“…The outcome reveals that wear rate reduced with the growth in wt% of the resin. Olabisi et al [37] analysed the wear rate for the pulverized cocoa beans shell epoxy composite and obtained the wear rate of 3.934 mg/m. Yawas et al [38] studied the wear rate of periwinkle shell filled composite and concluded that the wear rate reduced as the corresponding powder size reduced.…”

Wear rate appraisals are currently indispensable on agro-waste filled composites for brake pads as they predict the expected lifespan of the materials. However, existing wear rate models are inaccurate as predictions omit the inflationary cost of the materials. In this paper, the idea is to account for the inflationary cost of the materials and adjust that into a pseudo wear rate model. The wear rate of agro-waste fillers in an organic matrix to create brake pads under dry sliding wear experiments was considered. Five composite specimens were fabricated in cylindrical specimen height of 14.5 mm and varying diameters of 8, 10, 12 and 15.5 mm and the material wear loss was measured. The 8, 10 and 12 mm diameter specimens revealed that the composite with the best and worst wear resistance were the wear rates of 0.6, 1.4, 1.73 mm3/Nm, and 3.07, 3.54, 4.19 mm3/Nm, respectively. The 15.5 mm diameter specimen showed lower wear rates of 2.13 and 2.14 and 1.56 mm3/Nm than commercial brake pad’s 2.58 mm3/Nm. The pseudo wear rate model predicts the impact of the independent variable i.e. inflationary cost, opportunity cost, time, and sample size. The utility of this effort is to assist the composite manufacturers to take cost-effective decisions and design optimisation can be accomplished to lower the cost of composite products.

“…The wear rate of commercial conventional asbestos based brake pad is 3.8 x 10 -6 g/m (Olabisi et al, 2016) while the range of wear rate of all the composites obtained in this study is (1.909 -2.705) x 10 -6 g/m. This is much lower than that of asbestos based conventional brake pad and is an indication that the composites have the potential of better performance when used as brake pads.…”

Production of friction particulate ceramic matrix composites (PCMCs) by powder metallurgy method was carried out using iron 105 μm millscale, 50 μm silica sand, 80 μm magnesia and 53 μm bentonite clay as input materials. Different formulation of the blend of these materials were prepared and the composites were produced. Microstructural, frictional, thermal and wear characterisation were determined using standardised methods. The ceramic composites exhibited very good properties in terms of thermal stability (heat resistance), coefficient of friction (COF) and resistance to wear. The specific values of these properties exhibited by sample D having 12 wt. % iron millscale addition in terms of high resistance to thermal decomposition in the temperature region (0 – 1600 0 C) indicating thermal stability, appreciable high COF (0.59) and very low wear rate of 1.9093 x 10-6 g/m are desirable. The uniform dispersion of the particles as observed in the microstructure and strong bonding/adhesion contributed to the enhancement of the properties. These results are indication that the composite is very suitable for application in areas where high resistance to thermal stress and abrasive wear are required such as the brake assembly of automobiles, specifically the brake pads.

“…The agro-waste based inoculant raw material (CBS) was obtained separately (Figure 1), well sun-dried, and cleaned to remove impurities. It was then crushed, and pulverized into a fine powder and sieved using different sieves of 150, 225, and 300microns aperture respectively [16]. The samples were sand cast in the foundry workshop.…”
