COMPOSITE MATERIALS FOR TURBINE COMPRESSORS.
SOLAR TURBINES INTERNATIONAL SAN DIEGO CA
A program to investigate metal-matrix composite materials for possible application in aircraft compressor blades has been carried out. The program was divided into three phases. Phase I included a review of the turbojet engine compressor requirements and the definition of relevant guidelines that could be used to further define the mechanical property requirements of compressor components. Phase II was concerned with the development and validation of the selected screening tests. Phase III covered the detailed evaluation of the above mentioned composites, and again included material characterization and tensile testing plus ballistic impact, axial and flexural fatigue, creep rupture, and salt corrosion tests. In addition to Al-B and Al-SS, Ti-SiC was examined briefly as a possible candidate for operation in the temperature regimes up to 1000 F. Author
