Abstract
A dense silicon carbide matrix composite reinforced by Hi-Nicalon fibers coated with boron nitride was fabricated by slurry impregnation and subsequent reaction sintering with molten silicon. The effect of the fiber coating structure and the infiltrating metal composition on the mechanical properties of the composite was investigated. The fabrication process for the combustor liner and the shroud segment for a 15 MW gas turbine was developed. The small combustor liner and the shroud segment with some machined notches were evaluated in a combustion test at 1773 K and atmospheric pressure. Excellent durability for gas turbine hot parts was recognized.
