実施例1において、コークスの代わりにガラス繊維(繊維径10μm、繊維長30μm)が同量(30体積%)用いられたところ、固着応力は0.40MPa(判定:×)であった。
比較例5において、ポリテトラフルオロエチレン樹脂量が90体積%に、またガラス繊維量が10体積%に変更されて用いられたところ、固着応力は0.72MPa(判定:×)であった。
実施例1において、コークスとして平均粒径が35μmのものが同量(30体積%)用いられたところ、固着応力は0.28MPa(判定:×)であった。
比較例7において、ポリテトラフルオロエチレン樹脂量が90体積%に、またコークス量が10体積%に変更されて用いられたところ、固着応力は0.74MPa(判定:×)であった。
実施例1において、コークスのかわりに平均粒径30μmの球状ブロンズが同量(30体積%)用いられたところ、固着応力は0.33MPa(判定:×)であった。
