Development and Testing of Asbestos Free Brake Lining Material
DEVELOPMENT AND TESTING OF ASBESTOS FREE BRAKE LINING MATERIAL

INTRODUCTION

The friction material in the automotive brake system has been considered as one of the key components for overall performance of a vehicle. This is because it plays crucial roles in various aspects of the brake performance such as a stopping distance, pedal feel, counter disk wear and brake induced vibrations. A great deal of effort has been given to improve the performance of the friction material and multiphase composites have been used as a brake friction material from the early stage of vehicle development since a monolithic material has never been successful for commercial brake friction materials.
More than 10 ingredients have been used to produce commercial brake friction materials, expecting that each ingredient provides beneficial roles for brake performance under different braking conditions. Brake pads typically comprise the following sub-components a) Frictional additives, which determine the frictional properties of the brake pads and comprise a mixture of abrasives and lubricants b) Fillers, which reduce the cost and improve the manufacturability of the brake pads; c) a binder, which holds components of a brake pad together d) reinforcing fibers, which provide mechanical strength.

Before the ban on usage of asbestos in brake linings was imposed in 1989, Asbestos was the most preferred filler material as it is thermally stable upto 5000C, helps regenerate friction surface during use, insulates thermally, strong and flexible and mostly, it is available cheap. Since the ban on asbestos, researchers have struggled to come up with an equally efficient alternative. Barites, mica and cashew dust are amongst some of the materials that have been considered for use as fillers.

    I would have to disagree about banning all asbestos because some asbestos fibres are harmless. People and workers have more risk of developing a disease in 20 to 40 years if their handling the asbestos fibres and inhaling the fibres. Asbestos fibres, like chrysotile fibres, aren't harmful to people until countless fibres are discharged in the air. Now, asbestos fibres are made in a solid matter that doesn't cause it to spread into the air. Chrysotile is one fibre that is less harmless compared to amphiboles.…

    Brakes are the most important safety feature on any vehicle and play a huge role in all aspects of the car. Since the early 1900’s, there have been many different kinds of brakes invented and manufactured. There are two types of brakes that stuck around to still be used today, they are referred to as drum and disk brakes. Sensors and technology have improved the way brakes are made and functioned today. Although these advances are very beneficial to car buyers, it can become expensive to people who aren’t familiar with changing the brakes themselves. Components of most vehicles brakes are very simple and they are easy to understand for most people. If they are not changed properly, it could lead to negative results.…

    Rub on wax was also consistent throughout this experiment, demonstrating at the three different heights that it was faster than all waxes except one, hot wax. Paste wax was repetitive at each of the heights tested routinely following hot wax followed by rub on wax for the entire experiment. Spray on wax increased the amount of friction the skis had. In two out of three trials the control, non-waxed base or control, provided better results than the spray on wax did. In some cases spray on wax could help a skier’s friction only if it is applied on top another wax. That is its main purpose, to be applied as a booster if a skier didn’t have enough time to freshen the wax on the skis. Overall, hot was demonstrated it demonstrated the friction of a skier most…

    In lab 4.1, the factor of friction came from the different surfaces. The surface that an object is in contact is crucial to the movement of that object. In lab 4.2, the data that was acquired showed that the weight and mass of an object affects friction along with the surface type. In lab 4.3, the surface area in an object does not matter, but the weight and mass of the object counts. Throughout these three labs, the lesson that was learned is that friction is controlled by the weight and mass of an object in contact with a…

    Asbestos exposure is clearly defined as inhaling and swallowing tiny particles and fibers. The particles in question become airborne when asbestos are broken up or disturbed. When asbestos fibers are inhaled or swallowed, they may lodge themselves within the lining around the lungs, abdominal cavity or heart. These particles can build up over many years without any symptoms whatsoever.…
