The study is devoted to the analysis of behavior of reinforcing inlay at roll bonding of aluminium composite with deformable steel mesh inside during both experimental and numerical simulation procedure. A composite material based on outer sheets of a EN AW 1050 aluminum alloy and an inner core of expanded AISI 304 steel mesh was manufactured by hot roll bonding with a rolling reduction of 20%, 30%, 40% and 50% at 500 °C. A numerical simulation of the roll bonding process was performed with the finite element software QForm VX 8.2.3. The strain parameters of the composite material and its elements were studied, and the strain hardening of the expanded mesh core was analyzed via the Vickers hardness test. The evaluable parameters of the mesh deformation inside the composite such as: knuckle reduction, strand reduction, strand contraction as well as cell elongation were quantitatively described. The preferable rolling reduction range was established at current experimental conditions regarding to the inlay deformability. Described in the study composites shown enhanced fire resistance as well as peeling strenght compare to other similar roll bonded composites.

这项研究致力于在实验和数值模拟过程中分析内部嵌有可变形钢网的铝复合材料的辊压粘结补强嵌体的行为。基于EN AW 1050铝合金外层和扩展AISI 304钢网的内芯的复合材料是通过热轧粘合在500°C下压下率分别为20％，30％，40％和50％制成的。使用有限元软件QForm VX 8.2.3对辊压粘合过程进行了数值模拟。研究了复合材料及其元素的应变参数，并通过维氏硬度试验分析了膨胀网芯的应变硬化。复合材料内部网格变形的可评估参数，例如：折节减少，股线减少，定量描述了链的收缩以及细胞的伸长。关于镶嵌变形性，在当前的实验条件下确定了优选的压下率范围。研究中描述的复合材料与其他类似的辊压复合材料相比，具有更高的耐火性和剥离强度。
