A brake system is highly imperative for the safe control of an articulated automobile. One of the major components of the automobile system is brake pad which is currently imported into the Nigerian market. This study was aimed at producing brake pads from locally available materials to serve as an alternative to imported pads. Samples of brake pad...

This study examined the appraisal of wind resources of Ilorin, Nigeria for vortex-induced wind turbine power generation and off-grid electrification. The technical potential of Modern-Era Retrospective Analysis for Research and Application, version 2 (MERRA-2) was employed as a tool to generate an estimated wind resource of Ilorin city, using five...

This study examined the morphology and microstructural evolution of resin-bonded palm kernel and coconut shell grain-based abrasive grinding wheels and their physico-mechanical and tribological properties. Raw palm kernel shell (PKS) and coconut shell (CNS) samples were obtained, sorted, sun-and oven-dried, pulverised, and screened into fines of 25...

Due to the challenges associated with using crude oil-derived phenolic-or thermoplastics-based materials, agro-based composites have been used as alternative abrasive grains for abrasive tool manufacturing. This paper examines the morphology and physico-mechanical properties of resin-bonded palm kernel shell (PKS) and coconut shell (CNS) grain-base...

The need for improved metallic materials in terms of physicomechanical, microstructure, and corrosion properties has necessitated the need to form metal matrix composites. This article adopted the stir casting procedure and used wood particles (WP) to reinforce aluminum alloy at different volume fractions. The corrosion properties of the aluminum m...

Sun is the main source of solar energy, and the energy it releases to the Earth’s surface in one hour is more than what the whole planet consumes in a year. This present work is about characterizing novel material that can be used as energy storage and diffuser in constructing flat plate solar collector. Materials used are clay and granite dust obt...

This research reports on the suitability of Agricultural bi-products as low temperature thermal insulating materials to replace synthetic insulating materials like polyurethane used in food warmers and ice coolers. Coir and sugarcane bagasse chosen for this research was based on literature review and local availability of materials. Coir was obtain...

Steels are basically classified based on their carbon contents. In view of this, the processing of steels is greatly affected by their composition, particularly their carbon content. This paper reports on the machinability of three different steels with varying carbon contents. The steel samples were sourced from Owode metal market in Ilorin, Kwara...

Quenching and tempering are processes that strengthen and harden materials like steel and other iron-based alloys. Conventional heat treatment procedures for producing martensitic steels generally involve continuous and rapid cooling of an austenitized specimen in some types of quenching media such as water, oil, or air, in which the properties of...

This research investigated the relaxed densities of biomass briquettes produced from combination of sawdust and charcoal. Cassava starch gel and orange waste were used as binder for briquetting. Five sizes; 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm and 1.0 mm and mixing ratios 50:50, 60:40, 70:30, 80:20 and 90:10 of biomass materials, sawdust and charcoal wer...

This paper reports on the investigation of thermal properties of Kapok, Coconut fibre and Sugarcane bagasse composite materials using molasses as a binder. The composite materials were moulded into 12 cylindrical samples using Kapok, Bagasse, Coconut fibre, Kapok and Bagasse in the ratios of (70:30; 50:50 and 30:70), Kapok and Coconut fibre in the...

Globally large scale industries are in the fore-front of industrial engineering and for Small Medium Enterprises (SMEs) to remain competitive in the global competition which is largely controlled by large scale enterprises. The search for new revenue sources and implementing new cost cutting initiatives should be adopted by SMEs. To sustain their c...

The importance of various form of heat treatment operations on medium carbon steel in order to forester the problem that may arise in making a wrong choice of these steel materials or faulty heat treatment operations which may give rise to serious disruption in terms of human safety, higher cost and untimely failure of the machine components is of...

This study was carried out to on medium carbon steel subjected to various form of heat treatment operations, by assessing the temperature distribution during the machining process. The model of oblique band heat source, moving in the direction of cutting in an infinite medium with an appropriate image heat source, was used in this investigation. Th...

Purpose Developing countries are now fully aware of the importance of the manufacturing sector as a key factor of growth and transformation of their economy. Improved technology and method of manufacturing have produced quality products at reduced cost and this has advanced development. The study uses experimental methods based on orthogonal cuttin...

The blanketlike covering of the earth's-near-surface-air by greenhouse gases which has made the planet to be habitable by living things, has been threatened in recent times by technological and other pollutants. British Broadcasting Corporation (BBC) statement of 6th October 2008, that the protective ozone layer is being depleted at the rate of 6%...

Gari is a popular staple food in Nigeria. It is got from the dry frying of dewatered cassava pulp. Cassava is a plant which originated from South America but is now grown in most of the African countries. The Nigerian variety grows to a height of 0.6 to 2m. The root is the most useful part of the plant. It is about 35cm in length with a diameter of...

The needs in the highly challenging environment for organizational competitiveness with respect to cost, quality services and on-time deliveries through optimum machine functionality, guaranteed long-term stability, increases in productivity and system reliability have contributed to new interest in maintenance planning and assessment. The research...

Mechanical failure of component parts as well as in build up structures can be prevented if proper quality control is carried out at point of component's manufacture. Engineers are known to analyze samples from which accurate predictions are made about the properties of the materials that are produced for the purpose of component and structural pro...

As a result of rapid advances in modernization schemes during the past four decades, industrial maintenance has become so sophisticated that trained personnel are necessary. Maintenance, an aspect of the engineering discipline, is rooted in engineering practice and is so important for the smooth running survival of any industrial set up. Discussion...
