Natural fibre reinforced polymer composite has many industrial applications especially in automobile. However low mechanical and thermal property has limited its application. In this study, natural fibre reinforced hybrid nanocomposite was manufactured by the incorporation of high frequency microwave treated Plantain (Musa paradisiaca) fibre and multiwalled carbon nanotubes (MWCNT) using a single epoxy resin matrix. The consequence of harmonized existence of MWCNT at different loading (0.5−2 wt.%) on the physical, mechanical and thermal Properties of the hybrid nanocomposite was examined, using the ultrasonic technique for dispersion of nanoparticles and hand lay-up and compression moulding process for composite production. The experimental results demonstrate that the mechanical properties strength improve up to 52%, while up to 30% improvement was recorded for micro-hardness and impact strength, caused by increment in MWCNT content. Scanning electron microscope (SEM) analysis reveals good mechanical dovetailing of hybrid fibres with polymer matrix. Thermal conductivity has shown significant improvement up to 43% as MWCNT contents increases. These enhancements are primarily ascribed to the high aspect ratio, high modulus, strength and good dispersal of carbon nanotubes (CNT) in the hybrid nanocomposites.

天然纤维增强的聚合物复合材料具有许多工业应用，尤其是在汽车中。然而，低的机械和热性能限制了其应用。在这项研究中，通过掺入高频微波处理的车前草（Musa paradisiaca）制造了天然纤维增强的杂化纳米复合材料。纤维和多壁碳纳米管（MWCNT）使用单个环氧树脂基质。使用超声技术分散纳米颗粒并进行手工铺层和压塑工艺，研究了不同负载量（0.5-2 wt。％）下MWCNT的协调存在对杂化纳米复合材料的物理，机械和热性能的影响。用于复合材料生产。实验结果表明，由于MWCNT含量的增加，机械强度提高了52％，而显微硬度和冲击强度提高了30％。扫描电子显微镜（SEM）分析显示，杂化纤维与聚合物基质的机械吻合良好。随着MWCNT含量的增加，导热率已显示出高达43％的显着提高。
