TURBINE ROTOR BLADE
PROBLEM TO BE SOLVED: To provide a turbine rotor blade at least partially formed of a ceramics-based composite material resisting a strong centrifugal force and difficult to rupture.SOLUTION: A turbine rotor blade comprises: a blade portion; and a tip shroud portion provided on an outer end of the blade portion, the blade portion and the tip shroud portion being formed of a ceramics-based composite material, at least part of the blade portion and at least part of the tip shroud portion being formed of one ceramics fiber fabric and connected to each other, a part of the ceramics fiber fabric constituting the blade portion and a part thereof constituting the tip shroud portion being bent to form a desired angle, assembled into a die, and formed integrally, and a ceramics matrix being formed in an obtained compact.SELECTED DRAWING: Figure 1
【課題】強い遠心力に耐え破壊し難い、少なくとも一部がセラミックス基複合部材からなるタービン動翼の提供。【解決手段】タービン動翼であって、翼部と、前記翼部の外端に備えられたチップシュラウド部とを有し、前記翼部と、前記チップシュラウド部とはセラミックス基複合部材からなり、前記翼部の少なくとも一部と、前記チップシュラウド部の少なくとも一部とが１つのセラミックス繊維織物から構成されていて繋がっており、前記セラミックス繊維織物における前記翼部を構成する部分と、前記チップシュラウド部を構成する部分とを所望の角度をなすように折り曲げ、型に組み付けて一体に成形し、得られた成形体にセラミックスマトリックスを形成した、タービン動翼。【選択図】図１
