Non-structural uses account for a significant portion of concrete production. Foamed concrete (FC) is incredibly porous, and as the number of voids increases, the material's thermal characteristics decrease. Since these uses need a substantial amount of concrete, researching them might yield useful information for optimizing concrete's material efficiency and making better use of its waste products. FC is excellent in compression but poor in tension because it creates multiple microcracks. FC cannot withstand the tensile stress induced by the applied forces without additional reinforcement elements. Hence, this research investigates the mechanical properties of polypropylene (PP) fibers based foam concrete. The utilization of effective materials such as cement, flyash, silica fume and PP fibre were used in this investigation. In this study, a novel invention is proposed for designing and strength prediction of foam concrete and find out the strength properties such as compressive strength, split tensile strength and flexural strength of fibre reinforced foam concrete were determined and the experimental and predictive value of compressive strength were also determined with the help of python. The results provide a clear idea of the efficient use of fly ash and silica fume for the manufacture of light weight based products that promote profitability, sustainability and entrepreneurship for youth in developing countries such as India, and it is important by conserving natural resources through savings in the consumption of cement and aggregates.","PeriodicalId":18262,"journal":{"name":"Materials Science Forum","volume":" 46","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140687185","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}

Kini","doi":"10.4028/p-duyo7m","DOIUrl":"https://doi.org/10.4028/p-duyo7m","url":null,"abstract":"Emerging trends in extrusion-based additive manufacturing (AM) focus on improving the mechanical performance of pristine polymers with high strength reinforcing materials. Prominent reviews have indicated a heavy dependence on PLA polymer for fused deposition Modeling (FDM) based studies. To promote biodegradability, the effect of natural fibres as reinforcement has been widely researched in the literature. However, it is noted that discontinuous natural fibre reinforcement yields negative or negligible improvement in the strength and modulus of FDM-based biocomposites. Hence, an attempt to hybridise FDM with a conventional composite manufacturing method was made in this study by cladding natural fibre reinforcement over FDM-based polymer. Tensile and flexural test coupons were additively manufactured by FDM and reinforced with a skin of bi-directional woven basalt fibre through compression moulding. A 90% improvement in tensile strength and a similar significant increase in flexural strength was observed. Further, an average increment of 46.38% and 237.24% in tensile and flexural modulus, respectively, was achieved through this manufacturing technique. In conclusion, a drastic improvement in mechanical performance can be obtained through the hybridisation of manufacturing methods and needs further investigation towards the compatibility of adhesive materials with FDM polymers.","PeriodicalId":18262,"journal":{"name":"Materials Science Forum","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140686125","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, close loop recycled aluminium alloys can be adversely affected by impurities and alloying elements present in the recycled feedstock. In this study, the influence of three composites, namely alumina (Al2O3), ferric oxide (Fe2O3), and manganese (Mn), on the properties of recycled aluminium taldon scraps was investigated to enhance the tensile behaviour of the alloys. The effects of these composites on the mechanical properties, microstructure, and corrosion behaviour of the recycled aluminium alloys were evaluated through experimental characterization techniques. The results showed that the addition of these composites had a significant influence on the properties of recycled aluminium alloys, providing insights into the potential for improving the performance of recycled aluminium alloys through composite additions. The addition of Al2O3 enhanced the tensile strength by 44.18 % and the variation can be attributed to the strengthening of the dendritic zones by the formation of α-Al.","PeriodicalId":18262,"journal":{"name":"Materials Science Forum","volume":" 40","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140687756","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}

Despite being adaptable, the procedure currently works with a restricted number of materials, mostly thermoplastic polymers. 3D printing fused deposition modeling (FDM) provides opportunities to produce complex components relatively quickly in small batch with a high degree of flexibility for both manufacturer and researcher. Process parameters in FDM like infill pattern, infill density, printing speed, raster angle influences the mechanical properties of a printed parts. In this research study, a novel approach on the internal structure of 3D printed parts say combined infill pattern (Triangles & Octet) on a single part has been introduced and mechanical properties like tensile test, flexural strength, compression strength and hardness were measured. Specimens were printed in Acrylonitrile butadiene styrene (ABS) as per ASTM standards by FDM technology with different infill densities of 60%, 80% and 100% by XY build orientation. SEM analysis was made to analyze the morphological and inter bonding of different infill patterns. The results show that mechanical performance was inflated by an increase in infill density.","PeriodicalId":18262,"journal":{"name":"Materials Science Forum","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140688907","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}
