Introduction Nano composite materials have been performing a significant role in lightweight structures for aerospace, automotive, defense, railway and marine applications. This is owing to their outstanding properties such as less weight, low cost, high stiffness and strength, corrosion resistance and resistance to thermal expansions for replacing A.

traditional metals [1–3]. Ecological and public concerns are encouraging the leading researchers and scientists to design and examine novel materials with enhanced properties for automotive structural applications. Such materials have an enhanced eco-friendly characteristics and an improved load-carrying capability [4, 5]. In this context, the nano filler reinforced bio fiber polymer composites are desired owing to their lightweight, recyclability and noticeable mechanical properties [6–8]. In this regard, the previous researchers have examined the mechanical performance of bio fiber polymer matrix composites reinforced with the various nano particles obtained from organic and inorganic sources [9, 10]. The particles like barium sulfate, kaolin, magnesium hydroxide, zinc oxide, etc., are inorganic nano fillers. Conversely, the cellulosic nano fillers such as coir, fly ash, nutshell powders, rice husk, carbon black derived naturally signify organic nano fillers. For instance, Hakamy et al. [11] examined the effect of calcined nanoclay fillers on the tensile properties of mercerized hemp fabric reinforced polymer composites. They reported that the tensile properties were enhanced by the addition of calcined nanoclay (CNC). Praveen Kumar et al. [12] examined the influence of nano fillers on the tensile strength of alkaline treated kenaf fabric reinforced epoxy composite and concluded that inclusion of nano fillers in polymer matrix can improve the tensile properties, but decreased the moisture resistance. From the aforementioned literature studies, it was perceived that the inclusion of nano fillers in natural fabric composites had both merits as well as effects on enhancing the mechanical characteristics of the composite. As a result, it is significant to determine the selection of nano fillers and their proportion for its competent utilization to acquire the preferred characteristics. But, there were limited research studies available in the previous literature [13, 14] which investigated the influence of multi-walled carbon nanotubes on the tensile and
