Investigation of Friction Performance Related to Use of Pinus Nigra Cone Powder in Automotive Brake Pads

Ilker Sugozu


This paper aims to investigation wear and friction properties of a new developed brake lining material, and the effect of pinus nigra cone dust on its performance. Hence, three different material samples were produced, examined and analyzed. The tribological properties of the first (without pinus nigra cone dust), second (containing 8% pinus nigra cone powder) and third (containing 12% pinus nigra cone powder) sample types were determined using pin-on disc type tester. Coefficient of friction, wear (mass loss) and friction surfaces were studied to evaluate the performance of the three brake linings. The friction surfaces of the brake linings were examined by scanning electron microscopy (SEM). Hardness tests of the samples were made on the Brinell tester. The densities of the samples were determined by Archimed scale method. The results indicated that the brake linings containing pinus nigra cone powder exhibited the better friction performance.
