Depending on the location of the fracture, the fracture lines are brought end to end and fixed with plates and screws. Metallic implants are at risk of endogenous infection and there are inherent problems associated with their use, such as stress shielding phenomena, pain, and local irritation. After the bone has healed, a second surgery is needed to remove the metallic fixation. Considering these problems, it is important to use biodegradable plates instead of metal plates. Biodegradable fracture fixation plates degrade slowly in the human body, causing less pain and stress, and there is no need for a second procedure to remove the synthetic material. As these plates decompose, the load will also decrease. There are no toxic and mutagenic effects in an absorbable implant. However, there are some problems with the use of these implants, such as inflammatory response, rapid loss of initial implant strength, higher fracture rates, insufficient hardness of the implants, and weakness compared to metallic implants. In this study, biodegradable plates were designed for use in maxillofacial bone injuries, and treatment plates were prepared using extrusion and injection molding. Different proportions of trimethylene carbonate (TMC), poly-L-lactate (LPLA), poly(D,L-lactate) (DLPLA), polyglycolate (PGA) and beta-tricalcium phosphate (β-TCP) are mixed by extrusion to produce composites by injection molding. Plates were obtained. The degradation, morphological, thermal, and mechanical behaviors of the obtained products were examined.","PeriodicalId":20417,"journal":{"name":"Polymers and Polymer Composites","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141529983","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}

Scanning electron microscopy (SEM) analysis revealed improved filler dispersion and enhanced filler-rubber compatibility due to surface modification. The ∆Torque for compounds containing modified carbon black surpassed others by 13%. Mechanical properties such as tensile strength, elongation at break, modulus, tearing strength, and hardness were significantly influenced by filler type and surface modification. The harness (Shore A) increased to the value of 45 after surface amendment. Dynamic mechanical analysis (DMA) provided insights into storage modulus, loss modulus, and tan δ, showing the impact of filler type and surface modification. The utilization of coupling agent-modified carbon black decreased [Formula: see text] from −24°C to −30°C. Thermal gravimetric analysis (TGA) indicated consistent thermal stability across compounds, while solvent resistance improved with surface modification, as evidenced by swelling ratios. The thermodynamic analysis underscored the importance of filler type and surface modification on compound elasticity and flexibility.

This study focuses on optimizing the post-curing parameters for hybrid Ramie and Carbon fiber composites with the primary objective of improving tensile strength. Variations in post-curing temperature, post-curing time, and the number of synthetic fiber layers were systematically investigated across three levels using Taguchi design of experiments. The ultimate tensile stress was employed as the response parameter. Results indicate that post-curing temperature exerts a greater influence on tensile strength compared to post-curing time. A failure pattern of natural fiber followed by synthetic fibers was seen to happen progressively. A precise multivariable regression model was developed to predict the response for different combinations of post-curing parameters. Furthermore, employing particle swarm optimization revealed an optimal post-curing time of 12 h and an optimal temperature of 60°C. These findings contribute to the optimization of post-curing processes in hybrid fiber composites, thereby enhancing their mechanical properties.","PeriodicalId":20417,"journal":{"name":"Polymers and Polymer Composites","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141061082","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 composites were produced using the hand lay-up technique, and the mechanical, wear and physical properties of the prepared samples were evaluated. The fractured surfaces of the samples were examined using a scanning electron microscope. The results revealed that the source of the shell had an impact on the properties of the composites as eggshell-sugarcane bagasse particulate reinforced epoxy composites exhibited improved strengths, while snail shell-sugarcane bagasse particulate reinforced epoxy composites showed improved moduli. Optimal values were obtained for flexural and tensile strengths at 15 and 18 wt%, respectively, while flexural and tensile moduli were optimal at 12 and 15 wt%, respectively. Eggshell-sugarcane bagasse particulate reinforced epoxy composites demonstrated an optimal impact strength value of 21.81 J/m2, while snail shell-sugarcane bagasse particulate reinforced epoxy composites showed optimal results in all other properties mostly at 20 wt%.

The force coefficients in the model, which include friction angle, shear plane angle, shear strength, and rebound height, can be characterized by the fiber orientations ranging from 0° to 180°. The accuracy of the model was confirmed through experimental verification. The results indicate good agreement between the predicted and experimental values, with relative errors below 14.8%, except for the thrust force at 90°. Additionally, the study examined the influence of rake angle and flank angle on the cutting force, revealing two critical points in the predicted cutting force curve throughout the fiber orientation. These turning points shifted with changes in the rake angle. For instance, the value of the first critical point changes from 60° to 45° when the rake angle range shifts from [0°, 5°] to [10°, 15°]. This indicates that a larger rake angle facilitated an earlier transformation of chip formation mode, leading to a decrease in cutting force. Furthermore, the cutting force decreased as the rake angle increased between the two turning points. The impact of the flank angle on the cutting force was determined to be minimal, and the turning points’ positions remained consistent as the flank angle increased.","PeriodicalId":20417,"journal":{"name":"Polymers and Polymer Composites","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140628145","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}

Recently introduced, the floatation technique has emerged as a method for segregating specific plastics, such as polystyrene (PS), polyethylene terephthalate (PET), and polyvinyl chloride (PVC), from mixed waste streams. This separation process involves the utilization of traditional dual depressants (chemical agents). The study investigated the impact of pre-microwave irradiation of plastic surfaces at varying microwave output powers (20-100%) on the floatation behavior of each plastic. Additionally, the influence of depressant concentration (200-1600 mg/L) on plastic floatation was examined. The results revealed that pre-microwave irradiation at different output powers and varying depressant concentrations significantly affected the sink-float behavior of the studied plastics, with the exception of PET. It was observed that the microwave irradiation altered the number and type of active sites on the plastics' surfaces. Notably, there was no discernible regular trend in the flotation of plastic with an increase in microwave output power. The outcomes were substantiated by conventional identification techniques, including contact angle (θ) measurement, scanning electron microscopy (SEM) images, and attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR) spectra analysis. Equations derived through the use of the design of experiment software (Design-Expert®) demonstrated a commendable alignment between the predicted and actual values of plastic flotation.
