It is known that the use of these dissimilar polymers enables the formation of the samples with high interlaminar shear strengths. Despite the difference in their elastic moduli and glass transition temperatures, similar melting points (266 °C for PEI and 262 °C for PES) ensure the formation of uniform structures at the interfaces with negligible discontinuities when using the prepregs reinforced with the CF fabric. In the laminates with the CF veil and the PES technological layer, some discontinuities at the interfaces are caused by the differences in the physical, mechanical, and thermal properties of the joined components. PES has a lower elastic modulus than PEI, so its frictional heat generation is decreased. On the other hand, PEI is the first to melt during US–consolidation due to its lower glass transition temperature (194 °C versus 227 °C for PES). At the same time, the irregular reinforcement of the laminates with the CF veil does not prevent the polymers from their intensive mixing, contributing to the formation of pores and reducing their mechanical properties.</p></div>","PeriodicalId":770,"journal":{"name":"Russian Physics Journal","volume":"69 2","pages":"218 - 226"},"PeriodicalIF":0.8,"publicationDate":"2026-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148699661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanical behavior of these composites strongly depends on the reinforcement fractions and powder metallurgy processing parameters, making accurate property prediction a nonlinear and multivariable challenge. In this study, a comparative machine-learning framework is developed to predict the tensile strength and hardness of aluminum–Silicon Carbide (SiC) composites fabricated within defined processing conditions. Experimental data were generated for the SiC contents of 0–9 wt.%, compaction pressures of 400–800 MPa, sintering temperatures of 350–580 °C, and sintering times of 90–145 min. An Artificial Neural Network (ANN) was optimized using Genetic Algorithm (GA) and Bayesian Optimization (BO) for hyperparameter tuning. The GA-optimized ANN demonstrated superior predictive performance (<i>R</i><sup>2</sup> = 0.9710 and <i>RMSE</i> = 5.93 MPa) compared to the BO-optimized model (<i>R</i><sup>2</sup> = 0.9543 and <i>RMSE</i> = 7.40 MPa). Our residual analysis confirmed improved stability and reduced systematic bias for the GA. The SHapley Additive exPlanations (SHAP) technique revealed that compaction pressure, SiC fraction, and sintering temperature dominate mechanical response, consistent with densification and diffusion-driven strengthening mechanisms. The developed framework provides a robust predictive tool valid within the investigated processing domain.</p></div>","PeriodicalId":770,"journal":{"name":"Russian Physics Journal","volume":"69 2","pages":"199 - 209"},"PeriodicalIF":0.8,"publicationDate":"2026-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148699658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensing principle is based on the periodic microbending-induced optical losses resulting from mechanical deformation of a multimode optical fiber, which modifies the evanescent field and enhances the coupling to radiation modes. Three microbend cells with different pitches (3, 5, and 8 mm) are fabricated using locally manufactured periodic mechanical curvatures. The experimental setup consists of a multimode optical fiber, an 810 nm laser diode source, a microbend deforming cell, and an optical power meter. The external forces in the range of 5–60 N are applied to induce strain in the fiber, and the corresponding strain values are calculated for each microbend configuration. The results indicate that the 3 mm microbend cell exhibits the highest strain sensitivity, with a maximum strain of ε = 7⋅10<sup>−8</sup> at 60 N and a minimum strain of ε = 1⋅10<sup>−8</sup> at 5 N. For the 5 mm cell, the strain ranges from ε = 2⋅10<sup>−9</sup> at 5 N to ε = 1.3⋅10<sup>−8</sup> at 60 N. In contrast, the 8 mm cell exhibits the lowest strain response, with the strain values ranging from ε = 1.5⋅10<sup>−10</sup> at 5 N to ε = 4.5⋅10<sup>−10</sup> at 60 N. The calculated sensor sensitivity is approximately 0.02 per unit force, demonstrating the suitability of the proposed microbend sensor for practical structural strain monitoring applications.</p></div>","PeriodicalId":770,"journal":{"name":"Russian Physics Journal","volume":"69 2","pages":"251 - 259"},"PeriodicalIF":0.8,"publicationDate":"2026-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148699633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

UV–Vis spectroscopy revealed a progressive blue shift of the surface plasmon resonance peak from ~450 nm at a low flow to ~420 nm at a high flow, accompanied by a narrowing of the FWHM, indicating to the particle size reduction and improved dispersion. X‑ray diffraction patterns confirmed the formation of face-centered cubic Ag with the decreasing crystallite size with the increasing flow, as calculated from the Scherrer equation. SEM images demonstrated that higher flow rates produced smaller and more uniform spherical nanoparticles, whereas the lower flow resulted in agglomerated clusters. The FTIR analysis identified hydroxyl, nitrate, and organic groups associated with the nanoparticle surface with diminished intensities at higher flows, reflecting an improved reduction and stabilization of metallic Ag.
