The development of automobile brake pad using locally sourced palm kernel fiber was carried out. Asbestos, a carcinogenic material, has been used for decades as a friction material. This development has thus prompted a couple of research efforts geared towards its replacement for brake pad manufacture. Palm kernel fiber was used as an alternative filler material in conjunction with various quantities of epoxy resin as the matrix. Three sets of compositions were made, and the resulting specimens subjected to physical and mechanical tests using standard materials, procedures, and equipment. The essence is to determine their suitability and hence possible performance in service. The result showed that sample C with 40% palm kernel fiber content having hardness, compressive strength, abrasion resistance, specific gravity, water absorption, and oil absorption of 178 MPa, 96.2 MPa, 1.67 mg/m, 1.8 g/cm3, 1.86%, and 0.89%, respectively, had an optimum performance rating. It was equally ascertained that increase in the filler content had the effect of increase in hardness, wear resistance, and specific gravity of the composite brake pad, while water and oil absorption got decreased when compared with results obtained by other researchers using conventional brake pads made of other friction materials including asbestos. This is an indicator that palm kernel fiber is a possible and effective retrofit for asbestos as a filler material in automotive brake pad manufacture.

Friction material in an automotive brake system plays an important role for effective and safe brake performance. A single material has never been sufficient to solve performance related issues. Current research aimed to examine properties of Boron mixed brake pads by comparing them with the commercial brake pads. Friction coefficient of Boron mixed brake pads and commercial brake pads were significantly different and increased with the increase in surface roughness. The abrupt reduction of friction coefficient is more significant in commercial brake pad samples than in Boron mixed brake pad formulations. Fade occurred in commercial brake pad sample at lower temperatures. Boron formulations are more stable than their commercial counterparts.

This research focuses on the mechanical and effect of oil absorption on the tribological properties of carbon-based brake pad material (CBP).  Carbon-based materials, including those at a nanosize, are combined for developed brake pad material. The mechanical properties related to wear properties such as compression strength, stiffness, hardness, and absorption properties were determined. The effect of oil absorption on the tribological properties of carbon-based materials was investigated. The obtained properties are compared with that of a ceramic-made brake pad (commercial). The experimental results show that the mechanical and absorption properties of the developed brake pad material varied with the combination and quantity of additives used to develop each brake pad material. CBP material offered higher performance than ceramic-made brake pads. The CBP material showed a higher shear strength of about 110%, 51% enhanced compressive strength, 35% greater modulus, comparative statistical hardness, 98% lesser water intake, and 97% oil absorption rate than ceramic made brake pad. The tribological properties of friction material after soaked in oil proved that absorption properties affect tribological properties of brake pads, which can be attributed to the oil content in the material system. The effect of oil uptakes on wear rate and friction of the commercial brake pad was higher than CBP materials, implying that the loading of carbon-based materials is a viable way to reduce absorption rate, which helps in increasing brake pad performance. The improved properties are suggestive of materials combinations that may be used to develop brake pad materials.

The research has been conducted on the use of candlenut shells and coconut shells as composite materials in the manufacture of brake pads. The design of friction composite formulations is carried out based on four classes of friction material namely fillers, binders, reinforcing fibers and property modifiers with a fixed percentage based on weight. Comparison of the composition of Candlenut shell powder and coconut shell for each sample S-01 (35: 25) wt .-%, S-02 (30: 20) wt .-%, and S-03 (25: 15) wt. -%. From the results of data analysis, the values of water absorption for each sample were S-01 (0.00706%), S-02 (0.000496%), S-03 (0.00584%). The lowest wear test was found in the S-03 sample of 3.67 x 10-5 g / mm2.s. The SEM-EDS test results show the distribution of particles in different friction materials for each sample and show that carbon is present in approximately equal amounts in all formulations. The predominance of the presence of metals in brake linings includes: iron (Fe), magnesium (Mg), carbon (C), and aluminum (Al), silicon (Si), potassium (K)

This research is focused on the effect recycling dust (RD) on properties and performance of brake pad composites. Recycling dust was produced from grinding process of in-finishing products to standard thickness and was used as a new friction material in brake pads. Based on a simple experimental formulation, the proper type of recycling dust reused in brake pad formula was investigated by changing recycling dust type in mixing process. In the experiment, the properties of brake pads, hardness, density, porosity, and Young’s modulus were measured. Furthermore, the morphology and composition of recycling dust will be characterized by X-Ray Fluorescence (XRF), and Scanning Electron Microscopy (SEM). The developed composite brake pad showed that the value of density and compressibility increased while the value of hardness and Young’s modulus decreased by adding 10wt% of recycling dust to commercial brake pad formulation. Hence, the benefit of this work is using recycling dust as one of alternative fillers in disc brake pad materials without compromising the quality and performance.

Effect Of Particle Size

This study aims to determine the effect of particle size and material composition on the performance of resin-based brake pads. Experiments were carried out by mixing 75% UPR with durian peel and banana midribs fibers using ratios of 1/1, 3/2, and 2/3 at particle sizes of 104 and 250 μm. The experimental results shows that decreasing the particle size improves the mechanical properties of brake pads, but gives a high wear value and a low coefficient of friction. In addition, an increase in the percentage of banana midrib fibers as a whole provides better brake pad performance. The results of the comparison between commercial-based brake pads confirm that agricultural waste is potential as an alternative to friction materials in brake pads. Brake pad with a fiber ratio of 2/3 104 μm had highest values of hardness, wear and friction coefficient, namely 20.33 N/cm3, 2.02 x 10-4 g/s.mm2, and 0.2465. while the 1/1 250 μm and 3/2 250 μm had the lowest coefficient values and compressive strength of 0.1195 and 9.14 N/cm3. This study demonstrates the use of biomass waste as an alternative to friction material to overcome the dangerous problem of using asbestos in brake pads.

Thermal Stability Of

The formulation of a brake pad requires the optimization of multiple performance criteria. To achieve a stable and adequate friction (µ), the brake pad materials should have low fade and higher recovery characteristics coupled with less wear and noise. Among the properties mentioned, resistance to fade is very difficult to achieve. The type and amount of resin in the friction material is very critical for structural integrity of the composites. The binder should not deteriorate under any diverse conditions. The thermal stability of friction materials and its capacity to bind its ingredients collectively under diverse conditions depend upon the quality and proportion of resin. The current work evaluates the fade and recovery behaviour of developed friction composites from two different resins which are traditional straight phenolic resin and the alkyl benzene modified phenolic resin. Two brake pads with these different resins were fabricated as per Industrial Standard. TGA is carried between 150 – 4000 C as this zone of temperature is very critical which accounts for the weight loss (Thermal degradation). Friction and wear studies were carried out on a friction coefficient test rig as per SAE J661a standard. The results showed that the fade and wear of the friction materials were closely related to the thermal decomposition of the binder resin and durability of the contact plateaus, which were produced by the compaction of wear debris around hard ingredients on the rubbing surface. It was clearly observed that the friction materials with modified resin showed significant reduction in fade %. Friction materials made with higher thermal stability showed resistance to fade. However wear didn’t show much noticeable changes.
