Oil Rig Brake Pad Material Evolution and Technological Breakthroughs

Material Development History

From Early Asbestos-Based Materials (Before the 1980s) to Modern Composite Materials:

First Generation: Asbestos Resin (Obsolete)

Second Generation: Semi-Metallic Sintered Composites (1980-2000)

Third Generation: Ceramic Fiber-Reinforced Composites (Current Mainstream)
