The results showed that the wettability of epoxy to the silica sol modified carbon fiber has been improved greatly due to the introduction of polar functional groups such as Si—O—Si and —NH2. The coating of silica sol improved the adhesion between carbon fiber and epoxy, resulting in an increasement of 62.74% of the lateral tensile strength, comparing with that of the unmodified carbon fiber reinforced composites, but little change of the longitudinal tensile strength. Likewise, the lateral tensile strength of composites from carbon fiber pretreated by nitric acid and subsequently modified by silica sol was increased by 35.27%, comparing with composites from pure nitric acid treated carbon fiber.      ZTFLH:  TQ327.3   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 杨洪斌 王靖 吴惠敏 傅雅琴 44.8K 链接本文: https://www.cjmr.org/CN/      或      https://www.cjmr.org/CN/Y2013/V27/I1/108 1 Bing Xu, Xiaoshu Wang, Yun Lu, Surface modification of polyacrylonitrile-based carbon fiber and its interaction with imide, Applied Surface Science, 253(5), 2695(2006) 2 Zhi Xu, Li Chen, Yudong Huang, Jialu Li, Xiaoqing Wu, Xueming Li, Yanan Jiao, Wettability of carbon fibers modified by acrylic acid and interface properties of carbon fiber/epoxy, European Polymer Journal, 44(2), 494(2008) 3 H.
