April 10. 2017 - The aim of this work is to study the friction and wear of polyester as flooring materials filled by recycled rubber. The test rig, used in the experiments was top scratching tester equipped with an indenter to produce a scratch on a flat surface with a single pass. The tested material is polyester filled by different contents of recycled rubber 5, 10, 15, 20 and 25 % with different particle size. Test results show that, increase rubber content show significant increasing in friction coefficient for polyester composite. The maximum value of friction coefficient (1.75) for polyester composite observed at specimens contain 25 % rubber. While the minimum friction value (0.18) observed at pure polyester specimens. Increasing particle size of rubber shows significant increase in wear of polyester composite.
