Analysis of Brake-Pad Friction Material Formulation

In the technologically advanced era that we currently live in, there is a growing demand for cheaper and more durable materials for a variety of purposes. The most important safety feature of an automobile is its braking system. The ability of brakes is to provide safe and repeatable stopping, which is related to safety of automobiles and human. Automotive friction materials are multi component composites in which binder, fibers, fillers and property modifier all plays important role. The presented research work investigates/explore the influence of mineral fibrous reinforcement like lapinus fiber and wollastonite fiber on the physical, mechanical and wear performance of friction materials. The composites formed have common master batch of straight phenolic organic resin, barite, Kevlar and graphite. The designed formulations are fabricated as per the standard procedure and the moulding processing conditions adopted according to industrial standard. The samples are then characterized for their physical, mechanical and sliding wear properties. The physical and mechanical properties of such friction composites have been found to be well within the standard industrial norms. The specific wear rate generally increases with the increase in applied load and sliding speed for all compositions found to increase with increase in wollastonite
