Description
摩擦材料に対する出発材料は、図1及び図2に基づくあや織り2/2の斜めに延びる流路状のくぼみを有する織物を形成した。この織物は、レゾール系の液状樹脂を、全質量の50%の樹脂含有量になるように含浸された。このようにして作られたプリプレグの硬化プロセスは、約80℃の温度で約50分にわたる処理で始められた。図4による機械的な加圧プロセスの枠組みにおける加圧力の印加は2段階で行われ、その第1の約10分の加圧段階は硬化プロセスの開始後約50分で始められ、約4×105Paの加圧力のもとに行われ、一方続く第2の加圧段階に対しては加圧力は約7×105Paに高められ、その第2の加圧段階は約65分継続した。特に第1の加圧段階の開始と同時に、硬化温度は、第2の加圧段階が始まるちょっと前に約130℃に達するように高められた。第2の加圧段階の経過においてさらに硬化温度はもう一度高められ、好ましくは約150℃に高められた。硬化温度を周囲温度に下げることによって、第2の加圧段階も加圧力を周囲圧に下げることによりほぼ同時に終了した。硬化温度を高め始めてからその周囲温度へ下げるまでの全硬化時間は約125分であった。
上述の好ましい方法に従い作られた6つの試料と同じ50重量%の樹脂含有量を有するが加圧されない1つの試料との間の材料特性の相違を確認するため、これらの試料が圧縮試験及び試験規格ASTM F 36-66によるスプリングバック試験にかけられた。この規格に従えば、厚さaの各試料が先ず無負荷状態で測定され、22.2N(5lbf)で15秒の負荷後測定され厚さpが生じ、1112N(250lbf)で60秒の負荷後測定され厚さmが生じ、さらに22.2N(5lbf)で15秒の負荷後測定され厚さrが生じる(表2参照)。
