In the complex field of brake pads manufacturing, the materials chosen are crucial for guaranteeing stable braking performance and vehicle safety. Garnet Powder, with its special physical and chemical features, has become an important part in brake pads production, bringing both advantages and disadvantages.

Garnet, a group of silicate minerals with the general chemical formula A₃B₂(SiO₄)₃, where A could be calcium, magnesium, iron(II), or manganese, and B might be aluminum, iron(III), chromium, or vanadium. Once processed into powder, Garnet Powder shows properties that matter a lot in brake pads production. Its density usually ranges from 3.5 – 4.3 g/cm³, which affects the weight and balance of the brake pads. With a Mohs hardness between 6.5 – 7.5, it’s hard enough to influence the friction of brake pads.

When making the brake pads mixture, Garnet Powder is mixed with different components. Phenolic resins, for example, are used as binders to hold the mixture together. They offer the necessary cohesion to keep Garnet Powder and other ingredients in one structure. Fillers like kaolin or graphite are added to adjust the mechanical and thermal properties. In a typical brake pads mix, Garnet Powder usually makes up 5 – 15% by weight. This proportion is carefully decided to get the best performance from the brake pads. For example, increasing the amount of Garnet Powder can raise the friction coefficient, but if not balanced well with other elements, it might affect the wear resistance and cause more noise during braking.

As a key part of brake pads friction materials, Garnet Powder is very important in determining the friction and wear. A well – designed friction material with the right amount of Garnet Powder can keep a friction coefficient between 0.4 – 0.6 under normal braking. This coefficient is essential for a stable and strong braking force. Whether it’s a small car or a big commercial vehicle, the consistent friction from brake pads with Garnet Powder helps ensure reliable braking.
