Technological Heredity during the Production and Operation of Structural Materials

Development of Construction and Repair Materials Used in Transport and Technological Machines Operating in the Arctic

“…For this purpose, we introduce restrictions on the vector space of objective functions and represent them in the form of expressions (8): (max) . (8) As additional restrictions when solving a multicriteria optimization problem, the following can be taken: the mass of a PCM structure with a given location scheme for viscoelastic components in the matrix m(x* 1 , x* 2 , ..., x* n , f* 1 , ..., f* )≤m per , where m per is the permissible mass of a composite structure; the cost of manufacturing the structure С(x* 1 , x* 2 , ..., x* n , f* 1 , ..., f* m )≤С per , where С per is the permissible cost price of manufacturing a structure from a composite with a given location scheme for viscoelastic components in the matrix; LI(x* 1 , x* 2 , ..., x* n , f* 1 , ..., f* m )≤ LI per labor intensity of manufacturing a structure from PCM with various types of hybrid matrices, where LI per is the permissible labor intensity of manufacturing a structure from PCM with a given scheme for the location of viscoelastic components in the matrix.…”

“…Among the modern methods of repairing machine parts, polymer technologies have recently been widely used [8]. This is due to the low labor intensity and cost of repair work, as well as the lack of the need to attract qualified specialists.…”

Influence of Polymer Matrix Chemical Nature and Molding Technology on the Quality of Carbon Fiber Reinforced Polymer Parts

“…The primary quality markers for metal parts are machining accuracy and surface roughness. The analogy for polymer composite material (PCM) details is porosity [1,2]. The reason is in an impossibility of machining composites due to low interlayer shear strength therefore the delamination when processing can occur [3,4].…”

Research of Kinetic Impregnation Process Based on the Structure of Reinforcing Filler

“…Composite Materials are becoming more popular gradually replacing traditional materials with extra strength, lighter weight, and thermal properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Many composites' industries are exploring the use of fiber-reinforced composites in all applications which includes aerospace, automotive and water transport, construction industry, toys, instrumentation, medicine, etc.…”
