摘要

摘要本研究的目的是评估基于氢氧化钠(AT)、碳酸钠(ST)和碳酸氢钠(SHT)的低成本、环保的黄麻纤维化学改性对黄麻纤维增强环氧复合材料(JFREC)形态、吸水率、力学和摩擦学特性的有效性。与未经处理的JFREC相比，AT JFREC(38.08%、30.56%和31.66%)、ST JFREC(70.03%、33.06%和41.30%)和SHT JFREC(24.69%、8.88%和22.61%)的抗拉强度、抗拉模量和冲击强度等力学性能均有明显改善。实验结果还证实，化学改性后的JFREC与纤维基体的粘附性得到改善，从而提高了JFREC的吸水性和摩擦学性能。通过化学改性的JFREC获得了更好的机械和摩擦学性能，可以在汽车和包装工业中找到潜在的应用。

Mechanical and tribological properties of chemically modified jute/epoxy composites

ABSTRACT The purpose of the present work is to assess the effectiveness of low-cost and environmental friendly chemical modification of jute fibres based on the usage of sodium hydroxide (AT), sodium carbonate (ST) and sodium hydrogen carbonate (SHT) on the morphological, water absorption, mechanical and tribological characteristics of jute fibre-reinforced epoxy composites (JFREC). Mechanical properties like tensile strength, tensile modulus and impact strength showed appreciable improvement for the AT JFREC (38.08%, 30.56% and 31.66%), ST JFREC (70.03%, 33.06% and 41.30%) and SHT JFREC (24.69%, 8.88% and 22.61%) when compared to untreated JFREC. The experimental results also confirmed that the improved fibre-matrix adhesion, attained by chemical modification, increased the water absorption resistance and the tribological properties of chemically modified JFREC. Improved mechanical and tribological properties attained by the chemically modified JFREC can be found as a potential application in automotive and packaging industries.

期刊介绍： Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
