However, current challenges stem from the coupled limitations of polarization and breakdown field strength in dielectric capacitors, which present significant obstacles to achieving a breakthrough in energy storage performance. 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. Incorporating the orthogonal orientation and gradient-sandwich structure strategy significantly enhances energy output, making it suitable for a wide range of electronic devices.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"305 ","pages":"Article 112673"},"PeriodicalIF":12.7,"publicationDate":"2025-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144279934","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}

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. The proposed BLS-VSG model outperforms other conventional ML models (BPNN, ELM, SVR and RT) for both scenarios (with/without VSG), providing a robust and data-efficient solution for CFRP drilling performance prediction.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"305 ","pages":"Article 112701"},"PeriodicalIF":12.7,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144314318","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}

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 %. Moreover, compared to typical CFRP/metal structures, the self-similar fractal design elevates SEA by 110.39 %.

The objective of this study is to investigate the effect of non-uniform RMC architecture on the performance of PGFRP members subject to flexure, focusing on the failure mode characterized by cracking at the flange-web junctions of such members. This study considers five PGFRP shapes – box, I, C, T and L – and quantifies non-unform RMC architecture for 18 sections. A robust FE model capturing the individual roving and CSM layers of the PGFRP was developed, and both non-uniform and idealized uniform RMC architectures were modeled in every case allowing the effect of RMC architecture variation to be investigated. Three-dimensional Hashin damage criterion was implemented to predict the progressive failure of PGFRP materials in an accurate and repeatable manner. A parametric study varying fiber volume ratio, CSM proportion and shear span resulted in 360 separate FE models.

This review paper provides an in-depth and comprehensive overview of some important advances in structural design to obtain novel bio-inspired structures with improved energy absorption properties. The structural designs are categorized and summarized based on the common characteristics of biomimetic structures and their bio-inspired sources, and detailedly introduced in terms of the structural configurations, manufacturing processes, analysis methods and energy absorption properties as well as the comparative analysis of performance indicators. Moreover, the application investigations of biomimetic lightweight structures across diverse engineering domains are explored. The introduction of biomimetic structural characteristics indeed significantly improved the structural energy absorption performance and crashworthiness while maintaining the similar overall weight. This phenomenon drives many researchers to devote themselves to this investigations, and continuously achieve new research results. Meanwhile, the endless variety of biological species in nature provides inexhaustible sources for biomimetic structural designs. However, most of these investigations stop at laboratory and are difficult to achieve actual applications due to their various limitations such as manufacturing processes, serviceability in specific environments, the cost of innovative materials and production, product maturity, and the feasibility and cost of mass production.
