Sustainable development and conservation of agro‐waste coconut shell powder strengthen lightweight aluminum bio‐composite for user friendly

Abstract

The sustainable growth of advanced material in metal matrix composites receiving the eco‐friendly hazard‐free composite via recycling waste agro products attains low fabrication cost. The prime goal of this investigation is to develop and strengthen the lightweight aluminum alloy (Al7075) composite through the conservations of 0 wt%, 5 wt%, 10 wt%, and 15 wt% agro‐waste coconut shell using squeeze cast technology. The developed aluminum alloy bio‐composites are promising the best option for replacing conventional metals in several engineering applications like automotive, structural, aerospace, and others. The synthesized Al7075 alloy bio‐composites are studied its physic‐mechanical behavior tag with ASTM standards. The density results revealed nominal improvement, and its mechanical properties of hardness, ultimate tensile strength, and elastic modulus increased significantly. Sample 4 composite contained 15 wt% coconut shell powder found 2.82 ± 0.17 g/cc density with 0.716% porosity level enhanced the hardness, Ultimate tensile strength and elastic modulus of 79 ± 1.1Hv, 238 ± 1.1 MPa and 77.89 ± 2.01 GPa, respectively.
