Low-impact friction materials for brake pads
State-of-the-art friction materials for applications in disc brake systems are constituted by composite materials, specifically formulated to ensure proper friction and wear performances, under the sliding contact conditions of braking events. The bases of typical friction compound formulations …

Wear of aluminium MMCs against automobile friction materials
… been worn against three different automobile friction linings (brake pads). Two of the friction linings are commonly used against cast iron brake rotors while the third has been formulated for use against aluminium MMC brake rotors. Wear processes at the interfaces of the specific rotor - pad …

Molecular Dynamics Study of Characterization in Metal-Free Friction Materials
<p>Metallic friction materials currently used in industry may adversely impact the environment. Substitutions for metals in friction materials, on the other hand, can introduce operational safety issues and other unforeseeable issues such as thermal-mechanical instabilities and insufficient …

Towards Sustainable Braking: Effects of Alternative Ingredients on the Tribological Properties of Friction Materials
… on improving the sustainability aspects of brake friction materials. This was done by following two different approaches, both of which involved the use of alternative ingredients in the friction material composition. The new ingredients were chosen based on their properties while also considering …

Automobile friction materials: a test instrument and technique for determining dynamic mechanical properties in relation to brake squeal
… using moulded organic disc pads. Moulded organic friction materials are complex composites and due to this complexity it was thought that they are unlikely to be of uniform composition. Variation in composition would under certain conditions of the braking system, cause slight changes in its …

Finite Element Analysis of Thermal-Mechanical Instabilities in Nonmetallic Friction Composite Material
… thermal buckling.</p> <p>Alternate non-metallic friction material and the effect of anisotropy in friction materials was also investigated to determine the limits of brakes and clutches at which thermal-mechanical instability can occur. Carbon-carbon silicon carbide as a replacement for metallic …
