Abstract. This article is devoted to the investigation of technical process of reinforcement of aluminum sheets with wire for increasing equipment reliability for complex gas preparation.Reduction of operating coalmines forces to give more attention to gas and gas-condensate deposits. Before supplying gas to the pipeline, it must be cleaned from various impurities at special plants for complex gas treatment. Separating equipment, absorption or adsorption columns and other equipment used for these purposes, should be wear-resistant and lightweight and withstand high loads. Aluminum sheets with mesh reinforcement possess such properties. Actual task is improving of technology for obtaining such sheets in order to receive higher quality and reduce cost of the products. The article presents results of experimental studies of the strain parameters of rolling an aluminium matrix when wire mesh is inserted between aluminium layers. During the experiment, two types of stainless steel fabric meshes oriented parallel and diagonal to the rolling axis were placed between two aluminium strips and rolled. Rolling processes were performed, at which temperature and pressure on the material were varied to produce bonding of matrix layers. This study focused on measuring strain in areas of longitudinal and cross sections; stretching and ovalization of the wire mesh; measuring changes in the mesh angles of the cell; and testing mechanical properties of composites along the rolling direction. Main contradiction resulting from this experiment was as follows: contact pressure required for the bonding of aluminium layers produces extreme tensile strain on the inserted wire mesh, degrades mechanical properties of the reinforcing mesh and, thus, degrades properties of the entire composite. Optimal results in the longitudinal tension tests were achieved by using strips with diagonally oriented meshreinforcement. This study was supported by German Academic Exchange Service (DAAD) in the framework of German-Ukrainian project «Praxispartnershaft Metalurgie».
Keywords: aluminium matrix, steel mesh, reinforcing, rolling, delamination, mechanical properties.
