Abstract:
The invention relates to brake pad comprising a backing plate and friction layer, compacted together said backing plate being made of a composite having graphite ≤2, copper powder ≤4, nickel powder ≤5, chromium powder (ferrochrome) ≤ 5, phosphorous (ferrophosphorus) ≤ 1, SiC ≤5, Iron powder and said friction layer being made of a composite having iron powder 65-85wt% copper powder 3-12 wt % ferroalloys 2-10 wt% ceramics≤ 8 wt%, lubricants ≤12 wt%, others ≤10 wt%. A process for manufacturing brake pads comprising the steps of providing a powder mixture for the backing plate of the brake plate of the brake pad comprising iron powder and natural crystalline graphite copper powder, nickel, chromium powder, phosphorous powder and silicon carbide, providing a powder mixture for the friction layer of the brake pad comprising iron powder, copper powder, ferroalloys, ceramics, lubricants and other additives: filling a suitably designed die with a predetermined quantity of the powder mixture for backing plate, followed by the powder for the friction layer, to form two consecutive layers, subjecting the powder layers to pressing under high pressure to form a compact, ejecting the compact, heating the compact to obtain a perform followed by, subjecting the perform to forging to provide the brake pad. 

 
THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
