DIN54310、
測定温度:23℃。
試験を行う熱可塑性樹脂の平らなフィルム(単位面積当りのコーティング重量:200g/m2)をポリエステル-羊毛の織物(55/45重量%、褐色、単位面積当りのコーティング重量:210g/m2、製造者:Becker Tuche(ドイツ)またはMarzotto(イタリア))の上に二重ベルトプレスを用いて層状に貼り合わせる。このときの積層温度は熱可塑性樹脂の融点よりも30℃高い。貼り合せシートを50℃において24時間貯蔵した後、24×8cmのサンプルを切り出す。プラスチックのフレーム(15×5cm)をサンプルの上に置き、その下の細い側部にワックスを塗布した紙片を配置する。新たに用意した脱泡したエポキシドの混合物を、フレームに3mmの高さまで充填する。エポキシドを23℃において12〜16時間にわたって硬化させる。次いで、フレームを除去する。ワックスを塗布した紙片によって、熱可塑性樹脂のフィルムとエポキシドが約3cmの長さにわたって分離される。
ASTM D2344M、
測定温度:23℃および80℃。
最初に、330×330×4mmの寸法を有するプレートを樹脂トランスファー成形(RTM)によって製造する。これを行うために、単位面積当りのコーティング重量が298g/m2の一方向炭素繊維のフィラメントを、80℃に予熱した加熱可能なプレスの金型キャビティの中に手で配置し、その上に、18gの熱可塑性樹脂の粉末を篩を用いて均一に分散させ、この操作を15回繰り返し、このとき、一方向炭素繊維のフィラメントの1番目の層に対して2番目の層を−45°ずらし、3番目の層を+45°ずらし、そして4番目の層を90°ずらす。このようにすると、16層の構造の5番目の層は1番目の層と同じ方向を有する。各々の層の上に18gの熱可塑性樹脂の粉末を散布するが、16番目の層の上には散布しない。金型を閉鎖した後、120℃までの加熱を真空(残留圧力:0.05mbar)の下で行い、この温度に達したときに、80℃に予熱した単一成分エポキシ樹脂(HexFlow RTM6(Hexcel Corporation、米国))を注入する。硬化を180℃、6barの圧力において90分間行う。次いで、圧力を低下させ、同時に冷却を行う。金型を開放するまで真空を維持する。一方向炭素繊維のフィラメントとしてIMS60 E13(東邦テナックス(株)、日本)を用いる。プレートの品質の検査を超音波を用いて行った後、試験片を24×8×4mmの寸法で切り出す。測定を行う前に、試験片を60分で測定温度にする。圧力試験は気候室の中で行う。
AITM 1.0010(エアバス基準)、
測定温度:23℃。
プレートの製造は、ILSS試験について説明した通りである。品質の検査を超音波を用いて行った後、試験片を150×100×4mmの寸法で切り出す。
