Abstract For the past 15 years, there has been tremendous interest and technological development concerning biocomposites. Plant fibres can be derived from a multitude of natural agro-sources, with the preferred choice as a composite reinforcement often being driven by abundance, geographical location, and historical use. While from a product designer's or engineer's point of view, all plant cell walls are 'similar', they have indeed substantial morphological and mechanical diversity linked to their structure, biochemical composition and the plant growing conditions. Here, we provide a holistic overview of the main types of plant cell walls used as polymer reinforcements. The relationship between their structures and properties, in constant link with potential associated composite, is specifically discussed. Then, the fibre extraction and cultivation modes are compared, through an environmental assessment. We also show how a scientist's point of view on cell wall structure and associated experimental approach lead to distinct results; following a critical review, we make recommendations on appropriate characterisation. A final discussion highlights the pertinent parameters that accurately define a composite reinforcement fibre. The review will serve as a handbook reference for researchers and designers in the field of biomaterials for appropriate selection of plant cell walls for specific composite applications.

高性能植物纤维复合材料的设计：我们如何最好地定义植物细胞壁的多样性和特异性？

摘要 在过去的 15 年中，人们对生物复合材料产生了巨大的兴趣和技术发展。植物纤维可以来自多种天然农业资源，作为复合增强材料的首选通常取决于丰富度、地理位置和历史用途。虽然从产品设计师或工程师的角度来看，所有植物细胞壁都是“相似的”，但它们确实具有与其结构、生化成分和植物生长条件相关的大量形态和机械多样性。在这里，我们提供了用作聚合物增强材料的主要植物细胞壁类型的整体概述。特别讨论了它们的结构和性能之间的关系，与潜在的相关复合材料的持续联系。然后，通过环境评估比较了纤维提取和种植模式。我们还展示了科学家对细胞壁结构和相关实验方法的看法如何导致不同的结果；经过严格审查，我们就适当的特征提出建议。最后的讨论强调了准确定义复合增强纤维的相关参数。The review will serve as a handbook reference for researchers and designers in the field of biomaterials for appropriate selection of plant cell walls for specific composite applications. 我们就适当的特征提出建议。最后的讨论强调了准确定义复合增强纤维的相关参数。The review will serve as a handbook reference for researchers and designers in the field of biomaterials for appropriate selection of plant cell walls for specific composite applications. 我们就适当的特征提出建议。最后的讨论强调了准确定义复合增强纤维的相关参数。The review will serve as a handbook reference for researchers and designers in the field of biomaterials for appropriate selection of plant cell walls for specific composite applications.
