天然纤维是一种经济的材料，由于其密度低，加工时无磨损，可生物降解，常用于各种应用。但是，由于其综合性能较低，其在各种应用中的使用仍然受到限制。可接受的改善纤维性能的方法是通过化学处理方法，该方法成本高，工艺细致，能源需求高。因此，开发了一种新的、简单且具有成本效益的纤维涂层处理方法，该方法能够改善物理和形态特性，为天然材料在更稳健的应用中的使用开辟了新的途径。在这项研究中，各种涂层红麻纤维的物理和形态学特性进行了分析，以了解涂层纤维的切割行为后，进行粉碎过程。在固化之前，将洋麻纤维分别浸入1：4、1：5和1：6的环氧树脂与丙酮涂料溶液中，并使用5mm、1mm、0.5mm和0.25mm筛孔连续粉碎。用偏光显微镜和扫描电镜分析了其形态特征。结果表明，1：6的包覆比溶液能有效地包覆纤维的长径比，形成长纤维长度的单根包覆纤维。此外，低粘度的1：6溶液能够渗透到纤维结构中，这通过密度和纤维横截面分析来支持。在未来，这种分析是至关重要的，以了解涂层纤维的行为后，受到机械手段的切割过程，后来涉及到复合材料样品中的增强机制。
Natural fibre is an economical material that often used in various applications due to its low in density, non-abrasiveness in processing and biodegradable. But, its usage in various applications is still limited due to the low in overall properties. The acceptable method to improve the properties of the fibres is by chemical treatment method that is costly, meticulous process and high energy demand. Thus, a new, simple and cost-effective fibre coating treatment method was developed which was able to improve the physical and morphological properties that open a new path for natural based materials to be used in a more robust application. In this study, the physical and morphological properties of various coated Kenaf fibres were analysed to comprehend the cutting behaviour of coated fibres after subjected to the pulverisation process. The Kenaf fibres were individually immersed in 1:4, 1:5 and 1:6 epoxy to acetone coating solutions prior cured, and pulverised consecutively using 5 mm, 1 mm, 0.5 mm and 0.25 mm mesh sizes aperture. The morphological characteristic was analysed using polarised optical and scanning electron microscope. The result showed that 1:6 coating ratio solution able to effectively coat the fibres’ aspect ratio that forming individual coated fibre which in long length pulverised fibres. Moreover, the low viscous 1:6 solution able to penetrate inside fibre structure that supported by density and fibre cross-section analysis compare to the other solutions. In future, this analysis is crucial to give insight on the coated fibres behaviour after subjected to the mechanical means of cutting process that later relates to the reinforcing mechanism in the composite samples.
