Description
紙を以下の組成で製造した:パラ系アラミドフィブリド50重量%、パラ系アラミドパルプ20重量%、および繊維長6mm、線密度1.7デシテックスのパラ系アラミドショートカット30重量%。いずれの紙も、坪量は55~56g/m2であった。
例1の紙のストリップに、ピペットを用いて液体樹脂の液滴を供給した。紙のストリップ1枚当たり5滴の樹脂を施与した。樹脂は、イソプロパノールに溶解させたフェノールレゾール樹脂(Bakelite(登録商標)PF1143V)であり、室温で使用した。紙を24時間放置し、紙の裏側に認められた樹脂の量を測定することによって、樹脂の浸透を調べた。結果の写真を図2に示す。結果を表2にまとめる。
紙の組成の影響を調べるために、表3に示す組成の紙を製造した。
例3に記載の紙の透気度を、ISO 5636/3に準拠して、透気度測定装置L&W166(Lorentzen & Wettre)を用いて測定した。得られた値がガーレーである。これは、ある圧力で、ある体積の空気が紙を通過するのに要する時間(秒)である。ガーレーが低いほど、紙の透気度は高い。結果を表4に示す。
