The Taguchi design is used to investigate the effect of process parameters on Young’s modulus and yield strength of specimens fabricated as per ASTM D-638. A two-level fractional factorial design supplements the L27 design results. The results show that the layer height, infill pattern, density, and raster angle significantly affect the tensile behavior. The apparent Young’s modulus is also significantly affected by the interaction between layer height, infill pattern, and infill density.","PeriodicalId":260382,"journal":{"name":"Journal of Elastomers & Plastics","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139624338","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}

Poly(vinyl alcohol) (PVA), cellulose nanofiber (CNF), and 2,5-furandicarboxylic acid (FDCA) are typical examples among these environmentally friendly molecules. In this study, we investigated the synergistic effects of CNF reinforcement and crosslinking with FDCA on the properties of PVA. The composite films were prepared via a straightforward mechanical-dispersion method, wherein CNF was incorporated into a PVA solution and subsequently crosslinked with FDCA. Comprehensive characterizations, including Attenuated Total Reflection-Fourier Transform Infrared Spectroscopy (ATR-IR), X-ray diffraction (XRD), Thermal Gravimetric Analysis/Differential Thermal Gravimetric Analysis (TGA/DTGA), Differential Scanning Calorimetry (DSC), tensile testing, and morphological studies, were performed to assess the impact of these modifications. Our findings revealed significant enhancements in the mechanical and thermal properties of the composites. Notably, the tensile strength of the PVA-c-FDCA/CNF composite with 2% CNF reached 37.08 MPa, representing a twofold increase compared to both crosslinked PVA (16.84 MPa) and unmodified PVA (14.57 MPa). TGA/DTGA analysis demonstrated improved thermal stability, with the degradation temperature reaching 371°C, compared to the 298°C observed for PVA. DSC and XRD results indicated a reduction in PVA crystallinity after crosslinking and blending with CNF. Scanning electron microscopy (SEM) images showed good compatibility between PVA and CNF. This study underscores the potential of CNF reinforcement and FDCA crosslinking as a viable strategy to enhance the mechanical properties of PVA-based materials.","PeriodicalId":260382,"journal":{"name":"Journal of Elastomers & Plastics","volume":"59 45","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139384555","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}

The current work basically focused on the influence of Pistachio shell particles (PSP) on mechanical performances of kenaf(K)/glass(G)/polyester hybrid laminates. Usual hand layup technique is used to fabricate different stacking order laminates such as KKKK, KGGK, GKKG, KGKG, and GGGG with PSP filler concentration of 1 wt%, 3 wt% and 5 wt%. The experimental findings reflect a noticeable improvement in mechanical properties with gradual inclusion of PSP filler. The KGKG laminate with 5 wt% of PSP shows an optimum tensile strength of 127.35 MPa and highest micro-hardness value of 21.35 HV, whereas KGKG laminate with 3 wt% of PSP exhibits a maximum flexural of 112.42 MPa and impact strength of 75.59 KJ/m2. The numerical analysis is also been carried out to validate the experimental results using ANSYS 19.0 software. On comparing the data of numerical analysis with experimental values, the deviation of result is found to be within the limit of 5% to 10%. Furthermore, the result of Thermo Gravimetric Analysis (TGA) has shown a highest amount of residue of 31.22% at 700°C in case of GKKG laminate with 5% of PSP filler. Again, at 5 wt% of PSP filler, the GKKG laminate has shown a lower water intake capability of 3.5% in comparison to KGKG and KGGK laminates at saturation time of 14 days.

The results reveal that the addition of glass fiber to PPLSF significantly enhanced the mechanical performance of the laminates.

Problem Statement: An attempt has been made to develop and investigate the environment friendly and biodegradable composites based on jute fiber and PLA composite. Materials and Method: The erosion wear performance was assessed on Air-jet erosion tester. The design of experiments was prepared as per Taguchi orthogonal array L16 under for different factors of impact velocity, impingement angle, erodent size and jute fiber fraction and level of each factor was kept four. ANOVA was applied to find the best significant factor affecting erosion rate of composite. Main Results: The finding of results indicated that the density significantly increased with the addition of jute fiber and in parallel, it indicated the increment in the void content. The mechanical properties like hardness, tensile strength, flexural strength, impact strength and fracture toughness of PLA based composite reinforced with 15 wt.-% jute fiber were increased by 59%, 233%, 42%, 62% and 168% respectively. On the other hand, the thermal conductivity of the composite was decreased by 31% with the addition of 15 wt.-% of jute fiber. The minimum erosion wear rate was obtained for 15 wt.-% of jute fiber under impact velocity of 35 m/sec and angle of impingement of 90° and erodent size of 250 µm. Finally, ANOVA concluded that the impact velocity and jute fiber fraction played the most important role in influencing the erosion wear rate of PLA composite. Recommendation: For many construction and structural applications, jute PLA/fiber composite can be suitable due to excellent mechanical properties and low thermal conductivity.","PeriodicalId":260382,"journal":{"name":"Journal of Elastomers & Plastics","volume":"7 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138979835","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}

Phthalates are small molecule plasticizers of PVC, which are easy to volatilize and migrate while improving the processing properties of PVC. We propose alternatives based on phenolic resin prepolymer modified by cardanol (CPF), which were added to PVC as reactive plasticizer and can improve the processability of PVC. The effects of CPF on the rheological properties and migration resistance of plasticized PVC were studied, and the changes in the physical properties of blends were also discussed. The results showed that the viscosity of PVC melt can be reduced by two orders of magnitude by adding 30 wt% prepolymers at 180°C compared with PVC without CPF, which indicated that CPF can be used to reduce the processing temperature of PVC. The test results of migration resistance showed that the mass loss rate of the blend with 30 wt% prepolymers was less than 1 wt% after curing, however, the mass loss rate of the blend with 30 wt% dioctyl phthalate (DOP) was more than 12% after 5 days of testing. When the PVC/CPF mass ratio was between 60/40-70/30, the maximum values of tensile strength and elastic modulus are 64.4 MPa and 3.2 GPa, respectively, which showed the addition of CPF could significantly improve the tensile strength and elastic modulus of the blend system compared with PVC without CPF. Especially, the thermal stability of CPF is better than that of DOP, CPF exhibits the maximum thermal decomposition temperature (410°C), higher than that of DOP (170°C), which can adapt to higher processing temperature.","PeriodicalId":260382,"journal":{"name":"Journal of Elastomers & Plastics","volume":"23 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139262509","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}

Improvement in various aspects of the control sample including crosslink density calculated based on the swelling test and tube theory, bound rubber content, and physico-mechanical properties was observed for nano-SiO2 loading below 10 phr due to its effective role in refinement of filler dispersion state and enhancement of rubber-filler interactions. However, most of the properties were sacrificed at 15 phr nano-SiO2 loading even with respect to the control sample which emphasized the effectiveness of nano-SiO2 within an optimum loading. Moreover, nano-SiO2 at optimum loading exhibited great improvement in initial decomposition temperature about 50°C, considerable improvement in rolling resistance (more than 8%) and enhancement in wear resistance which could be crucial for tire tread manufacturers.","PeriodicalId":260382,"journal":{"name":"Journal of Elastomers & Plastics","volume":"7 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117342617","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}

Concurrently, environmental changes, such as temperature and humidity variations, can impact their stress response to deformation. This study investigates the effects of material layers within neoprene samples on mitigating these environmental changes. While the presence of an intermediate layer proves effective against temperature and humidity influence, it fails to block the impact of increasing high strain rates. Moreover, the different humidity levels at room and elevated temperatures do not significantly alter the mechanical behavior of filled neoprene samples compared to pure neoprene. Notably, in unfilled neoprene, an increase in humidity levels, other than an absolutely dry environment, leads to a notable stress level rise at room temperature, while under elevated temperature conditions, there is a significant stress decrease with increasing humidity. However, neoprene filled with polyester/cotton or nylon displays resilience to diminishing mechanical behavior under various temperature and humidity regulations, indicating that the material layer within these samples effectively “protects” the rubbers from potential stress lapses observed in unfilled neoprene. While a high strain rate compression affects the behavior of the filled variants significantly, increasing humidity and temperature have minimal impact on their stress levels. These findings offer valuable insights into the dynamic responses of elastomers to environmental changes, highlighting the advantages of using filled rubbers in diverse applications.","PeriodicalId":260382,"journal":{"name":"Journal of Elastomers & Plastics","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127089903","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}
