植物纤维增强树脂基复合材料界面纳米化改性的研究进展及应用

Research Progress and Application of Interfacial Nano-modification on Natural Fiber Reinforced Resin Matrix Composites

植物纤维是一种来源广、价格低的可生物降解材料,以植物纤维代替传统的合成纤维增强复合材料可有效缓解环境压力。然而,植物纤维与树脂基体的界面不相容限制了植物纤维增强复合材料(PFRP)的广泛应用。对PFRP进行界面改性可以有效增强其界面结合,从而提高复合材料的综合性能。传统的物理改性和化学改性对植物纤维自身有一定损伤,影响复合材料的力学性能。因此,本文综述了近年来国内外PFRP界面纳米化改性的研究进展,首先介绍了植物纤维的物理构造与化学组成,其次详述了PFRP界面纳米化改性方法,最后总结了界面表征方法和应用,并对今后PFRP界面纳米化改性的相关问题提出建议。

Natural fiber is a biodegradable material with a wide range of sources and low price,which could effectively relieve the environmental pressure when used in place of traditional synthetic fiber to reinforce composites.However,there is an obvious limitation in the wide application of plant fiber reinforced composites due to the mismatched polarity between natural fiber matrix and resin.Effectively optimized interfacial adhesion between natural fibers and polymer matrix could be achieved by interface modification,with comprehensive properties of the composites improved.It is reported that traditional physical modification and chemical modification could damage the plant fiber and affect the mechanical properties of the composites.Thus,this paper reviews the research progress on the interfacial nano-modification with mid reaction conditions of natural fiber reinforced composites in recent years.Firstly,we introduces the physical structure and chemical composition of natural fibers briefly.Secondly,it is necessary to describe the interfacial nano-modification methods of natural fiber reinforced composites in detail.Finally,the interfacial characterization methods and practical applications of natural fiber reinforced composites are illustrated,and the future development trend about the interface modification of natural fiber reinforced composites are prospected reasonably.
