“…The good distribution of the particles in the microstructure as illustrated in Figures 4 -7 and their adhesion must have been responsible for enhancement of the shear strength of the samples. This agreed with the postulation that strong interfacial bonding between the filler and matrix increases the shear strength [9,22]. Weak interfacial bonding of the particles could be responsible for the decrease in the shear strength exhibited by sample E having more than 12 wt.…”

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, water absorption, and mechanical characterisation were determined using standardised methods. The ceramic composites exhibited very good properties in terms of density, water absorption, hardness, compressive strength, shear strength and impact energy. The specific values of these properties exhibited by sample D in terms of density (1.87 g/cm 3 ), water absorption (0.3 %) indicating reduced pores/voids, hardness (147.09 BHN), compressive strength (156.45 MPa), shear strength (5.97 MPa) and impact energy (7.62 J) 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 compared favourably well with that of conventional automobiles brake pads which is an indication that the composites are very suitable for application as automobiles brake pads.

“…The increase in the weight fraction of FeO particles (metal phase) confers on the samples the level of plasticity sufficient to absorb energy, thereby increasing the impact energy. Invariably, increasing the weight fraction of iron millscale particles (FeO) led to an increase in elasticity within the composite core, thereby increasing its toughness [21].…”

The quest for quality brake pads for use in aircrafts and automobiles to ensure effectiveness and safety continues to attract attention. Hence, this study was carried out as part of the global efforts at tackling the problem of the low durability of these friction materials. An iron millscale (IMS) particle reinforced ceramic matrix composite (CMC) was developed by the powder metallurgy method and characterised. The IMS particle addition varied from 5-30 wt.% in each CMC produced at different particle size distributions (106-250 m) using silica (SiO 2 ), magnesia (MgO), and sodium bentonite as matrices. On the basis of the close correlation between structure and property, the CMCs were subjected to physical, mechanical, and microstructural characterisation using X-ray Fluorescence (XRF), X-ray Diffraction (XRD), and Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM/EDS). The composite exhibits desirable physical and mechanical properties in terms of density (2.97 g/cm 3 ), porosity (1.24%), linear shrinkage (1.39%), impact energy (43.07 J), and compressive strength (114.17 MN/m 2 ). These values compare very well with the values of brake pads obtained in previous studies and conventional/commercial brake pads, indicating a potential for effective performance in service.
