Evaluating the Engineering Properties of Conductive Bio-Composite for Mechanical And Computer Installations Design

Abstract

This research focused on the production of conductive composite (CC) by using recycled agricultural residues and carbon-based materials. Five CC samples were created by combining carbonized periwinkle shells ash (PSA) and recovered graphite (SGr) from battery products using the hand lay-up method, with epoxy serving as the matrix. The mechanical and electrical properties of the CC were assessed following approved procedures outlined by ASTM International. It was noted that the laboratory test results indicated that both PSA and SGr, considerably influenced the tensile strength and electrical conductivity (EC) of the composite samples. The tensile strength increased from 89 to 110 MPa was the PSA volume increased from 10 to 16% (by % mass of the matrix). Similarly, the EC of the composites showed a tendency to increase from 0.0065 to 0.074 s/cm, as the PSA integrated into the composite the composite rose from 10% to 16%. Results obtained from this experiment indicated that recycled agricultural waste materials and recovered graphite can be effectively utilized to produce conductive composites. These composites hold promise for applications in manufacturing sensitive electronic devices and aircraft components
