Tool material selection methodology for aircraft elements design

The technology and technological equipment selection have to be substantiating for the modern materials for product the aircraft construction elements from polymer composition. The physical and technical characteristics of the material, ensuring the required accuracy of manufacturing equipment, as well as economic feasibility are the main criteria for choosing the material of technological equipment. The material equipment choosing is depends on the polymer composite construction technology manufacturing. The methodic of rigging materials selection for aircraft constriction elements production from polymer composition by vacuum infusion is considered in that paper. The results of a comparative analysis of typical materials equipment used in production are presented are considered in that paper. It is shown that the main criteria for a comparative analysis are: temperature, resistance to solvents, resistance to mechanical stress; maintainability; the value of the coefficient of linear thermal expansion; the stability of the geometry of the equipment and its tightness. It was showing that the metals and carbon fiber composite are the most appropriate for equipment manufacture that used in high temperature processes manufacturing composite components. The materials equipment algorithm choosing for polymer composite components manufacturing is considered in that paper. It is noted that the same material have to be choosing for equipment manufacturing as the carbon fiber or fiberglass polymer composite component. This allows to ensure the same CLTE, which is important in hot forming of the composite component, and to eliminate warping of the composite component during its cooling on the equipment. However, the equipment gelcoat processing has to be taking into account for specified accuracy achievement. The quantitative assessment of the economic feasibility of material equipment choosing is considered in that paper. It is shown that only a combination of technical, technological and economic factors makes it possible to substantiate the expediency of the rigging material used for the specific production of aircraft construction elements.
