Abstract

In this article, a kind of green composite was prepared from recycled polypropylene (r-PP) which was further reinforced with various loadings of chemically modified bamboo fibres. Effects of bamboo fibre loading on the mechanical and thermal properties of r-PP/bamboo composites were studied. Those properties were characterized by tensile testing, impact testing, thermogravimetric analysis (TGA), and differential scanning calorimeter (DSC). Standardized test specimens with 0%, 10%, 20%, and 30% mass fractions of bamboo fibre were obtained by an extrusion process which was then finalized on injection molding. The experiment revealed the tensile strength and strain of the composite become greater with the increase of bamboo fraction in the ultimate value of 20% mass fraction. The composite with 10% bamboo fibre loading recorded the highest value of impact strength. Meanwhile, it was evident that the presence of bamboo fibre decreased the thermal stability of recycled polypropylene materials. Therefore, this composite material may find good potential for semi-structural loading applications in relatively low-exposure working.

再生聚丙烯竹纤维增强复合材料的机械和热性能

本文以再生聚丙烯(r-PP)为原料，用不同载荷的化学改性竹纤维对其进行增强，制备了一种绿色复合材料。研究了竹纤维载荷对r-PP/竹复合材料力学性能和热性能的影响。通过拉伸试验、冲击试验、热重分析(TGA)和差示扫描量热计(DSC)对这些性能进行了表征。通过挤压工艺获得竹纤维质量分数为0%、10%、20%和30%的标准化测试样品，然后进行注塑成型。试验结果表明，竹材掺量在20%质量分数的极值范围内，随着竹材掺量的增加，复合材料的抗拉强度和应变增大。当竹纤维负荷为10%时，复合材料的冲击强度最高。同时，竹纤维的存在明显降低了再生聚丙烯材料的热稳定性。因此，这种复合材料可能会在相对低暴露工作的半结构加载应用中发现良好的潜力。

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.
