Although high performance fibers possess higher thermal resistant properties, they show very low sunlight stability. In this paper, a new sol-gel treatment method was used to enhance their light-resistant properties. Their mechanical property retention ratios (tenacity, extension, modulus) of fibers treated with titanium hydrosol were higher than those of the original Kevlar®129, PBO, and Kermel® fibers after light irradiation. Moreover, Kermel® fiber showed the highest improvement among the three kinds of fibers. |
