“…Поскольку дисперсноупроченные композиционные сплавы являются гетерофазными системами с развитой сетью межфазных границ, их изготовление сопровождается активным протеканием таких процессов, как химические реакции и взаимная диффузия между матричным расплавом и наполнителем. Для получения качественных АКМ необходимо ограничивать это взаимодействие, исключая деградацию упрочняющей фазы, приводящую к снижению механических и эксплуатационных свойств литых деталей [10,11].…”

The possibilities of obtaining aluminum matrix composite materials of the composition Al−Al2O3 are considered by the method of liquid-phase oxidation of aluminum by purging the melt with oxygen. The obtained materials are a two-phase system with different concentrations of the solid phase. An algorithm for calculating the kinetics of aluminum oxidation in obtaining the oxide phase of an aluminum matrix composite is proposed. It is established that the beginning and completeness of the reaction on the surface of the gas bubble determines the synthesis of the oxide phase and is determined by the functions T(t), h(t) in the region of dynamic time delay, which, in turn, the queue is revealed as a function of the temperature in the contact zone of the gas bubble with the melt, taking into account the duration of the heating of the bubble along the cross section and the radius of the bubble itself. The microstructures of the obtained materials with different structural-phase state with variations in the time of purging and oxygen supply to the aluminum melt are presented

“…Since dispersion-hardened composite alloys are heterophase systems with developed network of interphase boundaries, their manufacture is accompanied by actively running processes such as chemical reactions and interdiffusion between the matrix melt and the filler. Production of high-quality AMCs requires this interaction to be restricted, to exclude the strengthening phase degradation resulting in reduction of mechanical and operating properties of cast parts [10,11].…”

“…Restrictions are also imposed by the methods of manufacturing parts. The development of additive technologies [6], in particular from polymer composite materials [7][8], makes it possible to manufacture products that were previously inaccessible [9]. Such structures include bioinspired structural arrangement based on natural analogs -the direction of installation, shape, quantity, orientation in space of power elements is similar to biological analogous objects, for example, insect wings [10].…”

Aircraft frame elements are highly responsible elements. They are subject to stringent requirements for strength, stability, resource. Often these requirements contradict each other, especially if it is necessary to ensure the minimum mass of the product. However, it is necessary to improve the characteristics of aircraft. Nevertheless, the optimization of the frame has almost exhausted itself. The power frame consists of longitudinal and transverse elements. It is possible to improve the characteristics of structural arrangement by using polymer composite materials based on glass and carbon fibers. This will improve the design characteristics due to high specific properties. In addition, one of the directions is the development of new bioinspired structural layout based on natural analogues. The work is devoted to the actual task of searching and choosing new structural arrangement for the aircraft tail. The paper considers five variants of structural layout, including the classical original design. The advantage of the bioinspired variant in terms of mass and displacement is shown.
