Introduction to Friction Plates

It is a key component used in mechanical transmission and braking systems to transmit or block power, and its types and classifications are based on various standards. The following is a detailed classification explanation:
Classified by application field**
1. * * Brake friction pad**
-Car brake pads: disc type (in contact with the brake disc) and drum type (in contact with the brake drum).
-Train brake shoes: Used for train braking systems, they need to withstand high pressure and high temperature.
-Industrial brake pads: Used for equipment such as machine tools and cranes, emphasizing wear resistance and high temperature resistance.
-* * Aviation brake pads * *: Carbon/carbon composite material, high temperature resistance (up to 2000 ℃ or above).
2. * * Clutch friction plate**
-* * Automotive clutch plates * *: dry (for ordinary vehicles) and wet (for motorcycles or high-performance vehicles).
-Industrial clutch plates: Used for construction machinery or heavy equipment, requiring high torque transmission capacity.
-Wet clutch plates for motorcycles: Oil immersed operation, good heat dissipation, and long service life.
-Classified by material**
1. * * Asbestos based friction pads**
-* * Characteristics * *: Low cost, high temperature resistance, but carcinogenic, gradually phased out.
-* * Application * *: Old style vehicles or low-end industrial equipment.
2. * * Half metal friction plate**
-* * Material * *: Metal fiber (steel, copper) mixed resin.
-* * Features * *: Good heat dissipation, wear resistance, but high noise.
-* * Application * *: Ordinary car disc brake pads.
3. * * Ceramic based friction pads**
-* * Material * *: Ceramic fiber, mineral fiber, adhesive.
-* * Features * *: Low noise, high temperature resistance, no metal dust.
-* * Application * *: High performance cars or racing cars.
4. * * Organic Friction Plates (NAO)**
-* * Material * *: Glass fiber, aramid fiber, resin.
-* * Features * *: Environmental protection, low noise, but poor high temperature resistance.
-* * Application * *: Family sedan.
5. * * Carbon fiber/carbon ceramic friction plate**
-* * Features * *: Ultra light, high temperature resistance (above 1000 ℃), extremely high cost.
-* * Applications * *: Aerospace, top sports cars (such as Porsche, Bugatti)
