Heat treated poly(p-phenylene benzobisthiazole) (PBZT) fibers tested in tension result in two types of failure modes. In failure mode I, the fiber exhibits a relatively sharp break; mode I1 is characterized by significant axial fiber splitting. Approximately 20% of the fibers failed in mode I1 when
## Abstract Fibers spun from anisotropic solutions of a lyotropic rigidβrod polymer, poly(paraβphenylene benzobisthiazole) [PBZT], were coagulated into homogeneous nonsolvents including a solution of 18% iodine/82% ethanol, ethanol, and water. The effect of these coagulants on the structure and mec
