Abstract

Natural ﬁber polymer composites are gaining focus as low cost and light weight composite material due to the availability and ecofriendly nature of the natural ﬁber. Fiber composites are widely used in civil engineering, marine and aerospace industries where dynamic loads and environmental loads persist. Dynamic analysis of these composites under diﬀerent loading and environmental conditions is essential before their usage. The present study focuses on the dynamic behavior of areca nut husk reinforced epoxy composites under diﬀerent loading frequencies (5 Hz, 10 Hz and 15 Hz) and diﬀerent temperatures (ranging from 28 ◦ C to 120 ◦ C). The eﬀect of loading and temperature on storage modulus, loss modulus and glass transition temperature was analyzed. Increase in storage modulus is observed with increase in loading frequency. The storage modulus decreases with increase in temperature. The glass transition temperature of the composite is determined to be 105 ◦ C. The elastic modulus calculated from the DMA data is compared with three point bending test.

槟榔壳纤维增强环氧树脂复合材料的动态力学性能

天然纤维聚合物复合材料由于其可获得性和环保性而成为低成本、轻量化的复合材料。纤维复合材料广泛应用于持续存在动载荷和环境载荷的土木工程、船舶和航空航天工业。在使用这些复合材料之前，必须对其在不同载荷和环境条件下进行动态分析。本文主要研究槟榔壳增强环氧复合材料在不同加载频率(5 Hz, 10 Hz和15 Hz)和不同温度(28℃至120℃)下的动态性能。分析了载荷和温度对储存模量、损耗模量和玻璃化转变温度的影响。存储模量随加载频率的增加而增加。存储模量随温度的升高而降低。复合材料的玻璃化转变温度确定为105°C。将DMA数据计算的弹性模量与三点弯曲试验进行了比较。

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.
