Despite its advantages, the productivity and mechanical performance of 3D-printed parts remain challenging areas. Hence, there is a growing interest in investigating the interplay between FDM build time and mechanical properties. Structural parameters such as layer thickness (Lt), raster angle (Ia), and air gap distance (Ifd) can exhibit conflicting effects on productivity and mechanical properties. This study employs GRA and VIKOR techniques for the multi-criteria selection of 3D printing, aiming to optimize both printing time and specific flexural properties of PLA/copper composite beams constructed in the edge direction. We compare the parameters selected by both methods and evaluate their impact on the responses. The behaviors of the two models differ: GRA optimizes two responses the specific stiffness ans specific strength, while VIKOR is more effective for minimising printing time. Both models select the lower raster angle of 0° as optimuim. Lt significantly influences printing time, being the primary parameter in the VIKOR method, whereas Ifd primarily contributes to mechanical properties.","PeriodicalId":15613,"journal":{"name":"Journal of Elastomers & Plastics","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141193151","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}

In determining the visual performance of optical products such as aircraft canopy, windscreens, etc., thickness distribution is crucial. Consequently, precise thickness measurement is the most essential aspect of quality control. To measure thickness, a variety of mechanical and optical measurement systems, in addition to several manual systems, are available. The manual intervention restricts the measurement system to lesser measurements and simplifies the system to simple geometries. Furthermore, post-processing of the image or point data is necessary to obtain thickness distribution using an optical measurement system. However, manual intervention is exceptionally time-consuming and may result in inaccurate outcomes. As a result, the current investigation put forth an algorithm based on machine learning to measure the precise thickness distributions from point data obtained through the measuring system. The algorithm’s functionality is illustrated through the thermoforming of a PMMA hemispherical dome at various forming pressures. Point data for thickness measurements of the hemispherical domes were acquired using the Rapid-I system of measurement. Utilizing the proposed algorithm, the thickness distribution of the hemispherical domes was measured accurately and efficiently.","PeriodicalId":15613,"journal":{"name":"Journal of Elastomers & Plastics","volume":"328 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141193079","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, studies reporting on the practical industrial control engineering of such reactors relying on thermal equilibrium mechanisms are scarce. This study presents a thorough analysis of a hot thermoregulating water (TRW) valve-jamming incident and interprets the related phenomena and parameter changes. The effect of the catalyst activity and variations in the liquid-phase quantities on the TRW valve action are investigated in depth, and a general explanation is provided by analyzing typical distributed control system data trends and proven deductive reasoning. Results indicate that the polymerization stability is maintained by two thermal pathways. The first pathway is related to the latent (condensate)/sensible heat (gas) extraction and polymerization heat of the materials, and the second is associated with the TRW system, specifically the cold and hot TRW branches. These pathways exhibited synergistic bidirectional effects. Finally, a series of innovative measures are proposed for internal and external operations to fully prevent and respond to TRW valve malfunctions and maintain overall polymerization stability. This study enhances the dependability of linear low-density polyethylene production through advanced process optimization utilizing the Unipol prototype and offers perspectives on system engineering for polyethylene production processes.","PeriodicalId":15613,"journal":{"name":"Journal of Elastomers & Plastics","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141193080","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}

These lattice structures are generated through Math Mod and simulated using Blender, with Autodesk Mesh mixer refining the STL file. The lattice fabrication employs PLA (polylactic acid). Comparative analysis is conducted against a high-density solid structure lacking lattice design. Optimal parameters for Schwarz P lattice are found to be 0.45 mm layer height, 0° build orientation, and 200°C extruder temperature, while for Schoen Gyroid lattice, 0.30 mm layer height, 0° build orientation, and 210°C extruder temperature.

The investigation of tensile properties revealed contrasting effects of TPU and HNT levels. Increasing TPU content to 30 wt.% led to a decrease in strength and modulus by 36% and 42% in turn, however resulted in a remarkable 338% improvement in elongation at break. Conversely, the addition of 3 wt.% HNT enhanced both tensile strength and modulus, although it caused a reduction in elongation at break. The results concerning fracture properties showed by incorporating TPU up to 30 wt.% EWF ( w e) and non-EWF ( βw p) rose by 459% and 178%, respectively. Additionally, the inclusion of 3 wt.% HNT further elevated the EWF compared to the compound containing 10 wt.% TPU without HNT.

Morphological analysis revealed a two-phase system in which the PVNR particles were dispersed in the AC matrix. Incorporation of TiO2 induced a finer blend morphology in which a part of the TiO2 was located at the interfaces of blend components. The tensile strength increased with initial TiO2 loading and reached its maximum at 10 php loading, with an improvement by about 127% over the blend without filler. However, further increase in filler loading reduced the tensile strength, and the filler tended to agglomerate at those higher loadings. Thermal stability and storage modulus in rubbery region of the blends containing TiO2 were also improved over the unfilled blend, due to the improved morphology and the hydrogen bonds between TiO2 filler and polymer matrix. TiO2 improved water wettability and adhesion of the blend. The maximum peel strengths on wood and metal substrates were about 120% and 26% larger than for the reference unfilled blend. Such drastic improvements suggest that the filled blends may find applications as coating materials.","PeriodicalId":15613,"journal":{"name":"Journal of Elastomers & Plastics","volume":"79 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140582977","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}

To date, there is no published work on optimization of process parameters for epoxidized canola oil production using the Taguchi method. In this study, the epoxidation of canola oil was performed using in situ-generated peracetic acid. Peracetic acid was formed by the reaction between acetic acid and hydrogen peroxide in the presence of a catalyst. The highest conversion to oxirane of 85% was achieved at a ratio of 2:1 of hydrogen peroxide to canola oil, a temperature of 65°C, and a stirring speed of 400 rpm. The Fourier-transform infrared spectroscopy (FTIR) characterization reveals the presence of the oxirane ring group, identified at a wavenumber of 1150 cm−1. Employing particle swarm numerical simulations, the results exhibit excellent agreement with the experimental data, thereby confirming the accuracy and validity of the kinetic model.","PeriodicalId":15613,"journal":{"name":"Journal of Elastomers & Plastics","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140582928","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}
