迫する方法によって、圧迫することによって、なされてもよい。あるいは、布は、1つの側面のみに樹脂フィルムが積層され、反対側は実質的に樹脂のない状態のままにされる。
れ、そこで多孔質プリプレグは冷却され、樹脂が固化する。冷却されたプリプレグは、次いで引きローラ89、90によって運ばれ、かつ付加的なガイドローラによって巻きロール91へと導かれ、そこで巻き上げられる。この種類の過程は、平織布、特に、布の厚さおよび含浸フィルム(複数可)に起因して熱処理が迅速である低GSM布、の使用を基にしたプリプレグ内に開口部を作るのに特に適している。
本明細書に記載される硬化性プリプレグを生成するためのマトリックス樹脂は、硬化性ホットメルト組成物に基づき、最初はほぼ室温(20℃〜25℃)で固体または半固体であり、材料に適用される高温で溶融され、冷却時に固まり、硬化によって硬化可能であることを特徴とする。さらに、マトリックス樹脂は、形成空気ポケット、およびそれに続く、熱処理による空気ポケットの上方の開口部の形成を可能にするために、十分な粘度および濡れ特性を有するべきである。一実施形態において、ホットメルト樹脂組成物は、主要成分として1つ以上の熱硬化性樹脂を含む硬化性熱硬化性樹脂組成物であり、いかなる有機溶剤、例えばアセトン、メチルエチルケトン(MEK)、ジオキソラン、アルコール、も実質的に含まない。最終硬化物を生成するために使用されるとき、これらの熱硬化性樹脂は、触媒あるいは硬化剤、熱、または2つの組み合わせの使用によって硬化される。
複合物部品を形成するため、本明細書に記載される複数の硬化性プリプレグは、プリプレグ積層に積層される場合があり、次いで、その積層は圧密され、硬化される。圧密および硬化は、単一の段階として実施されてもよく、別々に実施されてもよい。
実施例
プリプレグ布は、強化エポキシ系樹脂、Cycom5320(Cytec Industries Inc.から入手可能)から形成される2つの樹脂フィルムを、8枚繻子織、炭素繊維布の上面および底面に押し付け、それによって、布を2つの樹脂フィルムに挟む、プリプレグ化機械を使用したホットメルト過程によって調製した。それぞれの樹脂フィルムは、シリコーンコーティングされた剥離紙上に形成され、フィルムごとに106gsmの単位面積重量を有する。炭素−繊維布は、(370)gsmのFAWおよび0.0146インチの厚さを有する。熱および圧力を、積層体に加え、樹脂フィルムを溶かし、部分的に布の厚さを通って浸透させた。剥離紙の1枚を、ロールへの巻上げを容易にするためにプリプレグ化後に滑らかなポリエステルフィルムと置き換えた。上部に剥離紙、下にポリエステルフィルムを有する、事前含浸したプリプレグを、200°F(93℃)で2〜5分間オーブン内で加熱した。この加熱サイクル時間は、プリプレグの機械的または物理的特性に影響を与えずに包囲された空気ポケットを開放するのに十分であることが分かっている。図15〜17は、それぞれ1分、4分、7.5分の加熱時間の、剥離紙を取り除いたプリプレグ表面の上面画像を示す。開口部は、繻子織布内の上下交差位置(すなわち、上方/下方トウ部分)と重なり合った。図15〜17から分かるように、開口部のサイズは経時的に大きくなった。7.5分後、同じ列および隣接するトウの上下交差位置に隣接する行に並んだ一部の開口部は、図13の画像から分かるように、お互いに接触していた。これらの開口部は、繻子織布内の上方/下方トウ部分に対応する(図7の参照番号70に示されるように)。開口部は、熱処理されたプリプレグの剥離紙側にのみ形成されたことが留意された。
プリプレグ布を、図12に表されるプリプレグ化システムを使用することによって作成した。使用された布は、平織炭素繊維布で、布の相反する面に適用された樹脂フィルムを、Cycom5320エポキシ系樹脂から形成した。それぞれの樹脂フィルムは、シリコーンコーティングされた剥離紙上に形成され、55gsmの単位面積重量を有した。炭素
繊維布は、190gsmのFAWおよび0.0083インチの厚さを有する。部分含浸については、20psiを第1のニップで適用し、加熱プレートでの温度は220°F(104℃)であり、圧縮力を制限するために0.5インチ(12.7mm)未満のギャップを第2のニップで提供した。図18は、剥離紙が取り除かれた、熱処理されたプリプレグ表面の上面画像を示す。プリプレグ表面内の開口部は、平織布内の隙間と一致する。さらに、開口部は熱処理されたプリプレグの双方の主要表面に形成されることが留意された。
比較のために、図1で説明されるように、表面開口部を作成するための熱後処理を用いずに、対照プリプレグを調製した。図19は、結果として生じる、連続的な樹脂フィルムの下に形成される、閉じ込められた気泡のあるプリプレグ表面を示す。これらの気泡は、繻子織布内の上方/下方トウ部分に対応する。このため、硬化前の熱処理がない場合、空気ポケットから閉じ込められた空気、および逃げることのできない積み重なりの間にある空気が、連続的な樹脂フィルムがプリプレグからの空気の除去を制限することに起因して、結果として生じる硬化したプリプレグ内に留まることが見られた。
実施例1に記載されるように、5320/8HSプリプレグ材料の15の層から成る12インチ×12インチのモノリシックパネルを構築し、硬化した。比較のために、未処理5320/8HSプリプレグ材料を使用して同じパネルを構築し、同じ条件下で硬化した。結果として生じる空隙率は、処理なしの1.31%から熱処理ありで0.04%まで減少した。図20は、熱処理なしの材料から成るパネルの断面を示し、図21は、熱処理された材料から成るパネルの断面を示す。
ハニカムコアサンドイッチ構造を図13に示される構成に基づいて組み立て、10の多孔質プリプレグ層(201)がハニカムコア(202)の上に置かれ、14の多孔質プリプレグ層(203)がハニカムコアの下に置かれた。多孔質プリプレグ層を、繻子織炭素繊維布をCycom5320樹脂で部分的に含浸し、その後実施例1に記載されるように、表面開口部を作るために熱処理することによって生成した。組み立てられたサンドイッチ構造体を、真空バッグに入れ、室温で圧密し、オーブン内で(オートクレーブではない)で硬化した。
ハニカムコアサンドイッチ構造を、多孔質プリプレグ層を使用して組み立てた。これは、図13の構成を基にした。この構造体に使用される多孔質プリプレグ層は、平織炭素繊維布およびCycom5320樹脂から成り、プリプレグ層内の開口部は、実施例2に記載されるようにプリプレグ化過程中にその状態での加熱によって生成された。その後、組み立てられたサンドイッチ構造体を、真空バッグに入れ、室温で圧密し、オーブン内で(オートクレーブではない)硬化した。比較のために、プリプレグ層が表面開口部作るための熱処理がされなかった以外は同じ様式で、標準ハニカムコアサンドイッチ構造を組み立て、圧密し、硬化した。
硬化前の真空下にある時間数、あるいはかさ減らしサイクルと称される時間数を減少し、それによって全体の硬化時間が少なくすることができるかどうかを判定するために、複合物パネルを5320−1/8HSプリプレグから製造した。硬化前の真空下にある時間は、熱処理プリプレグおよび未処理プリプレグ(対照として)を使用して、0.5時間〜16時間の範囲に及んだ。
硬化前の真空下にあるかさを減らす時間数を減少し、それによって全体の硬化時間が少なくすることができるどうかを判定するために、複合物パネルを5320−1/PWプリプレグから製造した。硬化前の真空下にある時間は、熱処理プリプレグおよび未処理プリプレグ(対照として)の双方を使用して、0.5時間〜16時間の範囲に及んだ。
