Laminates were fabricated via the open mould technique, and material properties were obtained through uniaxial tensile testing per the ISO 527–5 standard. Experimental modal analysis (EMA) and finite-element simulations in ABAQUS using S58R shell elements with engineering constants showed strong agreement. The ANN was trained on experimental and numerical data to predict the natural frequencies under varying laminate sequences, aspect ratios, and thickness ratios. The obtained results indicate that increasing the aspect ratio, side-to-thickness ratio, and fibre orientation angle reduces the natural frequencies of FML. The first mode of natural frequency increased by 83.80%, 84.85%, and 89.52% for CFCF, CCCF, and CCCC boundary conditions, respectively, compared to CFFF. Conversely, increasing fibre angles led to reductions in the natural frequency of 1.662–7.385% for CFFF, 0.027–1.146% for CFCF, 0.175–0.705% for CCCF, and 0.036–0.148% for CCCC. The ANN model demonstrated high accuracy and efficiency, supporting its use in the design and optimization of advanced composite structures. </p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"26 8","pages":"3551 - 3571"},"PeriodicalIF":2.3,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145145585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the inherent brittleness of glass fibres often results in fibre blow-out through exhaust ducts, exacerbated by vibration and air pressure. Encapsulating the glass nonwoven between continuous filament-based knitted fabrics effectively controls fibre blow-out, enhancing the durability and reliability of the acoustic insulation. The structure of knitted fabrics and the selection of roving substantially influence the thermal and acoustic performance of sandwich-absorbing materials. To investigate the effects of these structural parameters, a full factorial design experiment (DOE) was conducted. This DOE incorporated roving linear density (ranging from 200 to 600 Tex) and knit stitch length (8–12 mm) as continuous variables, along with roving type (flat and texturized) as a categorical variable. The structure of texturized roving was characterised using optical imaging. Rib-knitted fabrics were developed based on the DOE, and their structural characteristics, such as total porosity, straight porosity, and straight pore radius, were analysed through optical microscopy image processing. The sound absorption properties and flow resistivity of the knitted specimens were evaluated. Additionally, high-temperature contact heat transmission and sound absorption behaviour of the sandwich structure were assessed. A significant relationship between the structural parameters of the knitted fabric and the thermo-acoustic performance of the sandwich structure was established.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"26 8","pages":"3657 - 3671"},"PeriodicalIF":2.3,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145145395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary objective of the current research is to evaluate the mechanical, thermal, and fire-retardant properties of epoxy/hemp composites with the inclusion of different weight proportions (3, 6, and 9 wt.%) of nanofillers like silicon dioxide (SiO<sub>2</sub>) and aluminum trihydrate (Al(OH)<sub>3</sub>). The composites were fabricated through the conventional hand layup method. Before fabrication, the hemp fibers were pretreated with hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) solutions to increase the adhesion between fibers and matrix. The results revealed that among the tested nanofiller concentrations, 6 wt.% of nanofillers significantly enhanced the mechanical properties like tensile (59.84 MPa for Al(OH)<sub>3</sub> and 66.14 MPa for SiO<sub>2</sub>) and flexural (21.74 MPa for Al(OH)<sub>3</sub> and 18.74 MPa for SiO<sub>2</sub>). The included nanofillers exhibit better OH⁻ interaction with hemp fibers, which helps to enhance the mechanical properties of hybrid composites. It was confirmed through FTIR and XRD analysis. According to the results of cone calorimetry, the incorporation of Al(OH)<sub>3</sub> and SiO<sub>2</sub> nanofillers reduces the peak heat release rates by up to 16.21%. It may happen due to the development of dense char layers and the release of water vapor between 300 and 400 °C via endothermal action. This mechanism helps to increase the flammability characteristics of epoxy/hemp-based hybrid composites. These enhanced epoxy/hemp-based hybrid nanocomposites are suitable for automotive, aerospace, electrical enclosures, and construction-based sectors.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"26 8","pages":"3601 - 3620"},"PeriodicalIF":2.3,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145144838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, self-crimping bicomponent fibers with PA/thermoplastic PA elastomer (TPAE) ratios of 35/65, 40/60, 45/55, and 50/50 were fabricated via melt spinning, and the effect of composition ratio on the properties of the fibers was investigated. The cross-sections of PA/TPAE bicomponent fibers varied from eccentric sheath-core to side-by-side, therein PA/TPAE interface changed from a curve to a straight line. The results showed that the increase in PA content contributed to the improvements in crystallinity, orientation, tensile tenacity, and thermal shrinkage strength, while that in TPAE content to the improvements in thermal shrinkage rate and elastic recovery rate. PA/TPAE bicomponent fibers had moderate mechanical properties and excellent elastic recovery, and hence can meet the requirements for textile processing. It is also noticed that the crimp behavior of PA/TPAE fibers was deviated from that of polyester-based side-by-side fibers as well as the predictions from current theories.

The findings demonstrate that increasing the number of ribs enhances energy absorption, while a higher d/D ratio generally reduces it.
