AbstractIn situ studies of structure and performance changes in aromatic copolysulfonamide (co-PSA) fibers during stretching at different thermal exposure temperature range from room temperature to 300 degrees C were carried out using synchrotron small angle X-ray scattering and wide angle X-ray scattering techniques. Results showed that the optimum microstructure and mechanical property of co-PSA fibers were achieved when stretched at 200 degrees C, the fibril length, fibril misorientation, crystal sizes L-002 reached minimum, the long period became maximum at the same strain indicating that lamella and fibrils aligned perfectly, fiber structure compactness at 200 degrees C. During stretching at RT to 200 degrees C, at low strain, fibril length, crystal size L-002 increased, fibrils oriented along stretching direction, the long period was enlarged; the opposite trend evolution of structure appeared under high strain. But stretching at 300 degrees C, L-002 increased, fibril orientation became poor, the lamellae destroyed easily resulting in the decreasing strength. It can be concluded that co-PSA fibers remain good property under thermal at 200 degrees C, external force use environment.
