Experimental Study of Composites and Metal-Wire Joints

Abstract

In order to join a composite structure to a metallic structure, the metal-wire layers were co-cured with composite layers using the Vacuum Assisted Resin Transfer Molding (VARTM). Then, the interface fracture strength was measured for Mode II fracture for various lay-up and interface conditions. The study includes a metal-wire to composite interface, composite to composite interface, and metal-wire to metal-wire interface. In addition, the lay-up orientations of the metal-wires were varied between 0 and 90 degrees. The study also examined the crack propagation from a composite to a metal/composite interface. During the test, the Digital Image Correlation (DIC) technique was applied to capture the strain field around the crack tip. The results suggested that a metal-wire/composite laminate would be effective to connect a composite structure to a metallic structure.
