Synergistic effect of red mud-iron sulfide particles on fade-recovery characteristics of non-asbestos organic brake friction composites

The Purpose of this work is to develop a niobium based metal matrix alloy through sintering based powder metallurgy technique. The 2, 4 and 6 weight percentage of Titanium Carbide (TiC) is added to the alloy. Various material properties such as hardness, tensile strength, impact strength and density are measured after the addition of TiC particle. The characterization, microstructure and particle size of the developed metal matrix are learnt through Scanning Electron Microscope (SEM) and Energy

“…The conventional methods were used to develop the brake pads, namely mixing in plough shear mixer having three chopper and one shovel rotating in the speed of 2800 rpm and 140 rpm respectively for 20 min, the sequence of mixing followed was fibers for 6 min, then fillers and frictional modifiers for 10 min and finally binders for 4 min. Followed by curing in hydraulic operated compression molding machine at 145°C for 8 min with five intermittent breathings having pressure of 13 MPa, followed by post-curing in hot air oven for 5.5 h by following step baking process from 140°C-160°C for 3 h At 160°C for 2 h; 160°C-165°C for 0.5 h. Finally the finishing was done to remove the unwanted resinous layer and make the pad to the required thickness using belt grinder [17,18]. The developed brake pads are given in figure 1(a).…”

Natural fibers are widely used in the various lightweight and medium load applications due to their vital advantages. Cyperus pangorei is abundantly found on the river banks. The current study deals with the usage of Cyperus pangorei fibers that were retted using a manual retting process in the brake pad formulation. The fibers retted were treated with benzoyl chloride to enhance adhesion characteristics. The benzoyl chloride treated and untreated Cyperus pangorei fibers were used in the development of brake pads with other ingredients constant as per industrial practice. The developed brake pads were analyzed for its physical, chemical, thermal and mechanical properties as per industrial standards. The tribological performance of the brake pads was analyzed using a pin-on-disc tribometer as per ASTM G-99-05. It was proved that benzoyl chloride treated Cyperus pangorei fibers based brake pads showed excellent performance characteristics compared to untreated one due to better bonding with matrix causing good contact plateaus formations as confirmed from Scanning Electron Microscopy.

“…Manoharan et al developed a new hybrid composites by using the aramid fibers. He used the recycled aramid fibers and observed that the coefficient of friction was well within the industrial range [13]. Surya Rajan et al used the Prosopis Juliforia fiber with some surface treatment and concluded that the Silane treated fibers improved the adhesive property which in turn enhanced the wear resistance [14][15][16][17][18].…”

“…It is used to convert one form of energy into another form. The brake pad generally consists of [13][14][15] ingredients which are used to satisfy the required frictional properties [1,2]. They are generally classified as Binders, Fillers, Friction Modifiers (Abrasives and Lubricants) and Reinforcements.…”

The need of the natural fibers as an alternative for existing synthetic fibers is in great demand for automotive applications. The primary objective of this work is to examine the effect of palm kernel fibers as the replacement of existing synthetic fibers. In this work the palm kernel shell fiber is added in three different weight percentages such as 0%, 5% and 10% and developed in the form of the standard brake pad as per industrial standards by keeping the Barites were used as an space filling ingredient. The various Physical, Chemical and mechanical properties were examined as per industrial standards. Chase Test Rig was used to examine the Tribological properties. Based on the evaluated Results it can be concluded that the coefficient of friction shows a decreasing value on increasing the fiber content. The Brake pad Composites containing 5 wt% of palm kernel fibers possessed high frictional value 0.454 and fade percentage was low with minimal undulations. Palm kernel fibers with 10 weight percentages showed some undulations. It can be concluded Palm Kernel Fiber with 5 weight percentage can be used as a replacement of the synthetic fibers. Scanning Electron Microscopy was used to determine the wear mechanism of the developed brake pad composites.
