Performance of fiber metal laminate composites embedded with AL and CU wire mesh

Abstract

This work was investigated that the effect of aluminium (Al) and copper (Cu) wire mesh embedded as a structural reinforcement on jute epoxy hybrid composite. The hybrid composites were prepared by epoxy LY556 with HY951 hardener as a matrix; jute and wire mesh as reinforcements using the compression molding technique. In hybrid composites, the aluminium wire mesh (AWM) and copper wire mesh (CWM) were embedded as 45° & 90° orientation to the jute fiber (AWM45/90 and CWM45/90). The performance of the fabricated hybrid composites was studied by conducting various mechanical, thermal, and dynamic characterizations. The test results were shown that the tensile strength of the fabricated composite was improved by 14.12% in AWM45 and 9.28% in CWM45 compared to AWM90 and CWM90 composites respectively. The TGA result expressed that the thermal stability of the CWM45 composite was enhanced with the residue of 18.33% at 800 °C due to the influence of Cu-wire mesh. In the transition region, the 45° oriented wire mesh improved the loss modulus (E″) peaks about 31.74% in CWM and 11.49% in AWM composite to 90° oriented mesh.
