Roll Bonding of Steel Net-Reinforced Aluminium Strips

Two types of stainless steel fabric netting with different orientation to the rolling axis were placed between two aluminium strips and hot rolled. The rolling temperature and reduction were varied to achieve the sound bonding between the matrix layers and steel net.

During the study, the following main investigations were made: strain on areas of longitudinal and transverse cross sections of the composite was measured; stretching and ovalization of net wiring and changes in the net cell angles were determined; mechanical properties of composites along the rolling direction were tested. The experiments were summarized by following contradiction: the contact pressure, required for the bonding of aluminium layers, produces extreme tensile strain on the inserted wires, reducing the mechanical properties of the reinforcing net and, consequently, reducing the properties of the entire composite.
