Abstract

Abstract: To evaluate the durability of high-performance fibers in extreme environments, this study compared the aging resistance behaviors of heteroaromatic polyamide fiber (aramid Ⅲ) and poly-p-phenylene benzobisoxazole (PBO) fiber in 30% (mass fraction) sulfuric acid (H₂SO₄) and sodium hydroxide (NaOH) solutions. Experiments were conducted under two temperature conditions (25 ℃ and 80 ℃) to systematically analyze the performance degradation laws and intrinsic mechanisms of PBO fiber in acidic and alkaline environments. The results show that PBO fiber exhibits superior acid and alkali resistance compared to aramid Ⅲ fiber. Elevated temperature significantly accelerates the aging rate, with the degree of performance degradation at 80 ℃ being much greater than that at 25 ℃. The corrosive effect of the acidic environment (H₂SO₄) on PBO fiber is more severe than that of the alkaline environment (NaOH). The amide bonds in aramid Ⅲ fiber are prone to hydrolysis, while the benzoxazole ring structure of PBO fiber endows it with higher chemical stability. The research findings provide important references for fiber material selection in applications such as chemical protection and high-temperature filtration.

Key words: aramid Ⅲ fiber, poly-p-phenylene benzobisoxazole (PBO) fiber, acid and alkali aging, mechanical properties, chemical structure
