Research on GFRP composites with nano Active Filler of Pumice Particle (nAFPP) and Sodium Silicate (SS) fillers has been conducted to evaluate the composites with FTIR, thermal properties (TGA-DSC), flammability performance (ASTM D 635), and emission (smoke particle matter). The GFRP composite with 5 wt.% nAFPP and 5 wt.% SS exhibits the highest burning residue at 27.5% among the others, whereas the filler-free composite shows the lowest burning residue at 20.99%. The DTG test indicates that composites with fillers decompose longer than those without. All composites with fillers exhibit amorphous nAFPP, indicated by sharp exothermic curves of crystallization. The DSC test shows higher heat flow during crystallization and melting, indicating exothermic and endothermic processes, respectively. Adding SS filler offers greater flammability resistance advantages than nAFPP. The filler-free composite has the lowest flammability resistance with a burning rate of 0.494 mm/s, whereas the specimen with 7 wt.% nAFPP and 3 wt.% SS achieved the best flammability resistance with a burning rate of 0.215 mm/s. The SS proves more effective in enhancing flammability resistance. The use of fillers reduces smoke-particle pollutants in GFRP composites, and SS is a better inhibitor of particle matter in smoke. Industries have an opportunity to improve GFRP composite products, and further investigation is needed to achieve the excellence of GFRP composites.</p>\u0000 </div>","PeriodicalId":12186,"journal":{"name":"Fire and Materials","volume":"50 5","pages":"547-557"},"PeriodicalIF":2.2,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148662684","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}

Recycling PA66 waste not only helps alleviate environmental pollution caused by PA66 waste but also reduces the consumption of fossil resources, which has important practical significance. In this paper, PA66 waste and phytic acid were used as precursors to prepare PA66-based carbon dots (66CDs), a novel zero-dimensional carbon nanomaterial, through a solvent-free one-step pyrolysis method. The optimal excitation and emission wavelength of the prepared 66CDs is 410 nm and 500 nm, and the fluorescence quantum yield is 25.42%. The average particle size of 66CDs is 3.30 nm, and the lattice spacing is 0.21 nm, with surface functional groups such as –OH and –NH<sub>2</sub>. Subsequently, the as-prepared 66CDs were used for flame retardant finishing of polyester fabrics through double-dip-double-nip method. When the concentration of 66CDs is 10 g/L, the weight gain of the polyester fabric is 1.69% and the limit oxygen index value reaches 29%. The ignition time of finished polyester fabric reaches 219 s with an improvement of 10.60% compared to pure polyester fabric, and the damage length decreased 39.20% compared to pure PET, thus enhancing fire safety of polyester fabric. The study on the flame retardant mechanism indicates that 66CDs play a role in quenching free radicals and promote the formation of a dense char layer in the polyester fabric, thereby achieving the flame retardant effect.</p>\u0000 </div>","PeriodicalId":12186,"journal":{"name":"Fire and Materials","volume":"50 5","pages":"576-586"},"PeriodicalIF":2.2,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148662572","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}

Thus, it poses a danger to occupants, especially those who need assistance to evacuate. Improved fire properties of upholstered furniture may delay or prevent the fire development. Hence, available time for occupants to escape will increase. Fire safety measures should be accessible, easily applicable, cost efficient, and without harmful effects on health and the environment. Results from small-scale screening tests and large-scale fire experiments of typical upholstery materials on the Norwegian market are presented. The materials were polyurethane foam covered with three different fabrics: 100% cotton, and two different cotton/polyester blends. The covers were tested untreated, with application of two types of fire retardants, and covered with a thick wool blanket. The test results from a complete armchair show that the simple measures were able to delay the fire growth, where the fire-retardants gave the longest delay. This indicates that the fire behaviour of upholstered furniture may be efficiently improved by application of simple measures. This could be particularly useful in residences where a higher level of fire safety is needed, for example in homes for at-risk persons in case of fire.</p>\u0000 </div>","PeriodicalId":12186,"journal":{"name":"Fire and Materials","volume":"50 5","pages":"479-498"},"PeriodicalIF":2.2,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148662671","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 focuses on the critical task of selecting the most suitable fire suppression system for industrial facilities. To achieve this, we identify three main criteria—effectiveness, safety, and operational considerations—along with thirteen subcriteria to guide the selection process. The Spherical Fuzzy Analytic Hierarchic Process (SF-AHP) method is employed to determine the weights of these criteria through expert evaluations, followed by the Spherical Fuzzy Evaluation based on Distance from Average Solution (SF-EDAS) method to rank various fire suppression alternatives. A case study is conducted in a facility dedicated to producing plastic animal cages as a practical application of this methodology. This is a high-risk environment due to the explosive nature of the materials used. The results highlight Reaction Time as the most critical factor, followed by Impact on Operations, Flexibility, and Personnel Protection. In this case study, the clean agent system ranked highest, demonstrating its effectiveness in meeting the facility's specific needs.

This study, using MODIS data from 2001 to 2022, investigates the spatiotemporal dynamics, driving factors, and predictive performance of FVC in Anhui Province of China. The results show that over the past 20 years, FVC in Anhui has significantly increased, with more than 80% of the region showing an upward trend, and 47.72% of the area experiencing highly significant increases, while less than 7% showed a decline. The annual mean FVC increased from 0.64 to 0.74, exhibiting a clear spatial gradient of “high in the south, low in the north.” Feature correlation analysis revealed that temperature and evapotranspiration are the main environmental drivers of FVC. Temperature can promote the growth of vegetation and increase its coverage, while evapotranspiration is closely related to regional water stress. In the established predictive modeling, the XGBoost algorithm outperformed random forest and ridge regression, demonstrating the best predictive performance on the validation set (<i>R</i><sup>2</sup> = 0.83). While the individual analytical methods employed are well-established, the primary innovation of this study lies in constructing an integrated framework that bridges traditional long-term spatiotemporal statistics with advanced ensemble machine learning. This methodological integration successfully transitions regional vegetation analysis from retrospective observation to high-precision dynamic forecasting. Ultimately, by accurately forecasting vegetation trends under varying thermal and moisture conditions, this research fills a critical gap in Anhui Province, providing robust, data-driven support for climate change adaptation strategies, targeted afforestation planning, and sustainable land-use policymaking.</p>\u0000 </div>","PeriodicalId":12186,"journal":{"name":"Fire and Materials","volume":"50 5","pages":"528-546"},"PeriodicalIF":2.2,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148662683","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}
