The performance characteristics of the system (e.g. chemical composition, microstructure, wear rate, and friction coefficient) are presented and discussed.…show more content…
Other categories have also been cited such as metallic and low-metallic but these may be variations on the semi-metallic pad.1 However, all auto repair shops and parts stores contacted offered only organic or semi-metallic brake pads. The different formulations have varying wear rates, braking properties, and noise levels. Semi- metallic brake pads are visibly different from organics. Semi-metallic pads are a darker color with visible metallic fibers and have a rough texture. Organic pads are a lighter shade of gray and have a smoother texture. Organic formulations often contain polymers such as Kevlar, resins, and sometimes asbestos fibers. Organic brake pads may also contain copper. In the past, asbestos was used extensively in organic formulations before it was discovered that breathing dust containing asbestos fibers can cause serious bodily harm. Today, although use of asbestos is still legal, manufacturers are generally moving towards non-asbestos organic formulations for safety reasons. Semimetallic generally refers to the presence of iron and steel in the formulation. Semi metallic brake pads are composed of finely powdered iron or copper, graphite, and lesser amounts of inorganic fillers and friction modifiers. Manufacturers have voluntarily phased out lead in brake pad formulations to protect human health. In the (Table 1)and (Figure 3) we see the chemical composition of friction pad material (EL-Tayeb, N. and Liew, K.
