Abstract:

Glass fiber reinforced resin is the most widely used engineering composite material. Since the end of the 20th century, more and more attention has been paid to the interface bonding between glass fiber and resin matrix. The nanocomposite coating called "sizing" on the surface of glass fiber contributes greatly to the smooth production and application of glass fiber. In addition, sizing serves as a crucial "chemical bridge" for the interface bonding or interaction between glass fiber and the resin matrix. However, the sizing formulations of giant glass fiber manufacturers are highly confidential, and the related industries also lack comprehensive or reliable database on the science and technology of glass fiber sizing, limiting the acquisition the sizing knowledge and effect in composite products for researchers. In this work, the characterization and analysis methods of glass fiber sizing agents were reviewed through extensive comparative analysis of published works, so as to help the R&D and production personnel in composite industry to better understand the role of glass fiber sizing in reinforced composites. In this work, the basic knowledge of glass fiber sizing was introduced first in brief. Then, some typical characterization and analytical methods of sizing were introduced. Finally, the current research status was summarized and the challenges of characterization technology were discussed and prospected.

Key words: glass fiber, sizing, interface phase, surface properties, composite materials

摘要：

玻璃纤维增强树脂材料是应用最为广泛的工程复合材料。自20世纪末以来，玻璃纤维与基体树脂之间的界面结合越来越被关注，浸润剂是玻璃纤维表面处理的功能性复合涂层，是玻璃纤维生产与使用顺畅性的重要保障，也是构建玻璃纤维与树脂界面结合的重要“化学桥梁”。然而浸润剂配方具有高度保密性，行业内也缺乏系统可靠的浸润剂技术数据库，限制了人们对浸润剂知识及其作用的理解。通过对已经公开发表的相关文献进行广泛对比分析，本文对玻璃纤维浸润剂目前的表征与分析方法进行综述。首先对浸润剂的基础知识进行了简单概括，随后介绍了浸润剂的典型表征与分析技术，最后对浸润剂表征技术的发展现状、行业难点进行总结与展望，从而帮助复合材料行业的研发与生产人员更好地理解玻璃纤维浸润剂在增强复合材料中的作用。
