The effects of porosity in friction performance of brake pad using waste tire dust

2015

SbstractThis research is focused on the effect of porosity on the friction-wear properties of automotive brake pads. Waste Tire Dust (WTD) was used as a new friction material in brake pads. Newly formulated brake pad materials with five different components have been produced by conventional techniques. In the experimental studies, the change of the friction coefficient, the temperature of the friction surface, the specific wear rate, and the hardness, density and porosity were measured. In addition, the micro-structural characterizations of brake pads are determined using Scanning Electron Microscopy (SEM). The mean coefficient of friction, porosity and specific wear are increased due to a WTD rate increases, on the other hand, hardness and density are decreased. As a result, WTD can be considered as an alternative to revalorize this kind of waste products in the brake pads and the amount of porosity of the brake pad affected the friction coefficient and wear behavior of the pad.

“…The following procedure is followed to prepare brake pad. They are as follows, mixing of friction materials, production of pre-forms, shotblast of baking plate, curing and machining [14][15][16]. All the ingredients were weighed using an analytical balance instrument to an accuracy of 0.1 g. The ingredients are mixed using a blender (electron EBR 100) for 16 min at 4000 rpm at room temperature (30°C).…”

The effect of palm fiber on properties of automotive brake composite materials is analyzed. The test procedure followed is JASO C 406, which is for passenger car pads. Tribological properties of three brake pads (6 PF, 8 PF and 10 PF) were tested on full-scale inertia dynamometer for various performance parameters such as pressure-speed sensitivity (effectiveness studies) and Temperature sensitivity (fade and recovery behaviour). A pad undergoes all the testing parameters and maintains its low temperature rise in the disc for three pressure sensitivity and two temperature sensitivity tests. By increasing palm fiber content, hardness, heat swell and specific gravity increases, and also porosity and loss on ignition decreases. Test has been conducted using scanning electron microscope to analyse the all three specimens to evaluate the contact plateaus and wear debris during braking. 8% of palm fiber content in brake pad was found to be superior to 6 PF and 10 PF in most of the important tribological properties.

This work presents the function of biobased ingredients (palm fiber) as reinforcement in brake pad materials. Reinforcement in brake lining improvise wear stability, wear resistance and friction optimization under a dynamic set of operating variables such as braking force, sliding speed, braking duration and braking temperature. The effect of palm fiber on physical, mechanical and tribological properties of brake pad composite is evaluated. The percentage of palm fiber is gradually increased from 2% to 12% at an interval of 2% as an alternate of rockwool fiber by varying the pressure and speed in a pin on disc tribometer. By increasing the pressure, 8% and 10% shows high friction stability at all speeds. The results show that the raise in the palm fiber quantity increases the hardness, specific gravity and heat swell and the properties, loss on ignition and porosity decreases. The SEM descriptions of the composite indicated that the smaller micro voids occurred in the sample having low palm fiber. Weight gain in the composites were also observed by exposing them in salt water, water and oil.
