Study of Samples of Aluminum Reinforced with Hollow Copper Spheres Obtained by Casting

Analysis of the mechanical behavior of aluminum reinforced with metallized spheres is carried out. Samples of reinforced aluminum obtained by improved casting technology are tested for bending. The role of metallized spheres in resistance to deformation is studied. The dependence of the bending strength on the diameter of the reinforcing spheres is determined. It is established that the use of spheres of minimum size is preferable, since the maximum load is achieved with low deformation and elongation of the sample. The use of polystyrene foam spheres coated with a copper–graphite layer results in a lightening of the product by up to 30% of the total weight.
