Forces of flexural and tensile characteristics with nano cobalt filler in Carbon/Pineapple Leaf fiber composites

Composite materials are gaining popularity due to their better mechanical qualities and low weight. This study focuses on enhancing forces of flexural and tensile characteristics in epoxy-based composites by incorporating reinforced carbon fibers extracted from pineapple leaves in combination with cobalt filler. The reinforcement of natural fibers in composite materials addresses environmental concerns and contributes to improved mechanical attributes. Hand lay-ups of pineapple leaf fiber (PALF) and epoxy compound by carbon fiber were created proportion of weight (wt%) by adjusting cobalt 0.25 to 1.0 wt%. The flexural strength of PALF is around 101 MPa, and the Tensile strength of PALF is around 92.94 MPa. Whereas the Flexural strength of CF is around 343.54 MPa, and the Tensile strength of CF is around 181.32 MPa. Compared to pure epoxy, 51.25% increased strength and considerable improvement of flexural and tensile specimens. 0.5 wt% inclusion of nano Cobalt filler component confirms favorable strength test findings in PALF/CF epoxy combination. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.
