Abstract: A steam cooled type gas turbine has a steam chamber unit formed in one unit having a compact structure through which steam, as a cooling medium, is appropriately supplied, used for cooling and recovered. The steam chamber unit (1) formed in one unit has a steam supply passage (31) for leading cooling steam, a steam connection passage (32) for leading the cooling steam which has cooled a front stage (5) to a subsequent stage (6) and a steam recovery passage (33) for recovering the cooling steam which has cooled a plurality of the stages. The unit further has a heat insulating structural member (8) for insulation of heat from a moving blade (9) and a stationary blade supporting portion (7), both provided in an inner circumferential surface portion of the steam chamber unit.

Abstract: A carbon fiber composition containing carbon fiber, at least one vinyl addition polymer having at least one oxirane ring and, occasionally, one or more polyfunctional epoxy compounds is provided. This carbon fiber composition facilitates the handling of carbon fibers and improves the physical properties of carbon fiber composite materials.
