Subject(s): Online resources: Abstract: The role of adhesion between aluminum sheets and fiber composite prepreg on the mechanical property projiles of carbon-fiber-reinforced metal laminates (CFRMLs)has been investigated. Differences in adhesive bonding were achieved by using two different aluminum surface treatments, one with a standard P2-Etch procedure and another with a modified FPL-Etch procedure with the subsequent application of a silane coupling agent. Double-cantilever beam (DCB)tests were conducted to measure the interfacial fracture energy, and an increase in interfacial fracture toughness by up to six times was achieved by using the latter method. Optical and scanning electron microscopy were used to study the failure behavior and fracture mechanisms of the CFRMLs. No clear differences were found in laminate mechanical properties such as tensile strength and Young's modulus. A reduction of 10
