Experimental Investigation on Thermal Behaviors of Benzoyl Treated Neem / Pineapple Fiber Reinforced Saw Dust Filled Epoxy Hybrid Green Composites

Natural fibers have in recent times turned into reasonable to automotive production as a substitute corroboration for synthetic fiber reinforced thermoplastics. This research was motivated by evolving and assessing benzoyl-treated Neem and Pineapple fiber reinforced and particulated by sawdust in hybrid epoxy polymers for automotive. Seven types of composites were fabricated using hand layup technique. The prepared composites were cut according to their ASTM standard. The Hybrid Neem and Pineapple Fiber Reinforced with Saw dust Particulated Epoxy Composite (NPFRSPEC) was studied for thermal analysis like Thermal Conductivity (TC), Coefficient of Linear Thermal Expansion (CLTE), Heat Deflection Temperature (HDT) and Thermal Gravimetric Analysis (TGA). Morphological analysis was done through FESEM on failure surfaces. The results reveal that treatment fibers enhanced the thermal stability among the non-treated composite. The treated fibers exhibited 10% increase in heat deflection temperature and 28% increase in thermal conductivity. From the results, it’s also noticed that the treated hybrid composite delivers better thermal efficiency when compared with other natural fiber-reinforced polymers available in the sector which could potentially replace long fiber reinforced thermoplastic components in car doors and bumpers.
