Purpose. To quantitatively analyze the deformation of kirigami-type deformable inlays during the roll bonding process using soft outer matrices, with the goal of predicting their behavior within the composite structure. Methodology. The research involved the fabrication of three-layer composite sheets through roll bonding. Expanded meshes made of mild steel and stainless steel served as the inlay phase, while copper and aluminum alloy sheets were employed as matrix materials. The transformation of the inlay phase within the composite sheets was evaluated. Findings. The experimental investigation yielded data on the deformation behavior of kirigami-type inlays embedded within three-layer sheets during roll bonding. It was observed that using an aluminum matrix induces greater axial metal flow in the deformation zone, leading to a significant increase in the mesh distortion angle. A copper matrix primarily causes flattening of the mesh cells with minimal changes to their angular deformation. In contrast, rolling the steel mesh without a matrix results in negligible angular distortion until the rolling reduction exceeds 50 %. Originality. This study represents the first quantitative analysis of the geometric transformation of kirigami-type deformable inlays as a function of deformation magnitude and matrix material properties during roll bonding. Understanding the shape transformation of the reinforcing phase within the composite sheet enables more accurate prediction of the contact area between the matrix materials during the bonding process. Practical value. The findings of this research provide a basis for predicting the final geometry of kirigami structures within composite materials. [ABSTRACT FROM AUTHOR] |
