Abstract
This 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.
Highlights
Automotive friction materials have been formulated preservation
Nowadays, formulated automotive when developing brake materials to fulfill requirements friction materials are generally multi-component systems such as, a stable friction coefficient and a lower wear rate that comprise more than 10 components, in order to achieve at various operating speeds, pressures, temperatures, and the desired friction properties[2,3]
The results revealed that Waste Tire Dust (WTD) can be used for friction materials in the brake lining pad
Summary
Automotive friction materials have been formulated preservation. Nowadays, formulated automotive when developing brake materials to fulfill requirements friction materials are generally multi-component systems such as, a stable friction coefficient and a lower wear rate that comprise more than 10 components, in order to achieve at various operating speeds, pressures, temperatures, and the desired friction properties[2,3]. S S S material is a multi-component polymer matrix composite with a formulation often developed empirically[4]. Brake pads used in automotive brakes are generally made of many components. These are classified into four major categories binder, fibers, friction modifiers and fillers all of which are based on the major function they perform apart from controlling
