Therefore, there is a need to improve the protection of the composites from the various agents and improve their mechanical properties. This study's objective was to assess the impact of bamboo/kenaf hybrid fibres, Maleic Anhydride Grafted Polypropylene (MAHgPP), Hinder Amine Light Stabiliser (HALS), and Calcium Carbonate (CaCO3) additions on tensile strength and hardness at various levels, as well as their interactions on polypropylene (PP) composites. The manufacturing of the composites was accomplished through the compression molding process. The study was conducted using Taguchi orthogonal array L27 with fiber, MAHgPP, HALS, and CaCO3 as input parameters. A robust optimization technique for product and process design (Taguchi method ) was used to optimize the parameter settings for the tensile strength and hardness of the composite. Results showed that the tensile strength of the resultant composite ranged from 37.60 MPa to 53.57 MPa; while the hardness value ranged from 70.32 (Shore A) to 93.03 (Shore A). The optimized composite had a tensile strength of 49.12 MPa and a hardness of 79.85 (Shores A). The factors settings that gave the combined optimum tensile strength and hardness for the bamboo/kenaf fiber are 36.87% fiber, 5% MAHgPP, 1% HALS, and 3% CaCO3. therefore the best tensile strength and hardness performance of the composite was obtained from the optimum setting.","PeriodicalId":485252,"journal":{"name":"Open Journal of Engineering Science","volume":"39 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135934616","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}

This entails disposing of sludge in such a way that it will not be harmful to the environment due to the chemicals used during the treatment of the water. The disposal of sludge conditioned by chemical polymers has an adverse effect on health and the environment. The use of natural polymers (such as wool polymer) has been explored to reduce adverse effects that come from chemical polymers (polyurethane). Elemental compositions of Moringa Oleifera were distinctive using ultimate analysis, proximate Analysis, Fourier Transform Infrared Spectroscopy, and energy-dispersive X-ray fluoresce. Characterization was done to examine the composition, functional characteristics, and physico-chemical properties of moringa oleifera . The proximate result showed that Moringa oleifera contains 36.34% of crude lipids, 3.78% of moisture,4.08% of Ash, 4.70% of crude fibre, 29.56% of crude protein, and 21.54% of carbohydrate. The ultimate result showed that carbon contains 45.86% and hydrogen has 1.96%. FTIR Spectrum of Moringa Oleifera showed C≡N(carbon-nitrogen) C=N and S-S (Sulphur-Sulphur) stretching bond. FT-IR spectra showed the presence of protein and lipids components. The FTIR Spectrum of the dry sludge showed many vibrations indicating some functional groups like N-H in Amides, alcohols and amines O-H, (Oxygen-hydrogen) C≡C bond C=N, C-H(Carbon -Hydrogen)O-CH3, P-N-C, C-H in aldehydes and acids C=O in Carboxylic acids, and S-S bond ED-XRF showed the elemental composition of Moringa Oleifera; 0.018% Fe, 0.001% Cu, 0.003% Al 9.00%, 0.038% Mg etc. and that of the dry sludge as 9.22%, Fe2O3, 0.572% CuO, 9.63% Aluminum oxide, 29.96% Silicon Oxide, 2.57% magnesium oxide. Turbidity of the treated sample was reduced to the level of Nigerian standard (5NTU). Moringa Oleifera was discovered to be a viable and affordable alternative for conditioning of water treatment sludge.","PeriodicalId":485252,"journal":{"name":"Open Journal of Engineering Science","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135924805","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}
