The sliding wear characteristics are systematically assessed using a pin-on-disc tribometer, with three parameters: a load of 10 N, a standardized wear track diameter of 70 mm, and a rotational speed of 300 r/min. This innovative study explores the impact of low graphene loading on the sliding wear and coefficient of friction of PETG composites, revealing how minimal graphene enhancements significantly decrease wear rates and friction levels. These insights facilitate the development of PETG-based materials with tailored tribological properties, ideal for high-wear applications in industries such as automotive and aerospace, where material longevity and performance are critically important. The investigation showed that the reinforcement of graphene in PETG reduced the coefficient of friction (CoF) and showed better results when graphene’s weight percentage increased from 0.06 wt% to 0.1 wt%. However, it did not help to minimize the specific wear rate (SWR) at the selected parameters for the sliding wear test. Out of all other concentrations of PETG/graphene composites, 0.04 wt% of graphene reinforcement showed a lower SWR but not less than pure PETG. Further, an investigation needs to be done for the discrepancies in the results.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"106 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The specific geometries examined were Schoen-Gyroid, Schwarz-Diamond, Schoen-I-WP, Schwarz-Primitive, and Fischer-Koch S. The experimental tests focused on subjecting these structures to compression loads. Samples were produced with a masked stereolithography (MSLA) printer. The samples had initial and end volume fractions (VFs) ranging from 20% to 60% in increments of 10%, with five varied relative densities. The Taguchi method is utilized to determine the optimal testing parameters, while the Analysis of Variance (ANOVA) test is employed to examine the data. The novelty of this paper is to comprehensively investigate the structural efficiency and versatility of TPMS for various applications by optimizing five different functionally graded TPMSs. The ANOVA findings highlighted the substantial impacts of Initial VF, Final VF, and TPMS type on the observed fluctuations in stress at the first peak. The Initial VF made a significant contribution, demonstrating 28.8% higher effectiveness than the Final VF. The TPMS type had a statistically significant effect on the amount of energy absorbed, revealing that different lattice types have abilities to absorb energy.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"8 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This innovative approach effectively addresses the diminishing availability of freshwater and river sand resources, as well as steel corrosion. This study explores the axial load carrying capacity and ductility of columns reinforced with combination of stainless steel bars and GFRP bars. The study conducted tests on 36 columns, varying in strengths (30 MPa, 40 MPa, 50 MPa), reinforcement types (GFRP bars (G group), stainless steel bars (S group), GFRP bars-stainless steel bars (GS group)), and reinforcement ratios (1.01%, 1.56%, 2.26%). The results exhibit positive correlation between the axial load carrying capacity of the column and both the strength grade and reinforcement ratio. In general, SSCC columns reinforced with stainless steel bars (S-SSCC) exhibit the highest axial load carrying capacity, followed by those reinforced with combination of GFRP bars and stainless steel bars (GS-SSCC), and SSCC columns reinforced with GFRP bars (G-SSCC) exhibit the lowest axial load carrying capacity. Furthermore, the axial load carrying capacity was determined utilizing ACI 440, CSA S806 and the finite element software ABAQUS. The results derived from the analytical model exhibited strong agreement with those obtained experimentally. Ductility analysis results suggest that columns with hybrid reinforcement can significantly improve ductility compared to those with only GFRP bars.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"36 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The magnitude of wrinkle wavelength varies from several millimeters to over one hundred millimeters. The detection and quantificationally evaluation of these defects are critical for structural integrity assessments. This study introduces a meso-mechanical model using the homogenization method, which calculates the effective stiffness of graded wrinkle defects. Finite element analysis (FEA) predicts a trans-scale out-of-plane displacement response in wrinkled laminates, with the maximum displacement ranges from nanoscale to millimeter scale. To address this, we utilized shearography (Speckle Pattern Shearing Interferometry) for nanoscale displacements and fringe projection profilometry (FPP) method for larger displacements. In FPP method, a displacement extraction algorithm was presented to obtain the out-of-plane displacement. Comparative analysis indicates that shearography possesses higher sensitivity, capable of detecting load responses as low as 10 N, whereas FPP requires a load range from 200 N to 1000 N. The FEA-validated measurement errors for shearography and FPP are within 3.3%–7.1% and 2.8%–10.5%. The comparison of measurement sensitivity and accuracy between shearography and FPP provides a quantitative reference for industrial non-destructive tests.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"2 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary objective is to analyze disparities in damage tolerance, damage mechanisms, displacements, deformations, energy absorption, and residual strengths resulting from LVIs followed by CAIs on dissimilar materials on opposite faces of the hybrid structure. The extent of damage is evaluated through Computed Tomography (CT) scans. During LVIs, impacts on the S glass face sheets side demonstrated different energy dispersion and absorption mechanisms, leading to variations in indent damage depths and widths across all impact energy levels, unlike the impact damages observed from the Kevlar side. During CAI testing, this difference becomes more evident, with Kevlar specimens (KS3 & KS5) showing greater indentation depths and narrower widths, and S glass specimens (SK3 & SK5) experiencing buckling. These effects are due to the unique damage absorption and dispersion properties of Kevlar and S glass. These variations prompted an in-depth investigation of the structure using CAI to comprehend damage tolerance and mechanisms under compressive loads. This study, unparalleled in existing literature, proposes hybrid sandwich structures with superior specific impact and residual strength compared to various composite sandwich structures documented in published literature, expanding their utility beyond radomes.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"87 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural integrity of the components plays an important role in analyzing the durability of the product which can be analyzed using modal analysis. This research study focuses on analyzing the effect of process parameters on the vibration damping characteristics of CF-PLA components produced by the FFF process. The Taguchi method is used to model the relationship between process parameters and vibration performance metrics. Based on the vibration study, the optimal process parameters were determined as 60% infill density, 0.08 mm slice thickness, and hexagonal pattern. This study shows that the natural frequency and damping increases with increase in infill percent but decreases with increase in slice thickness. The closely aligned values between the predicted and experimental results suggest that the developed model is effective in predicting the vibration characteristics of CF-PLA composites.

The failure mode and crack expansion of glass specimens after impact are studied. The influence of different factors (sandwich thickness, sandwich number, and sandwich position) on the impact resistance of explosion-proof glass is analyzed comprehensively. The results show that increasing the number and thickness of sandwiches can reduce the widening and expansion of microcracks, decrease crack connectivity, and effectively resist plastic damage to glass specimens. The appropriate position of the sandwich helps to improve the load-bearing capacity of the glass specimens. Therefore, the thickness of the sandwich, the number of sandwiches, and the position of the sandwich all have an impact on the impact load capacity and crack development of laminated glass. In addition, the impact resistance of laminated glass is positively correlated with the thickness of the PVB sandwich but shows different damage sensitivity to different impact velocities, with the best impact resistance under its medium velocity condition. This paper provides a significant theoretical foundation for establishing selection criteria for explosion-proof glass by examining the factors that influence its impact resistance, thereby enhancing its safety performance.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"15 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
