Sürtünme aşınma dayanımı amaçlı polimerik kompozit malzemelerin analizi

This research is about manufactured brake pads from a polymeric composite material composed of domestic materials available in the market and cheaper. The unsaturated polyester is used as the basic material for the prepared samples. Add the fillers such as the Styrene Butadiene Rubber (SBR) and Montmorolonite Clay and the other filler that is cheap and available in the market to prepare the samples. In additions, the Kevlar fibers, the nylon, and the steel is used as reinforcing materials for these samples for reinforcement percent from 10%-25% to improvement of mechanical properties. The samples were prepared from these materials and tested the mechanical and physical feature of these sample; and the compared the test result with the commercial pads available in the market. The hardness test of Shore D, resistance of Impact, compression, resistance of Wear and thermal conductivity tests have been carried out. After doing above mentioned tests on the prepared samples, it is found that most of the feature of the prepared sample and that which, reinforced by fibers are better than the feature of commercial pads available in the market. The samples that are numbered 7,9,10 and 11 are the most suitable ones for making pads since the test results of mechanical features were much better than the features of the commercial brake pads.
