A comparative review of Nettle and Ramie fiber and their use in biocomposites, particularly with a PLA matrix

ABSTRACT

Current environmental concerns are increasingly forcing manufacturers to reduce the use of petroleum derivatives in order to reduce their carbon footprint. The use of new plant-based materials is therefore an interesting alternative to plastics. A certain number of plant fibers have been rediscovered for use in the form of agro-composites; Nettle fiber is one of them. The objective of this review is thus to take stock of current knowledge on the European Nettle fiber (Urtica Dioica) and its asian version (Boehmeria nivea, or Ramie), which are too often confused. This “weed,” which has been used since antiquity, is coming back into fashion thanks to the highlighting of some of its properties but also to its simplicity of cultivation. The association PLA/Nettle, lending itself perfectly to this concept of modern ecological material 100% biodegradable, is also highlighted in this work where the intrinsic qualities of each component are detailed based on the promising uses of this agro-composite mentioned in the literature or the automotive industry.

摘要

当前的环境问题正日益迫使制造商减少石油衍生物的使用, 以减少碳足迹. 因此, 使用新的植物材料是塑料的有趣替代品. 一定数量的植物纤维已被重新发现, 以农用复合材料的形式使用; 荨麻纤维就是其中之一. 因此, 本综述的目的是总结关于欧洲荨麻纤维 (荨麻) 及其亚洲版本 (苎麻) 的最新知识, 这些知识经常被混淆. 这种“野草”自古以来就被使用, 由于突出了它的一些特性, 而且种植简单, 现在又重新流行起来. PLA/荨麻协会完美地体现了100%可生物降解的现代生态材料的概念, 在本研究中还强调了每种成分的内在质量, 并根据文献或汽车行业中提到的这种农用复合材料的潜在用途进行了详细说明.
