Abstract
The quest for quality brake pads employed both in civil and military aircrafts to
ensure safety continues to attract attention. Mill scale reinforced silica-magnesia
hybrid composite represents a potential new generation of high performance
material that exhibits numerous advantages over conventional friction/ceramic
materials. In this study, physical characterization of selected friction materials using
both X-ray fluorescence (XRF) and X-ray diffraction (XRD) techniques was carried out
in order to identify relevant potent compounds in them. Silica and magnesia were
chosen as hybrid matrix reinforced by iron mill scale. It was found that the selected
materials contain relevant potent friction/thermal compounds up to 68.8 % FeO,
98.9 % and 98.8 % for SiO2 and MgO respectively. Thus, the synthesis of these
materials through optimum formulations represents a boost to the production of
high quality brake pads for aircrafts.
