Morphological Study of Banana and Hemp Fiber Reinforced Nano-Titanium Oxide Composite Using Scanning Electron Microscope

In recent years, the technological applications related to natural fibers and nano-fillers reinforced hybrid composites have gained popularity due to suitable composite properties, fiber durability and eco-friendly nature. In this investigation, the outcome of different percentages of nano-titanium oxide (NTiO2) fillers at weights of (2%, 4%, and 6%) on banana-hemp fiber reinforced composite is analyzed using scanning electron microscope (SEM). As per the ASTM standards, banana and hemp fibers are trimmed to an average size of 32 mm. The SEM analysis is conducted in scanning mode, employing traditional SEM methodologies. The equipment utilized possesses a magnification range from 10X to approximately 40000X, a spatial resolution between 50 nm and 100 nm, and an acquisition speed ranging from 30 seconds to 60 seconds. The rheological and interfacial study is examined using SEM to analyze voids, fracture, delamination, and fiber pull out. The SEM images of banana-hemp fiber composite reinforced with 4% NTiO2 filler shows minimal fiber pull-outs, de-laminations, and a reduced quantity of voids compared to the composites reinforced with 2%, and 6% NTiO2 filler. The analytical modelling of the hybrid composite investigated in this research has been conducted and compared with the previous literature, in our previously published research [Saxena, T., & Chawla, V.
