Title Rolling composite containing slot laminated composite material technology research
Abstract In this paper,by using DEFORM -3D under the different pressure rolling composite 7075Al/T2Cu/7075Al stack layer composite material bite and composite process are analyzed and actual cold rolling composite prepared 7075Al/T2Cu/7075Al laminated composite materials and characterization, to explore binding mechanism of the composite interface to discuss the research on effect of bonding strength. Mainly draw the following conclusions: The simulation results show that wedge plate material is conducive to the roll bite; with the increase of amount of reduction, 7075 aluminum between the initial combination can achieve, but the interface shear to tensile stress will increase, will increase between the sheet metal deformation coordination, resulting in the initial combination of interface is damaged and may lead to complex failed; if rolling composite when not in the slot add filler, the groove will also because of the deformation is destroyed, can not form the ideal trough. At room temperature when the pressure was more than 60%, 7075 aluminum alloy plate can be combined, the bonding strength increased firstly, but when the pressure exceeds 70%, decreased the binding strength, mainly is because the larger the amount of the pressure, so in cold rolling and compression amount to 70%.
