Biocomposite materials manufactured from natural fibres and polymer matrix represent a group of engineered composite products with diverse applications. These materials continue to find increasing applications due to their design flexibility, superior properties and aesthetic appeal. The applicability of these biocomposites, however, depends on the interaction in the fibre-matrix interface. This paper reviews the state of the art research in fibre-matrix interfacial interaction based on published literature. A brief background on biocomposite materials is presented. The focus of this review is the modification of natural fibres and its effect on fibre-matrix interfacial adhesion and properties. In addition, the effect of chemical treatment on fibre composition and fibre-matrix interfacial bonding mechanism are discussed.

由天然纤维和聚合物基质制成的生物复合材料代表了一组具有多种应用的工程复合产品。这些材料由于其设计的灵活性，优越的性能和美学吸引力而不断得到越来越多的应用。但是，这些生物复合材料的适用性取决于纤维-基质界面中的相互作用。本文根据已发表的文献综述了纤维-基质界面相互作用的最新研究进展。介绍了生物复合材料的简要背景。这篇综述的重点是天然纤维的改性及其对纤维-基质界面粘合和性能的影响。此外，还讨论了化学处理对纤维成分和纤维-基质界面结合机理的影响。
