The CNR used in the present investigation was synthesized using recycled materials (potato peel) and hydrothermal methods. The impact of CNR on the vibrations is analyzed using numerical and experimental evidence. Experimental results show that by adding 0.32 % CNRs, the natural frequency increases by 46.6 %. The equations are formulated based on the sinusoidal shear deformation beam theory and the neutral axis. Then, the equations are solved using the Ritz method. The study examines the impact of different parameters, including rotational speeds, axial force, Young's modulus of the resin epoxy and glass fibers, aspect ratio, temperature change, volume fraction of CNR, and thickness on Campbell diagrams for the composite beam with and without CNR as reinforcement. Gyroscopic effects of the composite beam caused by the rotation of this beam around the y and x-axis are investigated. The Campbell diagrams, which are based on the rotational speed of the thick structure, reveal that higher temperatures lead to a decrease in natural frequency. Conversely, raising Young's modulus increases the natural frequency because increasing the stiffness of composite beam. By enhancing volume fraction of CNR, the damped and undamped natural frequency increases. Augmenting the velocity of the structure diminishes the natural frequency. The angular velocity along the y-axis exerts a more significant impact. The traction force significantly enhances the natural frequency of the rotating structure. The findings indicate that CNR is an economical and eco-friendly substitute for nanotubes. This amplifier is used in several sectors, including aviation, terrestrial, and maritime transportation, as well as in rotating turbines, rotating structures, and rotary drilling machinery. Also, the comparison of different theories shows that the effect of SSDT on the natural frequency is lower than that of the other theories.</div></div>","PeriodicalId":52306,"journal":{"name":"International Journal of Lightweight Materials and Manufacture","volume":"8 5","pages":"Pages 669-680"},"PeriodicalIF":0.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144654023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional fusion welding of aluminum often leads to significant defects such as porosity and distortion. Friction Stir Welding (FSW), a solid-state welding technique, addresses many of these challenges but has limitations when welding thick plates, which can be alleviated through the use of a bobbin tool. This study presents a comparative analysis of a novel one-step double-acting tool, which operates dual tools simultaneously on both surfaces of the workpiece, against the bobbin tool. Aluminum AA1100 sheets measuring 200 × 240 mm and 8 mm thick were welded using both methods under standardized parameters: a tool rotation speed of 1500 rpm, a plunge depth of 0.2 mm, a travel speed of 25 mm/min, and a tilt angle of 2°. By varying the offset of the one-step double-acting tool between 0 mm and 2 mm, the impact on bead appearance and mechanical properties was assessed. Results indicated that the bobbin tool produced rougher beads and tear defects due to its design, while the one-step double-acting tool, particularly at a 2 mm offset, yielded cleaner, more uniform welds with fewer defects and enhanced material control. Microstructural analysis showed that the stir zone exhibited uniform grain refinement, and the Heat-Affected Zone (HAZ) benefited from finer grain structures due to improved heat management. Hardness testing revealed a characteristic W-shaped distribution, and tensile strength evaluations demonstrated the superior joint quality of the 2 mm offset, outperforming the bobbin tool in tensile strength and defect reduction. Although the bobbin tool showed slightly higher average strength in bending tests, the one-step double-acting tool proved to be more consistent and reliable.</div></div>","PeriodicalId":52306,"journal":{"name":"International Journal of Lightweight Materials and Manufacture","volume":"8 5","pages":"Pages 577-594"},"PeriodicalIF":0.0,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144654017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In turn, insufficient inert wetting due to the short contact time of the melt during the LPBF process leads to the formation of gaps at the Al/AlN interphase boundary.

Most plastic waste generated worldwide is mismanaged, leading to plastic pollution, landfill congestion, and microplastic contamination. Circular economy practices in the sustainable production and consumption of plastic are urgently needed to address these challenges, bringing plastics into closed-loop manufacturing and utilization. Additive manufacturing (AM) or 3D printing (3DP) have the potential to complement these efforts by facilitating on-demand, decentralized and flexible manufacturing using recycled plastics. In pursuit of circular materials for 3DP, this study investigates the influence of infill design and density on tensile and dynamic mechanical properties of 3D-printed recycled polyethylene terephthalate (rPET) sandwich structures. rPET filaments were produced using waste plastic bottles and were used for the 3DP process to produce sandwich structure coupons. In the first phase, the rPET filaments were tested for their mechanical properties revealing an average tensile strength of 111.99 MPa, failure strain of 1.20, and Young's modulus of 199.61 MPa, followed by the 3DP of tensile testing coupons with varying infill patterns (grid, tri-hexagon, octet, concentric, gyroid, and solid) and infill densities (25%, 50%, and 75%). The 3D-printed sandwich structures were evaluated for their dimensional stability and mechanical properties. All patterns demonstrated good dimensional stability, with minor variations from the CAD model. The mechanical properties of the concentric pattern at 50% infill (C50) stand out as the best among all infill types and patterns, exhibiting an average tensile strength of 34.65 MPa, failure strain of 0.067, Young's modulus of 464.32 MPa, and strength-to-weight ratio of 8.56 (S/W). In the final phase, the optimal infill pattern and density (i.e., C50) were also tested for their dynamic mechanical properties.
