Effect of African Teff Fiber Loading on Mechanical Properties of Snake Grass and Glass Fibers Reinforced Epoxy Hybrid Composites

K Manickaraj, R Ramamoorthi, S Sathish, M Makeshkumar

Abstract

Natural fibers reinforced composites (NFRC) have been used in several industrial applications due to its strength to weight ratio, cost effectiveness, resistance to corrosion and fatigue and ease of fabrication. The plant fibers such as African teff and snake grass fibers have the prospective features to be used as an alternative elucidation for sustainable materials. The hybrid composites were fabricated by compression moulding technique with the varying weight fraction of natural fibers such as snake grass and African teff fiber (5% to 25%) into constant glass fiber (10%) and epoxy matrix (60%).The mechanical properties of prepared composite samples were performed as per ASTM standards. The results revealed that the composite with 20 wt% African teff fiber exhibits higher mechanical properties compared to other composites, due to improved surface properties of treated African teff fiber resulted in enhanced adhesion between fiber and matrix. Beyond 25 wt% African teff fiber reduced the composite performance due to fiber pullout and voids which confirmed by Scanning Electron Microscope (SEM) analysis.
