The Science Behind High Friction Non Asbestos Woven Materials
The performance of a brake lining is fundamentally a matter of material science and mechanical engineering. Non asbestos woven brake lining is a complex composite that relies on the synergy between reinforcing fibers binders and friction modifiers. In our manufacturing facility we select high performance fibers like aramid which is known for its incredible heat resistance and tensile strength to serve as the backbone of the lining. These fibers are woven together in a multi layer structure that creates a dense yet flexible matrix. This weaving process is critical as it allows the lining to maintain its structural integrity even as it wears down during years of heavy use in industrial braking applications.
The resin system used to bond these fibers is equally important to the final performance of the brake lining. We use high temperature phenolic resins that undergo a precise curing process to ensure that the lining remains stable under extreme thermal stress. These resins are formulated to provide a consistent friction coefficient across a wide range of temperatures and pressures. Without a high quality binder the fibers would simply pull apart during the high shear environment of a braking event. Our proprietary resin blends also include lubricants and friction enhancers that help to stabilize the stop and reduce noise and vibration which are common issues in heavy duty industrial braking.
One of the unique aspects of woven linings is the inclusion of metallic wires usually made of brass or zinc. These wires are not just for strength; they play a critical role in the friction dynamics of the material. As the brake engages the metallic elements help to clean the mating surface of the brake drum or disc preventing the buildup of glaze and debris. This self cleaning action ensures that the friction level remains high and consistent throughout the life of the lining. Furthermore these wires act as heat sinks drawing thermal energy away from the friction surface and distributing it through the body of the lining to be dissipated more effectively into the atmosphere.
The wear characteristics of non asbestos woven brake lining are a result of the careful balance between the hardness of the fibers and the softness of the resin. A lining that is too hard will cause excessive wear on the expensive brake drums while a lining that is too soft will wear out too quickly. Our engineering team has perfected this balance to ensure that our linings offer a long service life while being gentle on the mating machinery. This sacrificial nature of the brake lining is a key design feature that protects the larger more expensive components of the braking system from damage during high energy stops in mining construction and oilfield equipment.
As a manufacturer we are constantly researching new fiber combinations and resin chemistries to improve the performance of our non asbestos products. The transition away from asbestos was just the beginning; the current focus is on enhancing the environmental profile and the energy efficiency of friction materials. By using advanced manufacturing techniques like computer controlled looms and precision curing ovens we produce woven linings with unmatched consistency. Our commitment to scientific excellence ensures that every roll of lining we produce meets the highest international standards providing our customers with the most advanced friction technology available today for their critical industrial needs.
