である。The most widely used materials for friction elements, such as those used in water turbines, are bronze and wood laminates.
水力タービン摩擦素子にかかる荷重の増加に伴い，上記
材料は現在の一層厳重な信頼性要求を満たせなくなり、
更に重要なことは，上記材料が無潤滑条件にまったく不
適当なことである。As the loads on water turbine friction elements increase, the above materials no longer meet today's more stringent reliability requirements.
More importantly, these materials are completely unsuitable for non-lubricated conditions.
また当業界では、ポリアミド、フェノールーホルムアル
デヒド，その他の合成樹脂に基づく重合材料を使用する
