CAR BRAKE PADS AND ECOLOGY
Keywords:
brake pads, wear particles, air pollutionAbstract
The work shows that one of the most polluting sources of atmospheric air is the brake pads of modern cars and similar vehicles, which, when worn, emit dispersed and ultrafine particles in the air, classified as PM10 and PM2.5; it has now been proven that they cause many diseases in humans. Georgian scientists have developed a new generation of environmentally friendly, wear-resistant friction materials for brake pads and their properties have been studied together with Swedish scientists. Comparison of the developed, non-metallic (LM) and non-asbestos (NAO) with those friction materials that are common in European and USA markets, showed the superiority of our developed materials. During their wear process, much less wear particles are produced in the air and less number of elements are observed in the wear products / <6 / compared to foreign analogues /> 7-10 /.
