Summary

The dynamic shear modulus of Textron Specialty Materials' SCS-6 SiC fiber was measured in the temperature range 296-873 K using an inverted torsion pendulum. The moment of inertia of the torsion pendulum was determined using a standard pure iron specimen of known shear modulus. The dynamic shear moduli of the chemically vapor deposited fiber was calculated from the measured oscillation frequencies. The ambient dynamic shear modulus of the SCS-6 SiC fiber and its temperature dependence were determined to be 150 GPa and -0.01 GPa/K, respectively.
