Various Kevlar powder concentrations were integrated into the polymer matrix, and the composites were evaluated through tensile, flexural, toughness, hardness, and surface roughness tests. The results demonstrated that Kevlar reinforcement significantly enhanced tensile strength and toughness by 32.55 % and 9.24 %, respectively, while hardness improved by 8.98 %, contributing to greater wear resistance. Additionally, surface roughness analysis revealed that pure PLA and ABS exhibited the smoothest surface finishes; however, the S3 (95 % ABS + 5 % Kevlar powder) sample, achieved the most favorable balance between mechanical performance and surface quality, making it the optimal formulation among the tested specimens. Scanning electron microscopy (SEM) confirmed uniform Kevlar dispersion, leading to better structural integrity and reduced defect formation. Surface topography analysis showed that the S3 composite exhibited the lowest mean surface height (0.5373 nm) and the largest mean particle area (44.74 μm<sup>2</sup>), suggesting a well-distributed reinforcement phase. However, S4 (90 % ABS+10 % Kevlar powder) sample displayed a significantly higher mean surface height (230.1 nm) and a reduced mean particle area (11.07 μm<sup>2</sup>), indicating increased surface irregularities and imperfections. These findings highlight the potential of Kevlar-reinforced ABS/PLA composites for lightweight, high-strength applications in the automotive, aerospace, and protective equipment sectors.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"11 ","pages":"Article 100510"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144203184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a solution, recycled aggregate concrete has emerged as a practical substitute. Predicting strength accurately is essential for cutting design time and expenses while limiting material waste from numerous mixing tests. Machine learning methods tackle structural engineering issues, including the prediction of Splitting Tensile Strength (STS). In this study, used four novel machine learning models such as Random Forest Regression (RFR), Extreme Gradient Boosting (XGBoost), Gradient Boosted Regression Trees (GBRT), and Bagging Regressor (BR) with grid search for hyperparameter tuning to forecast the splitting tensile strength of fiber-reinforced recycled aggregate concrete (FRRAC). The machine learning models demonstrated high reliability in predicting splitting tensile strength, including robust values for R-squared (R<sup>2</sup>), Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE) and Mean Absolute Error (MAE). The prediction performance of the GBRT models showed the greatest R<sup>2</sup> value of 0.95 during the training stage and R<sup>2</sup> value of 0.83 during the testing phase. The XGBoost, RFR and BR models found R-square values were 0.822, 0.781 and 0.824 at the testing phase, respectively. Moreover, the RFR, BR, GBRT, and XGBoost model RMSE values were found to be 0.333, 0.298, 0.276, and 0.3004 at the testing phase, respectively, where the GBRT model RMSE value was found to be good. The GBRT model showed the lowest uncertainty value of both phases, with values of 0.619 and 0.597 for the training and testing phases, respectively. Furthermore, SHapley Additive exPlanations (SHAP) analysis found that CR, and additional of Fiber were the most influential input features and replacement percentage of CR (%) and RCA Absorption capacity (%) inputs had the lowest impact of Fiber-Reinforced Recycled Aggregate Concrete for predicting splitting tensile strength. These results indicate that the suggested technique can significantly contribute to sustainable construction practices by precisely predicting splitting tensile strength.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"11 ","pages":"Article 100507"},"PeriodicalIF":0.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, locally produced Portland cement in Ghana falls short of meeting the rigorous standards required for oil well cementing. The study examined the effects of adding coconut fiber and fiberglass to the cement slurry to improve its rheological and compressive strength properties. The free fluid content, rheological properties, and compressive strength of the filler incorporated in local Portland cement slurries were monitored. The outcome of the experimental procedures indicates that incorporating these fibers significantly enhances the mechanical performance of the cement, with a marked increase in compressive strength values ranging from 6.31 MPa (0 % fibers) to 14.60 MPa (1.25 % coconut fiber and 1.25 % fiber glass) which meets the API requirement for an oil well. The rheological properties indicated an increased plastic viscosity ranging from 58 mPa s (0 % fibers) to 91.5 mPa s (1.25 % coconut fiber and 1.25 % fiberglass) and decreased yield point ranging from 31.36 pa (0 % fiber) to 22.74 pa (1.25 % coconut fiber and 1.25 % fiberglass). The free fluid content decreased from 1.39 % (0 % fiber) to 0.75 % (1.25 % coconut fiber and 1.25 % fiberglass).
