Investigation of The Effect of Solid Lubricant Particle Sizes on Friction and Wear Properties in Friction Composites: An Experimental Case Study with Graphite

Sugözü, İlker | Sugözü, Banu

Friction composites consist of many materials with various properties. Solid lubricant is one of these materials. The task of the solid lubricant in the compo-site is to protect the counter surfaces against wear and to reduce noise and vibra-tion. Typical solid lubricants used in the friction composite are graphite, antimo-ny trisulfide, molybdenum disulfide, copper sulfide, etc. The selection suitable solid lubricants for better braking performance is an important issue, as solid lubricants may decompose at high temperatures, leading to undesirable results. The particle size of the solid lubricant used is at least as important as itself. In this study, the effect of micro and nanoparticle-sized graphite on friction and wear behavior of friction composites was investigated experimentally. ...

The effect of ulexite to the tribological properties of brake lining materials

Sugözü, İlker | Sugözü, Banu

Recently, different brake pads have started to be investigated in brake friction industry by replacing the asbestos with new materials. This paper presents the role of Ulexite on friction assessment and screening Test of newly formulated brake pads. Friction coefficient, specific wear ratio, and scanning electron microscope SEM for friction surfaces were examined to assess the performance of brake pads. From the results, they concluded that the friction material containing Ulexite improved friction stability and fade resistance. Further, for heat treated samples they claimed a higher and stable friction coefficient

The Effect of Wearing Brake Lining Surface on Braking Performance

Sugözü, İlker | Sugözü, Banu

After braking, different wear types and micro-macro gaps occur on the brake lining surface. This situation varies depending on the amount of binder, friction modifier, reinforcement, lubricant and filler materials used in the brake lining content and braking conditions. In this study, the effect of brake lining surface morphology, which is worn after braking, on the tribological properties of the brake lining was investigated. In this context, the wearing surfaces of the brake lining after braking were examined. It has been observed that the braking performance increases depending on the rate of wear types seen on the brake lining surface.

Investigation of the Use of a New Binder Material in Automotive Brake Pad

Sugözü, Banu | Sugözü, İlker

In this study, the usability of waste banana peel and banana tree bark with a fibrous structure as binders was investigated experimentally. Ac-cordingly, the amount of fiber, friction regulator, filler, abrasive and sol-id lubricant is fixed, and three different brake pad samples were pro-duced by adding 10% banana peel and 10% banana tree bark powders by reducing the amount of phenolic resin. Production was carried out by conventional dry mixing method and powder metallurgy method. For this, firstly a homogeneous mixture of all ingredients is provided. The mixture transferred to the mold was pressed at room temperature firstly. Samples obtained as the first form were subjected to hot pressing in the mold again. Thus, the ability of the resin to hold all the materials together has become a...

The Effect of Braking Pressure on Friction and Wear Properties of Brake Lining

Sugözü, İlker | Sugözü, Banu

The brake system is used to slow down or stop the vehicle speed. The brake lining is the most important part of the brake system, which is used to slow down or stop the vehicle by converting friction energy into heat energy. The pressure applied to the linings in the vehicle brake system is an important factor for the lining performance. The brake lining exhibits different properties depending on the pressure applied during braking and the brake lining content. In this study, friction coefficient and wear properties of brake linings at braking pressures of 5, 10 and 15 bar were investigated. The pressure increase increased the disc surface temperature and the wear amount of brake lining.
