Fabrication and characterization of Neem leaves waste material reinforced composites

Abstract

Neem materials are used in the recyclable material field when the manufacturer needs to increase the strength and decrease the weight of a structure. It offers both mechanical and thermal properties. Moreover, anepoxy recycled Neem composite made with epoxy and hardener exhibited greater impact toughness, with a maximum value of 12.32 J/m. The present research has been conducted in an attempt to develop materials incorporating recycled Neem composites that have improved thermal stability for commercial use for essential purposes. Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) were the techniques used to determine recycled Neem composites' thermal properties, such as energy loss, weight loss, etc. X-ray diffraction (XRD) analysis determined that the crystallinity was 58.67%, and the average grain size was 5.34 nm. Scanning electron microscopy with Energy-dispersive X-ray spectroscopy (SEM + EDS) was used for elemental analysis yielding, for example, C 54.30% and Ca 5.99%. FTIR spectroscopy was used for the structural study and morphology of Epoxy-Neem Recyclable Composite (ENRC) reinforced materials. The peak in the spectrum at 1750 cm-1was assigned to the nitrile groups. The different significant effects of recycled Neem waste composite properties were studied to stimulate the recycling of materials and to determine the potential of using recycled waste in composites.
