Materials Used

To develop a high density brake pad for low duty application, a P/M route based on ‘Hot Powder Preform Forging’ was developed, which is not possible by sintering route. The mechanical properties of these materials were characterized using ASTM standards. The limitations of the conventional technique i.e. Compacting and Sintering for the manufacture of brake pads were tried to remove by adopting this technology. It offers better opportunity for pore free materials with better bonding between metallic and non-metallic constituents. Fade and Recovery test were done by using a Krauss Tester. μfade, μrecoveryand μperformancelie within the range of friction materials used for low duty applications.

Brake pads are important safety devices in vehicles. An effort to avoid the use of asbestos in brake pads has led to the development of asbestos-free brake pads that incorporate various organic and inorganic fillers. Palm slag as a filler in brake pads was investigated in this paper. Different processing pressures were employed during production of samples through compression molding. The properties examined included hardness, compressive strength, and wear behavior. The results showed that brake pad samples prepared with 60 tons of compression pressure resulted in the most desirable properties. Hence, palm slag has its own potential for use as a filler in asbestos-free brake pads.

Bagasse Waste

Sugarcane bagasse is one of the solid waste that can be processed as a mixture of structure materials. In theprevious research, sugarcane bagasse has been processed and used as a mixture of portland cement, the manufacture ofasbestos and also mixtures for manufacturing of brake pads that are frequently used in motor vehicle. Based on theprevious research results, it is strongly necessary to develop a research about sugarcane bagasse for structure materials.The method used to determine the mechanical properties is tensile test and compression test. To obtain the intensity ofmaterial variations, it is needed to make various sizes of filtration carbon in the form of aggregate that is mixed into thetiles material. The size of the aggregate used in concrete material can be on 200 μm, 400 μm and 600 μm. This measure istaken in accordance with the size of the filtration apparatus. Furthermore, in obtaining sugarcane bagasse carbon, theresearcher must do the oven curing process on 200 0C temperature and 3 hours in curing oven. In this research the bestresult is used bagasse powder mixtured 200 μm is 7. 2 MPa.

Asbestos-based brake pads are not desirable due to the carcinogenic nature of asbestos. Organic asbestos-free brake automotive brake pad produced from bamboo leaves was evaluated in this study. Ground bamboo leaves were sieved into sieve grades of 100, 200, and 350 μm. The sieved bamboo leaves particles were then combined with 15 % steel dust, 10% graphite, 20% resin, Silicon Carbide varied five (5) times between 35-55 % and 0-20% respectively for each sieve grade to make brake pads of different ratios. The mechanical properties (hardness, compressive strength, density, porosity, wear rate, and flame resistance) of the produced samples were investigated. The results showed that the finer the particle size of the bamboo leaves, the better the mechanical properties of the produced samples. The results of this work when compared with those of the commercial (asbestos based) brake pad showed they were in close agreement except for the wear rate and porosity property. Therefore, bamboo leaves could be used in the production of asbestos free brake pads if the wear rate and porosity properties of the produced samples could be improved.

Hot molding is one of the most important processes for the manufacture of friction materials in automotive brake systems. That is because it has direct impacts on the physical and mechanical properties. Porosity and compressibility affect properties like brake vibration. This then affects brake noise. Therefore, the objective of this work was to study the effects of hot molding conditions on the porosity and compressibility of friction materials. The crucial parameters; molding pressure, temperature and holding time were varied in the hot molding process. Porosity and compressibility were investigated and analyzed in relation to the manufacturing parameters using statistical analysis. The results and the correlation coefficients (R2) show that molding pressure and holding time are the most significant effects on porosity and compressibility. They indicate that the hot molding parameters can adequately explain porosity and compressibility.

Alpha Beta

The mechanical properties of three titanium alloys (Ti-7Mo-3Al, Ti-7Mo- 3Cu and Ti-7Mo-3Ta) were evaluated as function of: 1) Solutionizing in the beta field and aging, 2) Thermal Mechanical Processing in the beta field and aging, 3) Solutionizing in the alpha + beta field and aging. The samples were isothermally aged in the temperature range 300° to 700*C for 4 to 24 hours, followed by a water quench. Transmission electron microscopy and X-ray method were used to identify the phase formed. All three alloys solutionized at 1050°C (beta field) transformed to martensitic alpha (alpha prime) upon being water quenched. Despite this heavily strained alpha prime, which is characterized by microtwins the tensile strength of the as-quenched alloys is relatively low and the elongation is as high as 30%.
