The purpose of this paper is to discuss the concept of green composite in automotive part replacement. Adaptation of lightweight materials in transport system has been an integral part of weight saving measures in car's component formation. The continuing rise in ambient temperature is a signal no scientist would ever ignore in the face of global warming and attendant water level surge. Reduction of body system of automobile vehicles has been ongoing for several years with huge patronage on synthetic materials. The sudden attention to green composite may not be unconnected with the environmental impact of vehicular materials after their life cycle. This has led to the improved properties of polymeric materials to replace ferrous and nonferrous metals in vehicle formation. In this paper, an in-depth study was undertaken on sustainable green materials limiting the scope on the plant fibre for automotive part replacement. Plant fibres are increasingly gaining momentum in view of their recyclability and environmental friendliness. It has been noted that nearly all automakers are exploring the recyclable or biodegradable materials for part replacement, making the green composite a material for the future. Part of the attracting properties of plant fibres is their relative high strength and stiffness with low cost and low CO emission. This is also, in addition, to their biodegradability and renewability. Further discussion in this paper centred on the difficulty in the modification of plant fibre for sustainable compatibility in part formations. Key of the conclusions drawn from this work indicates a promising future for plant fibres with enormous challenges relating to their chemical treatment.
本文旨在探讨汽车零部件更换中绿色复合材料的概念。在运输系统中采用轻质材料已经成为汽车零部件减轻重量措施的一个组成部分。面对全球变暖以及随之而来的水位上升,环境温度的持续上升是任何科学家都不会忽视的信号。几年来,汽车车身系统一直在不断减少,对合成材料的大量使用也在不断增加。人们突然关注绿色复合材料,可能与车辆材料在生命周期结束后的环境影响不无关系。这导致了聚合物材料性能的提高,以替代汽车制造中的黑色金属和有色金属。本文对可持续绿色材料进行了深入研究,将研究范围限于用于汽车零部件更换的植物纤维。鉴于植物纤维的可回收性和环境友好性,它们的应用越来越广泛。据指出,几乎所有的汽车制造商都在探索可回收或可生物降解的材料用于零部件更换,使绿色复合材料成为未来的材料。植物纤维吸引人的部分原因在于其相对较高的强度和刚性,成本低,CO 排放量低。此外,它们还具有生物降解性和可再生性。本文进一步的讨论集中在植物纤维的可持续兼容性改性方面的困难。从这项工作中得出的结论表明,植物纤维具有广阔的前景,但也面临着与化学处理相关的巨大挑战。
