It was found that the aging behaves of PBO fiber was susceptible to UV light. The cortex of the fiber was damaged severely during the 192 h accelerated UV light aging period, which led to significant reduction of tensile strength of fiber. The moisture had an evidently negative effect on the aging behaves of PBO fiber whether aging with UV light or not, and the effect was more obvious when exposed to UV light. The possible mechanism was the penetration of water molecules into the fiber‘s interior, which led to the formation of microfibril and the decline of fiber tensile strength. Increasing aging temperature can promote the penetration ability of water molecules, which speeded the decline of fiber tensile strength. The fibers aging in high humidity environments at a fixed temperature  degraded more quickly. PBO fiber had excellent stability in isolation from moisture and ultraviolet radiation. 收稿日期: 2010-05-26      ZTFLH:  TQ342   基金资助: 国家自然科学基金50703010和50973028资助项目。 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 宋波 傅倩 刘小云 庄启昕 韩哲文 44.8K 链接本文: https://www.cjmr.org/CN/      或      https://www.cjmr.org/CN/Y2010/V24/I5/487 [1]R.J.
