図1および図2は、本発明の一実施態様に係る風車を示しており、とくに、翼本体部をFRPで構成した場合の例を示している。本発明に係る風車の翼に使用するFRPとしては、とくに限定されないが、強化繊維としては、例えば、炭素繊維、ガラス繊維等の無機繊維や、ケブラー繊維、ポリエチレン繊維、ポリアミド繊維などの有機繊維からなる強化繊維が挙げられる。翼の強度や剛性の制御の容易性の面からは、とくに炭素繊維が好ましい。FRPのマトリックス樹脂としては、たとえば、エポキシ樹脂、不飽和ポリエステル樹脂、ビニルエステル樹脂、フェノール樹脂等の熱硬化性樹脂が挙げられ、さらには、ポリアミド樹脂、ポリオレフィン樹脂、ジシクロペンタジエン樹脂、ポリウレタン樹脂等の熱可塑性樹脂も使用可能である。また、FRP製翼本体部の構造としては、その外殻構造のみ(表面材のみ)をFRP製として内部を中空にした構造、FRP製外郭の内部に軽量のコア材を介在または充填した、いわゆるサンドイッチ構造のいずれも採用可能である。コア材としては、弾性体や発泡材、ハニカム材の使用が可能であり、軽量化のためにはとくに発泡材が好ましい。発泡材の材質としては特に限定されず、たとえば、ポリウレタンやアクリル、ポリスチレン、ポリイミド、塩化ビニル、フェノールなどの高分子材料の低密度フォーム材などを使用できる。ハニカム材としては特に限定されず、たとえばアルミニウム合金、紙、アラミドペーパー等を使用することができる。
