Abstract
【解決手段】パイプ1は、筒状の強化繊維構造体22と、強化繊維構造体22の中心軸側である内側、および、外側を覆うことにより、当該中心軸を中心とする筒状のパイプ本体2を強化繊維構造体22と共に形成するマトリックス樹脂29とを備える。パイプ本体2の端部の外側面は、端面に向かうに従って直径が漸次減少する本体傾斜面を有する。パイプ本体2が他のパイプ本体と連結される際に、本体傾斜面が略筒状のカップリングと結合される。パイプ本体2では、強化繊維構造体22において本体傾斜面近傍に配置される部位が、中心軸に平行に伸びる複数の繊維束241にて構成される。これにより、強化繊維構造体22における繊維束が引っ張られてパイプ本体2から抜ける剪断破壊が本体傾斜面において生じることが防止され、本体傾斜面における剪断強度を向上することが実現される。
