Abstract
A flat roll bonded composite material based on aluminum matrix and reinforcing steel mesh inlets can be applied in aero-space, automotive, train, ship building, and household industries. However, the development of its manufacturing technology requires complete understanding of transformation of its components during the roll bonding process as well as an impact of technological parameters on its bonding quality. Thus, bonding properties between aluminum clad layers AA6060 and steel meshed reinforcement inlets AISI 304 (expanded sheet) and ASISI 321 (wire mesh) of roll-bonded reinforced composite have been investigated in this study. The applied reduction was 30 and 20 %, the temperature of the roll bonding process was 500 and 400℃, the temperature of the heat treatment process was 520℃ with holding time 45 minutes. During the peel test, the destruction of inlets was observed in all cases, therefore, no data were obtained regarding the correlation between the reduction magnitude and the peel strength. At the same time, the effect of temperature and heat treatment on the bonding strength between layers have been studied by means of peel test. In addition, a simulation of the hot roll bonding process of aluminum with expanded mesh inlets was developed using the finite element method (FEM) via QForm software. Conditions of FEM simulation corresponded to experimental ones and the simulation was verified with the experiment by the comparison of deformation parameters of whole composites and angles between strands during the opening of expanded mesh cells.
