What Are the Main Raw Materials of Brake Pads?
1 Answers
The main raw materials of brake pads are adhesives, reinforcing fibers, fillers, and friction modifiers. Below is a detailed introduction about them: 1. Adhesives include resins and rubber powders: Their function is to liquefy and then solidify at high temperatures, turning the brake pad from powder into a solid block. 2. Reinforcing fibers serve as the skeleton of the brake pad: These include aramid fibers, steel wool fibers, copper fibers, mineral fibers, ceramic fibers, potassium titanate whiskers, etc. 3. Fillers: Different raw materials of brake pads have varying mesh sizes and diameters, requiring certain gaps to be filled. 4. Friction modifiers increase friction: These are materials harder than the brake disc, such as aluminum oxide, zirconium silicate, brown corundum, etc.
