Abstract
Official abstract text for this publication.
Disclosed herein is a production method of a shroud segment that includes a forming process of molding a cylindrical fiber fabric ( 10 ) into a shroud segment shape by pressing a cylindrical surface of the fiber fabric, and a matrix forming process of impregnating the fiber fabric molded into the shroud segment shape with a matrix.
First claim
Opening claim text (preview).
The invention claimed is: 1. A production method of a shroud segment made of a fiber-reinforced composite material which is arranged between a casing enclosing a rotor blade and the rotor blade in a gas turbine engine, the shroud segment including a facing portion and a hook portion, the facing portion facing a rotational region of the rotor blade, the hook portion standing on the facing portion and being locked with the casing, the production method of a shroud segment comprising: a forming process of molding a cylindrical fiber fabric into a shroud segment shape by pressing a cylindrical surface of the fiber fabric; and a matrix forming process of impregnating the fiber fabric molded into the shroud segment shape with a matrix, wherein when the cylindrical surface of the fiber fabric is pressed at the forming process, a gap used to allow excessive deformation of the fiber fabric is provided so as to face an end of the facing portion other than the hook portion. 2. A production method of a shroud segment made of a fiber-reinforced composite material which is arranged between a casing enclosing a rotor blade and the rotor blade in a gas turbine engine, the production method of a shroud segment comprising: a forming process of molding a cylindrical fiber fabric into a shroud segment shape by pressing a cylindrical surface of the fiber fabric; and a matrix forming process of impregnating the fiber fabric molded into the shroud segment shape with a matrix, wherein a reinforcement member is arranged and accommodated in the cylindrical fiber fabric and the fiber fabric is molded, together with the reinforcement member, at the forming process. 3. A shroud segment arranged between a casing enclosing a rotor blade and the rotor blade in a gas turbine engine, the shroud segment comprising: a) a fiber-reinforced composite material molded into a shape to engage with said casing, comprising: a plurality of continuous fibers which continue without being cut in an extending direction thereof; and a matrix which is molded by adhesion to the continuous fibers b) wherein said shroud segment further comprises a reinforcement member molded inside the plurality of continuous fibers.
