摘要

摘要:本文研究了以二硼化钛(TiB2)为填料制备四角星纤维(CQF)增强环氧复合材料。采用压缩成型技术制备复合材料样品。CQF的体积保持在30 wt%， TiB2以0 % ~ 10 %的重量比例加入。对复合材料的力学、热、粘弹性和介电性能进行了评价。采用扫描电镜(SEM)研究了填料添加量对拉伸断裂试样基体-纤维结合的影响。结果表明，添加8 wt%填料的复合材料具有较高的力学性能和相当的介电性能。基于这些发现，复合材料被推荐用于汽车、电气和建筑行业。

Mechanical and dielectric properties of Cissus Quadrangularis fiber-reinforced epoxy/TiB2 hybrid composites

Abstract This study focus on fabricating a Cissus Quadrangularis Fiber (CQF) reinforced epoxy hybrid composite with the addition of titanium diboride (TiB2) as filler. A compression molding technique was employed to fabricate the composite samples. The volume of the CQF was maintained at 30 wt%, and TiB2 was added with various weight proportions ranging from 0 % to 10 %. The mechanical, thermal, viscoelastic, and dielectric properties of the hybrid composite samples were evaluated. Scanning electron microscopy (SEM) was used to examine the impact of filler addition on the matrix-fiber bonding of the tensile fractured test specimens. The results revealed that the composite with 8 wt% filler produced high mechanical properties and comparable dielectric properties. Based on these findings, the fabricated composites are recommended for suitable applications in the automotive, electrical, and construction industries.

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.
