Item Production and Characterization of Asbestos Free Brake Pads From Kenaf Fiber Composite(Faculty of Engineering and Technology, Adeleke University, Ede, Nigeria., 2020) Elakhame, Z. U.; Shuaib-Babata, Y. L.; Jimoh, S. O.; Bankole, L. K.; Ambali, I. O.Brake pads are the most important t components of an automobile braking system majorly for deceleration of vehicles by transforming the kinetic energy of the vehicle to heat energy. The performance of a brake pad depends on the frictional material that is used in its formulation. Carcinogenic nature of asbestos fibers in brake pad which is dangerous to human health makes its use no longer acceptable, and this has led to development of new asbestos-free friction materials for brake pads. This study focused on the production of brake pads using kenaf fiber composite that are eco-friendly following the powder metallurgy methods. The properties of the produced brake pads, such as comprehensive strength, wear rate, water absorption and flame resistance were tested to ascertain its suitability. The results from the tests confirm that the produced brake pads compared favorably with commercial brake padItem Utilisation of Indigenous Ceramic Raw Materials for the Production of Water Closet(SCIENTIFIC RESEARCH, 2020-09) Elakhame, Z. U.; Obe, Y. O.; Shuaib-Babata, Y. L.; Bankole, L. K.; Omowunmi, O. J.; Ambali, I. O.; Akinsanya, O. O.; Unachukwu, A. J.; Adeyemo, R. G.; Ikusedun, MThe fact is that Nigeria ceramic raw materials are underutilized as a result of inadequate information on the materials which limits the local production of water closet. The emphasis of this research was on the suitability of the physio-chemical properties of the abundant locally sourced ceramic raw materials from South-west Nigeria. The selected locally sourced raw materials included: kaolin, feldspar, silica and ball clay. The Physical properties carried out on the specimens produced include chemical analysis, shrinkage, porosity, bulk density, modulus of rupture, plasticity and viscosity. The physical property tests were done in accordance with (ASTM C). Standard and the chemical composition were identified by AAS spectrometer. However, the ratio of kaolin, feldspar, quartz and ball clay was varied in five major formulation represented as A, B, C, D and E. The clay, kaolin, quartz and feldspar used in this study were found to belong to alumina-silicate group suitable for the production of standard water closet. The samples’ properties met the required standards; hence, the materials were found suitable for production of water closet of acceptable standards. Composition A specimen gives the most suitable proportions for the production of water closet at 40% of kaolin, 25% of feldspar, 10% of quartz and 25% of ball clay respectively.
