Abstract

The use of natural particles as reinforcement in polymers has been a growing research area. This study aims to explore the use of cassava back peel (CCBP) and iron-fillings (IF), as reinforcement material in epoxy resin-based composite. Composite plates were prepared for the casting of the epoxy resin reinforced with CCBP and IF composites using a hand lay-up technique. The percentage compositions by weight of the CCBP varied between 0%-10 %, while that of IF was kept constant (5%). The physico-mechanical behaviours of CCBP-reinforced epoxy polymer composites were studied using ASTM standards. The density of the epoxy resin was improved by the reinforcements. The maximum density obtained was 1270 kg/cm3 for 5%CCBP epoxy composite. The percentage of water absorption improved by the addition of the filler with 5%IF10CCBP epoxy hybrid composite recording 30% water absorption. Conversely, the ultimate tensile strength (UTS) and breaking strength (BS) varied with the addition of the filler materials. 5%CCBP epoxy composite recorded 41.26 MPa for both UTS and BS. Meanwhile, percentage elongation decreased with the addition of the fillers showing that the composites became less ductile. The HBN of epoxy was improved with the addition of fillers. The composites can be applied to automobile dashboards.

用碳化木薯背皮和铁填料增强的聚合物基复合材料的物理力学性能

在聚合物中使用天然颗粒作为增强材料一直是一个不断发展的研究领域。本研究旨在探索木薯背皮（CCBP）和铁填料（IF）在环氧树脂基复合材料中作为增强材料的应用。采用手糊技术制备了复合板材，用于浇注木薯背皮和铁填料增强的环氧树脂复合材料。CCBP 的重量百分比在 0%-10% 之间变化，而 IF 的重量百分比保持不变（5%）。采用 ASTM 标准研究了 CCBP 增强环氧聚合物复合材料的物理机械性能。增强体提高了环氧树脂的密度。5%CCBP 环氧树脂复合材料的最大密度为 1270 kg/cm3。添加填料后，5%IF10CCBP 环氧混合复合材料的吸水率提高了 30%。相反，极限拉伸强度（UTS）和断裂强度（BS）随填充材料的添加而变化。5%CCBP 环氧复合材料的极限拉伸强度和断裂强度均为 41.26 兆帕。同时，百分比伸长率随填充物的添加而降低，表明复合材料的韧性降低。添加填料后，环氧树脂的 HBN 得到改善。该复合材料可应用于汽车仪表板。

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.
