In this work, polyacrylonitrile hollow fiber was oxidized, carbonized, and activated by carbon dioxide into activated hollow carbon fiber. The effects of the activation temperature on the characteristics of the resulting activated hollow carbon fiber, including the mechanical properties, the surface

✦ 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.
