Abstract

This paper investigates the effect of fiber surface treatment on various properties of hair fiber reinforced composites. Human hair fiber reinforced modified epoxidized soybean oil based composites were prepared by compression molding technique. Acid treatment of hair fibers was carried out by using three different concentrations of HCl solution (0.25%, 0.75%, and 1%, respectively) in order to achieve improvement in adhesion between the fiber and the matrix. Epoxidized soybean oil was modified using methacrylic acid and methacrylic anhydride to form methacrylic anhydride modified epoxidized soybean oil. Rosin acid derivative (a rigid comonomer) was prepared and used as a crosslinker. Fourier‐transform infrared spectroscopy was carried out to study the interaction among the components of the composites. Various properties, namely, mechanical, thermal, flame resistance, and chemical resistance were checked. Scanning electron microscopy of the fractured surface of the composites was carried out to examine the morphologies. Hair fibers treated with 0.75% of HCl showed maximum improvement in all the properties and could be employed as reinforcement in various composites to be used for structural applications.

人发纤维增强改性环氧化大豆油基复合材料的理化性能研究

本文研究了纤维表面处理对头发纤维增强复合材料各种性能的影响。采用压缩成型技术制备了人发纤维增强改性环氧化大豆油基复合材料。使用三种不同浓度的盐酸溶液（分别为 0.25%、0.75% 和 1%）对头发纤维进行酸处理，以提高纤维与基体之间的粘附性。使用甲基丙烯酸和甲基丙烯酸酐对环氧化大豆油进行改性，形成甲基丙烯酸酐改性环氧化大豆油。制备了松香酸衍生物（一种刚性共聚单体），并将其用作交联剂。傅立叶变换红外光谱法用于研究复合材料各组分之间的相互作用。对各种性能，即机械性能、热性能、阻燃性能和耐化学性能进行了检测。对复合材料的断裂表面进行了扫描电子显微镜观察，以检查其形态。用 0.75% 的盐酸处理过的毛发纤维在所有性能方面都得到了最大程度的改善，可在各种复合材料中用作结构应用的增强材料。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
