Summary Bamboo, reformed to a plate form, has better mechanical properties than normal bamboo. Reformed bamboo/aluminum sandwich laminates were fabricated using an epoxy and a modified polyethylene as adhesives. Peel and lap-shear tests were performed to evaluate the bond strengths of the laminar interfaces. It was found that the reformed bamboo/aluminum laminates bonded with polyethylene had much higher peel and shear strengths than those bonded with epoxy. For the polyethylene bonded laminates, the fracture occurred mainly at the bamboo/adhesive interface and through the bamboo during peeling; while in shear the failure mode depended on which surface of bamboo, i.e., inner or outer bamboo surface, was bonded to the aluminum sheet. The major failure mechanisms in both peeling and shear were a combination of cohesive and interfacial failures. However, for the epoxy bonded laminates, the fracture occurred almost exclusively at the aluminum/epoxy interface, and the failure mechanism was interface-dominated.
