Sepiolite: A new component suitable for 380 km/h high-speed rail brake pads

In a recent study published in the journal Advanced Powder Materials, the traditional powder metallurgy compaction and sintering method was employed to produce sepiolite-reinforced copper-based brake pads, while carbon-ceramic composite brake disks were prepared using chemical vapor infiltration and melt infiltration techniques. The manufactured brake pads not only met the mechanical strength requirements for high-speed train brake pads but also exhibited minimal wear and stable frictional braking performance at high temperatures.
