On the possibility of improving operational characteristics of materials by preliminary pulse or impact treatment

Effect of Explosive Processing on the Structure and Properties of Polyarylate

“…The use of antifriction materials made from heat-resistant polymers provides not only high physicomechanical, tribotechnical characteristics, but also expands the temperature limits of the operability of machine parts [1]. For the manufacture of parts of friction units operating under severe temperature conditions and in corrosive environments, it is effective to use aromatic polyester (polyarylate PA, polyoxybenzoyl) that has high thermal conductivity (3)(4)(5) times greater than most other polymers), dielectric strength, stiffness and wear resistance, thermal and chemical resistance, good creep resistance, low coefficient of thermal expansion [2][3][4]. However, the brittleness of the polymer, high temperatures (400-420 °С) and pressure (100-150 MPa) during the molding of products require new efficient methods for its processing [3][4].…”

“…However, the brittleness of the polymer, high temperatures (400-420 °С) and pressure (100-150 MPa) during the molding of products require new efficient methods for its processing [3][4]. To achieve a new level of product properties, it is possible to use various technological methods for activating hard-toprocess polymers (chemical modification, radiation, ultraviolet and other high-energy effects) [5][6][7][8][9][10]. A promising way of obtaining products from powders of hard-to-process polymers is explosive processing (EP) [10][11][12][13][14].…”

The Effect of Explosive Treatment on the Structure and Thermomechanical Properties of Filled Polytetrafluoroethylene

“…The level of the service properties of composites is ensured primarily by the intensity of adhesion interaction of components, increase in which is possible by using mechanical, chemical (treatment with surface-active substances), or high-energy treatment (shock treatment, radiation exposure, ultraviolet, ionising, laser, and ultrasonic irradiation, etc.) [3–11]. A promising method for producing filled polymer composites (PCMs) is explosive treatment (ET), which makes it possible to combine processes of activation and pressing of powder composite mixtures.…”

Deforming of Elastic-Plastic Medium with Self-Similar Restriction

“…Kovtanyuk [7][8][9]. Using this model, in [10][11][12][13][14][15] the boundary value problems were solved. In the work [16] this model was used to describe influence of irreversible strains on propagation of elastic waves.…”
