“…An aliphatic polyurethane plastic with a low viscosity was chosen as a model material. The density of the model material is 1.07 g/cm 3 , the tensile strength is 21.8 MPa, and the hardness is 72 HSD. Polyurethanes are the most valuable and widely produced polymers in the industry.…”

“…Super-deep penetration (SDP) is a complex physical phenomenon, when in a split-second flow of powder particles with a fraction less than 100 microns, accelerated to speeds of 700-3000 ms -1 , penetrates the solid metal body at depth in tens, hundreds mm. Simultaneously, the high and ultra-high pressure (0.2-20 GPa), intensive deformation, local heating, and friction is occurred [3][4][5]12].…”

The problem of protecting spacecraft from cosmic dust has recently come to the fore. There is still no enough data on the complex effect of short-term high-energy, dynamic loading on materials, including polymer materials and multilayer polymer-metal composites. The use of dynamic alloying in the super-deep penetration (SDP) mode by high-speed flows of powder particles allows assessing the effect on the material under dynamic action. Previous studies on steel and aluminum samples have shown a significant effect of high-speed flows of powder particles on the structure and properties of materials. As a result of a study of samples made of aliphatic polyurethane with steel reinforcement elements, it was found that there are traces of the penetration of high-speed particles into both metal and polymer layers. However, the number of flow elements detected in the polymeric part is significantly less than the number of elements in the metal reinforcing part. Thus, it is possible to assume that or the polymer material is a more effective barrier to the high-speed flow compared to the metal, or the “self-healing” effect is observed.

The dynamic effects observed in collisions represent a specific area of high-energy interaction located at the boundary of mechanics, hydrodynamics, shock wave physics, and alternating high-pressure regions. The paper shows that in the volume of a solid metal body, as a result of dynamic alloying by a high-speed stream of powder particles in the super-deep penetration mode (SDP), fiber structures of altering material arise, forming the framework of the composite material. The stream of powder particles in the metal obstacle following the path of least resistance and the impact of shock waves on particles results in a volumetric framework from the products of interaction between the injected and matrix materials. When using SDP, defective structural elements (channeled)—germs of reinforcing fibers arise. At the subsequent heat treatment, there is an intensive diffusion. The growth process of reinforcing fibers shifts to higher temperatures (as compared to the standard mode), leading to an increase in the bending strength of the fiber material up to 13 times for W6Mo5Cr4V2 high-speed tool steel. As a result of the completion of the growth of reinforcing fibers in the volume of the W6Mo5Cr4V2 high-speed tool steel, the material’s bending strength in 1.2 times is realized. Simultaneously, it provides an increase of wear resistance 1.7–1.8 times.

“…The specificity of this treatment is an achievement of impulse of high pressure in the range of very short intervals. During SDP process powder particles work as needles and the fibers are formed in metal matrix under dynamic interaction between powder particles and matrix material [5]- [6]. Dynamic loading of surfaces by powder streams may ensure the intensification of subsequent nitriding and increase the wear resistance of the resulting layer.…”
