“…Next, a metal cylinder with the butt area of 1 cm 2 was fixed to the test object using cyanoacrylate glue "Moment" ("Henkel"), which was attached to the upper clamp of an Instron 3382 tensile testing machine by means of a flexible rod. The values of the tensile strength were recorded using the StretchTest program [16]. To determine the peel strength σ, test objects in the form of disks with an area of 1 cm 2 were made from PLA filament on the surface of a PET substrate (Figure 3).…”

“…Polyethylene-terephthalate-glycol (PETG) [13], polylactide (PLA) [14], and the acrylonitrilebutadiene-styrene copolymer (ABS) [15] seem to be useable for the creation of semiconductors and conductive polymer-based elements with extrusion 3D printing. However, the low interlayer adhesion of the filament and the peeling of the formed prototypes from the heated 3D printer platform can lead to critical product defects [16]. Moreover, typical filaments do not always and fully satisfy the technological requirements of the original components when used in repair processes (for example, due to the differences between the physics-chemical characteristics of metals and polymers).…”

A new technique of additive prototyping filament volumetric nanostructuring based on the high-speed mechanical mixing of acrylonitrile-butadiene-styrene (ABS) copolymer granules and single-walled carbon nanotube (CNT) powder (without prior dispersion in solvents) is considered. The morphological spectra of scanning electron microscopy (SEM) images of nanostructured filament slice surfaces were obtained and characterized with the original mathematical simulation. The relations of structural changes in the “ingredient-matrix” polymer system with dielectric and mechanical properties of the ABS-based filaments were established. The supplementation of 1.5 mass.% of CNT powder to the ABS filament composition leads to the tensile strength increasing from 36 ± 2 to 42 ± 2 MPa. It is shown that the greater the average biharmonic amplitude and the morphological spectrum localization radius of the slice surfaces’ SEM images, the lower the electrical resistance of the corresponding nanostructured filaments. The possibility of carbon nanotube-modified filament functional layers forming using the extrusion additive prototyping technique (FFF) on the surface of plasma-chemically modified PET substrates (for the creation of load cell elements) is experimentally demonstrated.

“…Таким образом, выбирая способ и режим модификации поверхности, адгезионными, лиофильными, трибологическими и многими другими свойствами полимерных материалов можно управлять эффективно [56][57][58]. В частности, микротекстурирование изготовленных методом аддитивного прототипирования макроскопических экспериментальных образцов может осуществляться за счёт сочетания механических напряжений (при деформации гибкой полимерной подложки в различных направлениях с разными удельными механическими усилиями [59]) с последующей поверхностной модификацией [60] полимерного материала фтор-и кислородсодержащими газовыми смесями [61][62][63].…”

The work is devoted to the use of methods of applied mathematics and statistics for the formalization and mathematical modeling of the structure of shark skin as a prototype of new polymer materials for shipbuilding purposes. A technique for mathematical modeling of biological objects is described, and a method for using a biomimetic approach for the design of planar composite polymer materials with improved lyophilic adhesion properties is proposed. Because of studying images of shark skin obtained using high-resolution optical (HRO) and scanning electron (SEM) microscopy, we found that its texture is anisotropic. Quantitative analysis of BOM and SEM images made it possible to rationalize the choice of synthetic digital models intended for simulation prototyping of maximally and minimally texturally isotropic polymer samples using 3D printing and gas-phase surface modification.
