✦ Synopsis

Abstracts torsion testing under cyclic loading to lo6 cycles. It was learned that carbon-carbon creeps or takes on a permanent deformation, but is resistant to fatigue loading and in general can retain its stiffness and strength up to lo6 cycles. Fiber bundle slipping and re-sticking is believed to be the mechanism by which creep takes place and the higher the composite density the less pronounced the effect.
