Three different CVD SiC fibres were tested for bend stress relaxation (BSR) and tensile creep over a wide range of tempertures, times and stresses. Primary creep was always observed, even for creep strains on the order of 2%. The BSR and tensile creep results were compared using simple linear viscoelastic principles.
