Abstract
This study is focused on development of an eco-friendly abrasive sandpaper using walnut shell (WS) with the binding effect of epoxy resin on WS, iron oxide and silica, calcium carbonate (CaCO3) and pulverized graphite. The method of mixing and mould compression using a hydraulic press matrix composite with five varying composition was used. The compositions were made by varying the weight of WS, epoxy resin with that of iron oxide and silica, calcium carbonate and pulverized graphite were left constant expressed in percentage weight The abrasive properties investigated were density, compressive strength and wear resistance and water and oil absorption rate. The results reveals obtained that the density, wear resistance rate and compressive strength of the tested composition decreases with increasing WS content despite the fact the rate water absorption increases with increasing WS. The result of obtained reveals that WS can be utilized in the production of abrasive sandpaper
Highlights
Rapid growth in industrialization has necessitated the need for improvement of materials properties which includes and not limited to lower cost, density, stiffness, strength and must be sustainable
A very limited research papers were found on composite made from walnut reinforcement in the present work walnut shell particle based composite is been produced with the aim of investigating its potential as possible substitute for asbestos in making of abrasive sandpaper
From the observed results there is decreased in density of the samples with increase walnut shell (WS) content
Summary
Rapid growth in industrialization has necessitated the need for improvement of materials properties which includes and not limited to lower cost, density, stiffness, strength and must be sustainable. A lot of efforts have been put by different researchers in recent years to exploit locally sourced materials in the development, formulation, construction, manufacture of goods for instance building materials, tools and equipment, design and manufacturing etc. The application of wastes will be cost effective, and might as well bring about environmental control and improve foreign exchange (Aku et al, 2012).The necessity to utilize this unlimited capacity in transforming wastes into wood or metal work tool identified as abrasive sandpaper. The convenience of agricultural wastes in manufacturing sector is cost effective but helps in the control of environmental pollution (Oyelaran et al, 2015). Ample industrial and agricultural wastes are produced in developing nations, they can be converted as possible material or substitute in the production of parts and components
