Composite face sheets were attached to the top and bottom surfaces using a film adhesive to create sandwich structures, which were subsequently machined to appropriate sizes for compression and impact testing. Comparative analysis with conventional meta-aramid paper and aluminum core specimens showed that the CF composite honeycomb core demonstrated superior performance in terms of compression modulus, compressive strength, and strength-to-weight ratio.

The accuracy, uniformity, and repeatability of the nanoparticle impregnation process determine the quality of the functionalities bestowed on such flexible hybrid composites. Current evaluation techniques like various types of spectroscopy or microscopy are either resource-intensive or are practical only for very small sample sizes. Therefore, there is a critical need for a fast, full-field, cost-effective, non-destructive and reliable technique to evaluate the impregnation quality for woven fabrics. To this end, the development of a new approach using digital image analytics (DIA) to evaluate the uniformity and accuracy of nanoparticle impregnation in woven fabrics is explored in this study. In this study, the impregnation of 80 nm spherical silica nanoparticles into Kevlar 29 style 745 fabric is considered as the test case for all treatment levels. Three trackable heuristic markers are identified from grayscale value histograms of digital images to extract statistically-relevant data sets for neat and treated samples that enable correlation with nanoparticle impregnation. Heuristic feature shifts in grayscale value histograms and spatial frequency profiling correlate with different treatment levels, serving as quantitative metrics to assess uniformity and accuracy of nanoparticle impregnation in the fabric. Further, scanning electron microscopy and energy dispersive X-ray spectroscopy are used to validate the predictions from DIA, thus demonstrating its capability to act as a powerful new tool to evaluate hybrid materials that are seeing greater use in modern technologies.</p>\u0000 </div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"33 2","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147561934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a quasi-static finite element sequential interaction modeling framework to investigate electro-mechanical phenomena at the microscale in SSCs. By explicitly excluding the Electric Double Layer (EDL) physics, the model focuses on how compressive stress influences the bulk electrostatic field distribution within a representative fiber-electrolyte architecture. This approach serves as a geometric benchmark to isolate first-order effects. Results reveal a deformation-induced evolution of electric field distribution, particularly near fiber-separator line interfaces, which in turn affects the local charge storage behavior. Although the overall capacitance is largely retained under compressive deformation, minor variations arise due to small changes in fiber proximity and the mechanism termed Geometric Electrostatic Screening. Parametric studies demonstrate that fiber volume fraction and spatial arrangement play a significant role in the capacitance, with optimized geometries enabling up to 20% improvement in charge storage. Furthermore, extending electrode length in the fiber-aligned direction enhances capacitance more effectively than increasing thickness due to electrostatic screening effects. This framework provides insights into the interplay between structural geometry and electrostatic performance, serving as a basis for the design of high-performance multifunctional composites.</p>\u0000 </div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"33 2","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10443-026-10452-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147561633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hugoniot equations of state and spall strength, concerning high-pressure shock compression and high-strain-rate tension, are derived from free-surface velocity measurements. Spall strength of the PEEK-CF composite exceeds that of PEEK-GF due to its larger fiber length and stronger interfacial bonding; the fiber-matrix interfaces in the composites give rise to their reduced spall strength compared to pure PEEK. As impact velocity increases, spall strength for both the composites first increases and subsequently decreases due to the competing effects of shock-induced heating and strain-rate hardening.
