Non-Metallic Formula Drum Brake Linings: An Overview
Non-metallic formula drum brake linings are a type of brake lining composed primarily of organic materials, resins, and fibers that do not contain metallic components. These linings are widely used in various automotive and machinery applications due to their favorable properties such as quieter operation and reduced wear on the brake drum.
The formulation of non-metallic linings is carefully engineered to optimize friction performance, thermal stability, and durability. They typically include ingredients like rubber, glass fibers, Kevlar, or other synthetic fibers, combined with binders and fillers that enhance their overall mechanical strength and heat resistance.
Combined Materials in Non-Metallic Brake Linings
The use of combined materials in non-metallic brake linings allows for tailored properties suited to specific applications. By integrating different fibers and fillers, manufacturers can achieve a balance between friction coefficient, thermal conductivity, and wear resistance.
For example, the inclusion of glass fibers improves thermal stability and reduces deformation under high temperatures, while organic binders contribute to noise reduction and smooth braking. The combination of these materials results in a lining that offers reliable performance across a range of operating conditions.
