Inspired by the biological ability of animals to perceive vibrations through their limbs, the integration of sensors into robotic legs significantly enhances environmental perception capabilities. However, the design of such sensors involves considerable technical challenges due to the limited space and uneven surfaces of robotic legs, necessitating miniaturization, flexibility, durability, and a wide frequency response range. Addressing these challenges, this study presents a flexible accelerometer integrated into robotic legs for effective vibration sensing in complex environments. The proposed ultra-thin grid-like sensor (UGS), with a thickness of only 0.5 mm, is based on triboelectric nanogenerator principles. It is fabricated using copper and polytetrafluoroethylene powders with optimized particle size combinations, enhancing the contact area and improving output performance. The UGS demonstrates exceptional flexibility, a broad frequency detection range (8 Hz–6 kHz), high sensitivity (0.49584 mV/(m/s²)), and remarkable durability, maintaining performance over 35,000 cycles. It effectively detects environmental vibrations as well as signals generated by the robot's movements. Coupled with a time difference of arrival-based localization algorithm, the sensor supports multi-scenario vibration source localization experiments in environments, achieving average angular and distance accuracies of 97.72 % and 95.26 %, respectively. This study highlights the potential applications of the UGS in pipeline leakage detection, machinery fault diagnosis, and structural vibration monitoring, offering innovative solutions for robotic environmental sensing.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"305 ","pages":"Article 112710"},"PeriodicalIF":12.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144314317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CFRTP/AA5052 aluminum (5052) FLSW hybrid structures achieve a tensile shear strength of 126.75 N/mm, surpassing the spontaneous fracture joints manufactured by traditional friction lap welding.

Systematic experimental and density functional theory (DFT) analyses indicate the dual covalent bonding pathways of Zn–O and Al–O covalent bonds formed within the FLSW hybrid structures. Higher Al doping content in α-Zn enhances mechanical properties, lower anisotropy, and stronger covalent bonds. The Zn–Al eutectic layer exposes both Zn and Al atoms for covalent bonding with oxygenated groups of CFRTP, whereas traditional hybrid joints relied solely on sparse Al–O bonds from surface oxides.

Traditional energy-absorbing materials, such as honeycombs and random foams, have limited potential for optimizing energy absorption. Recent advances in additive manufacturing (AM) have enabled high-performance energy-absorbing structures with rationally designed architectures; however, many of these impact-resistant designs still lack tunable energy absorption for a wide range of applications. Inspired by the fractal patterns of Greek key, a group of lightweight architected materials with expanded mechanical performances, which are easy to manufacture and popularize, were designed to address this challenge. By adjusting the fractal order, cell wall thickness, cell wall gradient, and biaxial pre-strain, out-of-plane mechanical performances, including stiffness, strength, and energy absorption were significantly expanded. Increasing the fractal order resulted in an 85 % increase in energy absorption compared to baseline honeycomb structures. The introduction of wall thickness gradients enhanced energy absorption by up to 522 % compared to the no-gradient case and 331 % more at higher strain levels than honeycombs. Moreover, applying a 20 % biaxial pre-strain increased energy absorption by 45 %. The enhanced mechanical performance originates from the constrained buckling and internal friction mechanisms occurring among the post-buckled cell walls. These findings could pave the way for the development of advanced metamaterials with superior energy absorption capabilities, making them highly adaptable and efficient for a broad range of impact scenarios, including aerospace applications, automotive safety systems, and personal protective equipment.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"305 ","pages":"Article 112711"},"PeriodicalIF":12.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144255420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we propose an orthogonal design for all-inorganic nanocomposite using innovative composite molding techniques. The increased path tortuosity is tailored during the electrical treeing process through the orthogonal distribution of ferroelectric nanofillers, ensuring the preservation of high breakdown strength and polarization. Meanwhile, a gradient-sandwich multilayer configuration is developed to leverage the interfacial polarization effect and interface barrier effect between adjacent layers. Hence, integrating a gradient electric field distribution enhances both the polarization and breakdown strength of the nanocomposites, ultimately resulting in a significant improvement in energy storage performance. The ultrahigh energy density of 24.5 J cm⁻³ at a low electric field of 1700 kV cm⁻¹ is obtained in orthogonal orientation gradient-sandwich structure ≈1.8 times that of the parallel filler orientations nanocomposites.

However, the effectiveness of ML models are often constrained by limited datasets, due to the high cost and time required for experimental data acquisition. To address this, this paper presents the first study to apply virtual sample generation (VSG) techniques to enlarge the training dataset and mitigate data scarcity in the prediction of CFRP drilling performance. A novel hybrid ML framework integrating Broad Learning System (BLS) and VSG (BLS-VSG) is proposed to combine the capability of BLS in small dataset prediction with the enlarged dataset generated by VSG. The model has been employed to predict the drilling thrust force and delamination damage under various drilling conditions (spindle speed, feed rate, point angle). Three different VSG methods (SMOTE, MD-MTD and CVT) and the number of virtual samples were evaluated in detail. Results show that VSG can effectively enlarge the training dataset and improve the prediction performance of the ML model. Specifically, VSG reduced the mean square error (MSE) and mean absolute percentage error (MAPE) for thrust force prediction by 39.0 % and 12.9 %, respectively, compared to the benchmark without VSG. For delamination factor F_da prediction, MSE and MAPE were reduced by 22.6 % and 16.5 %, respectively.

Therefore, this study proposes a novel self-similar fractal strategy of CFRP/stainless steel nested structure to fully exploit the mechanical advantages of distinct materials. The structure consists of an outer quadrilateral CFRP tube nested with an internal stainless-steel fractal substructure, named the Quadrilateral Fractal Nested Structure (QFNS). Through the compression test, it is found that the CFRP/stainless steel nested structure has more stable mechanical loading behavior compared with the pure metal structure. Numerical simulations further explored the energy contribution mechanism, which reveals that the load-bearing capacity of QFNS surpasses the combined performance of its individual components, emphasizing the significant interaction effect between internal and external structures. In addition, the fractal order, the number of paving layers and the fractal wall thickness significantly affect its crashworthiness. In particular, when the fractal order increases from 0 to 2, the specific absorption energy increases (SEA) by 122.97 %.

Three-dimensional Hashin damage criterion was implemented to predict the progressive failure of PGFRP materials in an accurate and repeatable manner.
