Morphology and tensile behavior of wet‐spun fibers of poly‐ p ‐phenylene benzobisthiazole have been investigated. The as‐spun fibers contain a large number of voids, which result in void‐localized tensile failure. The stress–strain behavior is elastic–plastic with strain hardening. This behavior is shown to be the result of residual stresses which arise during the wet‐spinning process.
