摘要：
The influence of heat-treatment in nitrogen atmosphere at different temperatures, time and stress on the physical-chemical properties and the surface of PBO fibers were investigated through Single fiber tensile, TG and SEM analysis. The results show that the tensile strength of PBO fibers dose not change so much before 600 degrees C, but for heat-treatment at 650 degrees C, there is a significant decrease in strength. Heat-treatment also makes the surface of fibers rougher than untreated fibers.
