Investigation on hardness and impact properties of different type of commercial brake pads / Nor Azlina Adnan

In spite of tremendous progress that has been made in the discipline of material science and engineering within the past few year, there still remain technological challenges, including the development of even more sophisticated and specialized materials in friction material or known as brake pad material. These materials have been used due to its desirable mechanical properties and in the mean time with economical consideration. For these reason the mechanical properties maybe considered the most important of all physical and chemical properties of friction material for most application. This project is about the investigation of the mechanical properties after subjected to the hardness and impact test. The main objectives of this study are to study the impact and hardness test on commercial brake pad and also determine the mechanical properties of the brake pad. All the samples used are the commercial brake pad available in market. The compounds of the samples were determined by using X-ray Diffractrometer. The hardenability of the commercial brake pad was investigated by using Rockwell test according to MS 474. While the Dynatub machine are used to get the data for the impact test.
