ABSTRACT
Development of an abrasive sandpaper using Africa star apple shell and other composite materials was investigated with a view to replace the use of asbestos which is harmful to human health. The samples were sieved into two particle sizes of 100μm and 125μm, A total of four tests were carried out on the sample for investigation of mechanical properties namely; compressivetest, porosity, coefficient of friction, and wear rate. The results showed that samples with 100μm gave the best mechanical properties. From the analysis of the experiment conducted, it was revealed that the co-efficient of friction of the pad material ranged from 0.3-0.45, compressive strength of 80-105KN, density of 1.8-2 g/(cm)^3, porosity of 3-5.07% and wear rate of 1.0-2.5(g/9cm0^3) ×10^2 as compared to the conventional brake pad material that has density 1.83 g(/cm)^3, porosity of 5.07% and coefficient of friction with range 0.3-0.45. These results are in agreement with those of existing works produced. It is therefore concluded that this composite material can be used for sand paper production. The result obtained were compared to other Agro waste composite which shows that the Africa states apple seed composite has some considerable mechanical properties as to other agro waste by product that were reinforced with epoxy matrix and has been used in some engineering applications.
