Discontinuously Reinforced Aluminum Composite and Its Application in Brake Discs

“…However, there are also some barriers for widespread applications of the DRA composites in automotive industry. Firstly, because some properties of DRA composites differ vastly from those of cast iron, the new design and optimization for the construction of the brake disc itself is necessary while temperature limitations on DRA discs exist [3]; Secondly, because the brake performance is dependent upon brake disc/pad interaction, the use of new materials for the brake discs requires a corresponding development of compatible brake pads [4], their friction and wear performance must match with each other; Finally, the most important factor that has restricted the widespread use of DRA composites has been their relatively high cost over traditional materials up now. In a word, although lots of achievements have been reached upon DRA discs, there is still a long way to go for a widespread use in automotive industry.…”

Deformation map for hot working of AA2024 composites reinforced with SiC particle

“…Al-based composites reinforced with particles, whiskers or short fibers have emerged as advanced materials owing to their good wear resistance, high specific strength, and low thermal expansion properties [1,2]. Similar to unreinforced monolithic alloy, the conventional hot working processes such as rolling, forging, and extrusion can be used to produce the composites products.…”
