On the test of carbon carbon composite turbine blade
- Institute of Space and Astronautical Science, Kanagawa (Japan)
The research on C/C composites has reached the step of practical application of engineering materials in many countries in the world. C/C composites show high specific strength in comparison with other materials. It is important as structural materials for space vehicles and air craft. C/C composites have good thermal expansion, excellent heat impact resistance and high temperature strength, except that it has oxidation resistance. The authors have done research and development on an air turbo ramjet engine which is intended for space vehicles (ultra-high speed air craft). Carbon fiber reinforced yarn has been examined under the actual loading and rotor. The objective of this experiment is to obtain information on the environmental resistance (above 30.000 rpm, test atmosphere 70% H{sub 2}, 30% H{sub 2}O) of a ACC turbine blade. There is a difference in the fabrication method, as well as the fiber orientation and weaving method. Test results show that the fracture behavior of C/C composite turbine blade is strongly dependent on the weaving orientation of carbon fibers.
