Industrial brake lining materials are composite with complex formulations consisting of multiple constituents. Resulting from the fabrication process, morphology and distribution constituents have significant influences on future properties braking performance. In this study, an in-depth analysis ranging microscale to macroscale was performed assess relationships between microstructure, mechanical performance industrial material formulated for heavy vehicles. It observed that manufacturing...

AbstractThe manufacturing process of organic friction material used for braking applications is importance with regard to their properties and performance. This article deals a manufactured according two different hot molding conditions. An original analysis polymerization the phenolic resin matrix led choice temperature duration process. Two materials were developed, changing these dependent parameters, wear behaviors investigated various thermal severities sliding The conductivity was also...

Depth of pits that propagate during a pitting corrosion process is an important characteristic the damage steels; greater depth, more dramatic damage. For evident reasons safety and reliability industrial installations, statistical procedures must be constructed to assess maximum pit depth perform proper maintenance from limited inspection data.This paper outlines new methodology predict accurately extreme value related localized independently nature unknown parent distribution experimental...
