Abstract:The hot-roll bonding is a key procedure to produce high damping laminate aluminium alloy sheets. The influences of hot-roll bonding technologies involving heating temperature, holding time, total reduction ratio and reduction ratio per operation on interfacial bonding strength of various layers in the composite were studied by means of orthogonal test method. The interfacial characteristics between various bonding layers were analysed with metalloscope and scanning electron microscope. The optimum technologies for manufacturing hot-roll bonding high damping laminate aluminium alloy sheets were determined, that is, heating temperature 350℃, holding time 1 h, total reduction ratio 75%, summary reduction ratio of the first and second operations 35%.
Key words: damping materials hot-roll bonding bonding strength interfacial characteristic
