MANUFACTURING AND DYNAMIC TESTING PROCESS FOR CARRYING OUT NEW TYPES OF LAMINATED COMPOSITE STRUCTURES COMPRISING HIGH ENTROPY ALLOYS (), STEEL RESISTANT TO STRAINS OF HIGH SPEED AND DEFORMATION ENERGY, CERAMICS AND POLYMERIC MATERIALS

摘要

The invention relates to laminated composite structures comprising one or two layers of high entropy alloys - HEA, including in their composition various metals: Al, Cr, Fe, Co and Ni in different percentages, and to a process for preparing the same, where the said structures are meant to be used in manufacturing materials for individual or collective ballistic protection against destructive factors, such as bullets, splinters, shock waves, knife blades and the like. According to the invention, the structures can be carried out in three versions, as follows: a. a HEA layer (1) and an OLC45 steel layer (2); b. a duraluminium layer (3), a ceramic layer (4) and a HEA layer (1); c. a HEA layer (1), a first duraluminium layer (3), a second HEA layer (1), a DYNEEMA polymer layer (6) and a second duraluminium layer (3). According to the invention, the process for carrying out the structure consists in making the structure with two layers by plating them by explosion or brazing with brass, while a second and a third structure made of three and five layers, respectively, are carried out by attaching the layers to one another with an adhesive (5).
