Abstract
This paper focuses on the modification technologies of Poly (p-phenylene benzobisoxazole) (PBO) fibers and their research progress. It is found that the modification of compression resistance, surface inertia, and ultraviolet (UV) aging resistance of PBO fibers can greatly promote the wide application of PBO fibers in advanced composites. More researches are yet to be done on the new modification technologies of PBO fibers in compression resistance, and the future development direction of surface modification and UV aging resistance modification is towards realizing non-destructive modification and large-scale and industrialized online treatment.
