The purpose of the research is to create the scientific foundations of effective technological methods for the manufacture of rocket-space, aviation and defense equipment products and modern materials with high characteristics based on the determined laws of the formation of material properties and interdependencies of technological parameters and quality indicators. Research methods: mathematical and physical modeling; practical field experiments; X-ray structural and micro structural studies; metallographic analysis. The work contains a justification of the priority scientific direction of the influence of physical fields on the processes of forming structures from structural plastics. The peculiarities of the influence of technological, structural and material science factors have been revealed. A solution to the strengthening of epoxy plastics due to the influence of infrared radiation and magnetic fields at various stages of the technological process is proposed. The values of technological parameters for obtaining water-sprayed aluminum powders are determined. There is no continuous crystalline oxide film on the surface of the particles. Was worked out an algorithm for the development of a technological scheme of production the aluminum powders and products from them. Established quality characteristics of aluminum powders, suitable for the production of large-sized work pieces. Developed the classification of structural elements of technical systems, which could be manufacture of powder aluminum alloys. A new method of modeling a high-speed electric drive used in injection systems has been created. The advantages of the method are achieved due to the use of physical Cauer circuits in the simulation of transients in massive ferromagnetic parts of the drive.
