The present study aimed to assess the effect of replacing copper as a multi-functional ingredient in the brake pad material with potassium titanate platelet (PTP) and a particular type of ceramic fiber (CF) copper-free composite. Chase dynamometer tests were conducted to compare a brake padchr('39')s tribological behavior when PTP and CF are added to the composition with that of the copper-bear...

Electric vehicles (EVs) are heavily promoted as beneficial for climate and health. In most studies, it is assumed that EVs contribution to urban air pollution zero due no tailpipe emissions, ignoring the of non-exhaust particles (brake, tire road wear), which unregulated in EU. This study Stockholm, Sweden, aims 1) assess how a future vehicle fleet impacts concentrations size less than 2.5 μm (...

Compliance with air quality standards requires control of source emissions: fine exhaust particles are already subject to regulation but vehicle fleets increase whilst the non-exhaust emissions are totally uncontrolled. Emission inventories are scarce despite their suitability for researchers and regulating agencies for managing air quality and PM reduction measures. Only few countries in Europ...

Vehicle braking system is considered as one of the most fundamental safety-critical systems in modern vehicles as its main purpose is to stop or decelerate the vehicle. The frictional heat generated during braking application can cause numerous negative effects on the brake assembly such as brake fade, premature wear, thermal cracks and disc thickness variation (DTV). In the past, surface rough...

The spatial distribution of potentially toxic elements in land near a heavily loaded highway the West Attica region (Greece) is discussed. This study aimed to investigate extent soil contamination with trace on margin highways. concentration thirty-five topsoil, car ash, and road sediment bulk samples was determined. Statistical analysis applied for evaluating geochemical dispersion examined el...

Abstract Abrasives, such as oxides of alumina (Al), silica (Si), zirconia (Zr), chromium (Cr) etc., are added to raise the friction level and also remove glaze on disc so that surface will be rejuvenated continuously during braking contribute maintain desired level. However, these inorganic particles have less adhesion with resin/binder hence easily dug out wearing process contributing higher w...
