COMPARATIVE BENCH TESTS OF NEW GENERATION POLYMER RESIN BONDING FRICTION BRAKES
Journal Title: Tribologia - Year 2009, Vol 224, Issue 2
Abstract
Prototype friction brakes with lining made of modified resin bonding were the subject of the studies. The idea of polymer modification in a tribochemical way, leading to a decrease of its toughness, resulted in grafting of 5-30 wt. % of elastomer. Resin composites: The following elastomers were tried as modifiers: butadiene-acrylonitrile rubber (conventional Or hydrogenated), acrylic rubber, chloroprene rubber, silicone rubber or polysilsesquioxanes (POSS) with methyl or phenyl functional groups. Bench tests on front axle braking system of FIAT „Seicento” having brake blocks containing new polymer bonding, were run on an inert mass stand at Braking System Laboratory of Automotive Industry Institute (PIMOT). Efficiency of braking under „cold conditions” as well as its speed sensitivity, according to p. 3 of the Regulation EKG ONZ no. 90 were tested. The results obtained were compared to commercial brake blocks: Ferit I/D 458 FG and Fers-TC, used as references. Tribological properties of the blocks were tested using the Krauss test, according to p. 8 of the Regulation EKG ONZ no. 90 were additionally determined.<br/><br/>
