Abstract

Abaca fibres that have excellent mechanical properties are widely applied in the production and preparation of eco-friendly polymer composites as reinforcement materials. However, the weak interfacial bonding property of the abaca fibre and composite matrix limits the further extended application of abaca fibre-reinforced polymer composites. In this research, the findings demonstrate that, compared to raw abaca fibres, the interfacial shear strength (IFSS) value between the treated fibre and matrix is improved by 32% to 86%. Moreover, chemically treated abaca fibres could not only improve the wear resistance of the polymer composites, but also could promote the formation of primary and secondary plateaus. The best wear resistance behaviour was demonstrated by the sample with abaca fibres treated with 3% NaOH and 5% silane solutions, which had a maximum reduction in the sum wear rate of 28.44%. This research will provide detail on theoretical guidance and technical support for the development of eco-friendly natural fibre-reinforced polymer composites.

摘要

具有优异机械性能的马尼拉麻纤维作为增强材料被广泛应用于环保型聚合物复合材料的生产和制备中。然而，马尼拉麻纤维与复合基体之间较弱的界面粘结性能限制了马尼拉麻纤维增强聚合物复合材料的进一步广泛应用。在本研究中，研究结果表明，与未处理的马尼拉麻纤维相比，处理后的纤维与基体之间的界面剪切强度（IFSS）值提高了32%至86%。此外，化学处理的马尼拉麻纤维不仅可以提高聚合物复合材料的耐磨性，还可以促进一级和二级平稳段的形成。用3%氢氧化钠和5%硅烷溶液处理的马尼拉麻纤维样品表现出最佳的耐磨性能，其总磨损率最大降低了28.44%。本研究将为环保型天然纤维增强聚合物复合材料的开发提供详细的理论指导和技术支持。
