第1の工程は、高温(130℃)で混合する。液状エポキシ樹脂、熱可塑性樹脂、強化剤。実施例1では、Flacktek、Inc.、Landrum、South Carolinaから得た、混合カップ用であるタイプ「MAX100」中で、49.0グラムのEpon 828、23.6グラムのPKHP−200、及び12.5グラムのP2650Aを混合した。このカップをオーブン中で120℃に加熱し、次に、Hauschild Engineering & Co.、KG、Hamm、ドイツから得た、モデル「DAC150 FVZ SPEEDMIXER」を使用して2分間、3,000rpmで均一に分散させた。次に、この混合物を130℃のオーブンに移し、1時間保持し、この後、これをミキサーに戻して、Z−6040を2.0グラム加え、均一になるまで、3,000rpmで2分間、混合した。
実施例1に一般に記載されている手順を繰り返し、この場合、組成物は、表1に一覧表示されている重量百分率に従って修正した。
上記の実施例は、以下の通り、販売名「SCOTCH−WELD STRUCTURAL CORE SPLICE ADHESIVE FILM AF−3024」で、3M Companyから得た、比較例材料に対して評価した。結果が表2に一覧表示されている。このフィルムは、固体エポキシ及び液体エポキシ、エポキシ硬化剤、ニトリルゴム、化学発泡剤(連続気泡構造をもたらす)を含んでおり、熱可塑性樹脂は含んでいない。
サンプルは、AECMA(欧州航空機及び部品製造業者協会(Associationof European Aircraft and Component Manufacturers))規格EN2667−2に従い、管せん断強度について測定した。硬化周期加熱速度は、70°F(21.1℃)から250°F(121.1℃)まで3℃/分とし、温度を250°F(121.1℃)で90分間保持した。結果は、MPaで報告されている。
サンプルは、AECMA規格EN2667−3に従い、膨張範囲について測定した。この硬化温度は、5°F/分(2.8℃/分間)の速度で、60分間、250°F(121.1℃)とした。結果は、元の厚さに対する変化百分率として報告する。
8×8インチ×20ミル(20.32×20.32cm×0.51mm)の2024アルミニウムパネルを、パネルの端から端まで6インチ(15.24cm)のところに刻み目を入れた。このパネルをイソプロピルアルコールで清浄して乾燥し、1×2インチ(2.54×5.08cm)の試験サンプルを、2インチ(5.08cm)の長さの方向に上記の刻線に沿って並べ、パネルにラミネートした。次に、このパネルをオーブン中に垂直に置き、5°F/分(2.8℃/分)の速度で、250°F(121.1℃)まで昇温して、60分間保持し、次に、オーブンから取り出した。上記のサンプルを70°F(21.1℃)まで冷却した後、材料が刻線を超えて流れた距離を測定した。
サンプルは0°F(−17.8℃)での保管から取り出し、70°F(21.1℃)に保持し、膨張率試験を定期的に行った。膨張率の顕著な変化が明白になる前の時間の長さを記録した。
防火性要件を満足するよう配合された、実施例5は、米国連邦航空規定(FAR)の試験法25.856に合格した。
