Abstract

Abstract In this study, Indocalamus micro/nanofibers (IMFs) were extracted from natural Indocalamus leaves by physical processing and alkaline treatment. IMFs reinforced epoxy resin (EP) and their carbon-fiber composites (IMFs/CFRP) were fabricated. The effects of IMF on the mechanical properties of the EP and CFRP composites were studied. Infrared spectroscopy and scanning electron microscopy (SEM) were used to characterize the functional groups and microstructure of IMF, EP, and CFRP. The experimental results showed that the strength of the EP increased as the IMF content increased from 0% to 20%, but on further increase in IMF content of 25%, the strength of the EP reduced. In addition, the mechanical properties of the IMF/CFRP were slightly higher as compared with the control CFRP. The SEM observations on IMFs/EP and IMFs/CFRP composites reveal that the alkali-treated IMFs facilitate the interfacial interlocking structure and improve the interfacial adhesion of the composites.

天然竹叶添加量对环氧树脂及环氧-碳纤维复合材料力学性能的影响

摘要本研究通过物理处理和碱性处理，从天然竹叶中提取竹叶微纳米纤维(IMFs)。制备了IMFs增强环氧树脂(EP)及其碳纤维复合材料(IMFs/CFRP)。研究了IMF对EP和CFRP复合材料力学性能的影响。利用红外光谱和扫描电镜(SEM)对IMF、EP和CFRP的官能团和微观结构进行了表征。实验结果表明，IMF含量从0%增加到20%，EP强度随IMF含量的增加而增加，但当IMF含量进一步增加到25%时，EP强度降低。此外，与对照CFRP相比，IMF/CFRP的力学性能略高。对IMFs/EP和IMFs/CFRP复合材料的SEM观察表明，碱处理后的IMFs促进了复合材料的界面联锁结构，提高了复合材料的界面附着力。

期刊介绍： e-Polymers is a strictly peer-reviewed scientific journal. The aim of e-Polymers is to publish pure and applied polymer-science-related original research articles, reviews, and feature articles. It includes synthetic methodologies, characterization, and processing techniques for polymer materials. Reports on interdisciplinary polymer science and on applications of polymers in all areas are welcome. The present Editors-in-Chief would like to thank the authors, the reviewers, the editorial staff, the advisory board, and the supporting organization that made e-Polymers a successful and sustainable scientific journal of the polymer community. The Editors of e-Polymers feel very much engaged to provide best publishing services at the highest possible level.
