Description
約6インチ×6インチ×0.08インチに測って切った、予備含浸済みMI−CMCの2つのパネルを試験した。パネルの材料は、HiPerComp(商標)の商標名で入手可能である。パネルを、約6インチの長さ×0.5インチの幅のMI−CMC試験棒にカットした。製造されたままのHiPerComp(商標)CMCは、材料の比例限界ストレスの測定に影響を及ぼす、マトリックス部分における残留ストレスを含むことが知られている。そのような残留ストレスを和らげるために、6つの試験棒を、(a)約2400°F(約1315℃)の空気中で約100時間加熱することによって、(b)真空下で約20分間、ケイ素の融点よりも高く再加熱することによって、又は双方の処理(a)及び(b)を用いることによって、アニールした。その後、熱処理したMI−CMC試験棒を、引張り試験を介して(ASTM C1275において概説される手順を用いて)、室温で破壊試験してして、熱処理した各MI−CMC試験棒のPL、E、及び極限強さを判定した。PLは、0.005%の歪みオフセット法を用いて判定した。試験した熱処理したMI−CMC試験棒は全て、HiPerComp(商標)の正常変動の範囲内の名目上等しい引張り強度特性(PL、E、及び極限強さ)を有した。
被覆Hi−Nicalon繊維で強化した予備含浸済みMI−CMC材料のパネルを、米国特許出願公開第2007/0099527号明細書及び米国特許第6024898号明細書に記載される手順に従って製造した。このパネルから試験MI−CMC試験棒を切り取って、実施例1に記載したものと同じ試験手順にかけた。実施例1に関して上述のように、アニール済み状態の3つのMI−CMC試験棒を引張り強度試験し、クラックあり状態の1つのMI−CMC試験棒を引張り強度試験し、補修済み状態の2つのMI−CMC試験棒を引張り強度試験した。アニール済み、クラックあり、及び補修済みのMI−CMC試験棒の引張り強度試験の結果を、以下の表2に示す。
