Summary

Silicon carbide matrix composites reinforced with pitch based carbon fiber (Cf/SiC) were fabricated with an impregnation/high-pressure pyrolysis process. The matrix of silicon carbide was derived from polycarbosilane. The Cf/SiC composites were applied to a turbine rotor model. The specific strength of the Cf/SiC composites was higher than that of Si3N4 over 1000 °C. Foreign object damage (FOD) tests using ceramic particles were carried out in order to examine the impact fracture behavior of the Cf/SiC composites. At the impact velocity of over 600 m/sec, which corresponds to the maximum speed of the blade tips, the particles pierced through the Cf/SiC composites without catastrophic fracture. The residual strength was more than one-third of the initial strength. A cold spin test (CST) was carried out in order to study the fracture behavior by centrifugal force. Carbon/carbon (C/C) composites with different types of reinforcement were used as model materials. The fracture behavior of the felt C/C composites was quite similar to that of monolithic ceramics. In contrast, the fracture of the quasi-isotropic laminate C/C composites seemed to be controlled by the average tangential stress, as in the case of ductile materials.

Silicon carbide fiber reinforced silicon carbide composites (SiC/SiC) were fabricated with Hi-Nicalon and the improved polycarbosilane. The SiC/SiC composites were confirmed to have thermal and oxidation resistance by dynamic and static oxidation tests. Stationary parts, such as the combustion orifice liner model were fabricated and are carried out engine combustion environment test.
