Main Performance Characteristics for Brake Composite Friction Materials
Any quality brake pad and brake lining shall exhibit many performance requirements as:
1- Appropriate coefficient of friction (COF) depending on the final usage,
2- Stable coefficient of friction under various operating e.g. braking pressure, speed, temperature, and environmental conditions,
3- Good thermal stability and high mechanical strength,
4- Low wear rate and high durability,
5- Minimized noise, squeal and vibration during braking
6- Low detrimental effects to counter-face like disc rotor,
Interestingly, all above performance requirements are basically maintained by the performance characteristics of composite friction elements themselves. Therefore, composite friction materials play vital role in frictional braking system.

New Classes of Composite Friction Material Formulations
In-line with current technologies of brake friction material formulations used by internationally recognized automotive brake pad manufacturers, Pak-Fan Composite Sharif is proud to manufacture friction material compounds based on the latest formulation technology which include Low Steel (LS) NAO and Ceramic formulations. The main specific feature of LS NAO formulations is that this kind of friction materials contains low content of steel wool (less than 20 wt%) with no other ferrous components. In ceramic formulations, steel wool is totally replaced with organic fibers like aramid fiber and inorganic fibers like ceramic fibers, so this kind of formulations contains no ferrous metal components and no steel wool. The LS NAO formulations are mostly used for the automotive brake pads in European countries where stopping from high speed is actually usual; while brake pads and brake linings based on ceramic formulations are mostly preferred in Japan and North America.

Innovation in Friction Materials Formulations
Composite friction materials are composed of at least 15 different ingredients. In this respect, formulating a friction compound is indeed the selection of right ingredients with appropriate composition for a specific composite friction material with an intended performance. Actually, development of a new formulation with an intended performance is a rigorous and lengthy task requiring a full expertise in the field of friction composite formulation, which is indeed core competence of Pak-Fan Composite Sharif. Such expertise of Pak-Fan Composite Sharif relies basically on its extensive researches on the field of composite friction formulations for almost two decades. In practice, development of a commercial friction compound for a specified application begins with design of formulation followed by extensive laboratory testing to field tests on real cars which almost takes from few months to even few years. At Pak-Fan Composite Sharif, innovation is placed in the heart of the development of any commercial product. In this regard, our goal is to update our current commercial compounds with new or even much refined raw materials as well as design and manufacture of new products with totally new formulations for a wide range of applications from brake pads in light vehicles to brake composite friction materials in heavy duty systems. Developing friction compounds based on nanotechnology and extension of green friction formulations are our current trends in Pak-Fan Composite Sharif.

Environmental Concerns
Presence of harmful ingredients in the conventional composite friction materials and generation of wear debris during braking and emission of such wear debris in environment are two main concerns related to frictional braking system. Our current friction compounds are free of many prohibited raw materials such as asbestos fiber, lead, antimony and etc. Meanwhile copper is excluded in some of our compounds or kept low, less than 5 wt%, as some regulations expected. Our current effort is to produce copper-free ceramic friction compound
and is to seek green materials for reducing detrimental effects of wear debris which are known as basic source of environmental pollution.
