In the modern transportation industry, the performance of braking systems is directly linked to driving safety and efficiency. As one of the core components of braking systems, the technology of composite brake pads is becoming a focal point of attention within the industry.

When dealing with complex operating conditions such as high speeds and heavy loads, traditional brake pads have gradually exposed numerous limitations. For instance, their friction coefficients are unstable, resulting in significant fluctuations in braking performance under varying temperature and humidity conditions. They also exhibit high wear rates, necessitating frequent replacements after heavy use,which increases operational costs and maintenance workloads. Moreover, their heat dissipation capabilities are inadequate, and the high temperatures generated during prolonged braking can easily lead to performance degradation of the brake pads, even posing safety risks.

To overcome these bottlenecks, researchers and enterprises are continuously exploring the technological advancement of composite brake pads. Progress in materials technology has brought new opportunities for composite brake pads. Novel fiber-reinforced composite materials have been introduced,which possess high strength and low density. These materials not only enhance the overall strength of the brake pads but also effectively reduce their weight, thereby lowering the vehicle‘s own energy consumption. Meanwhile, by precisely adjusting the proportions of various friction materials, regions with stable friction coefficients are created, enabling excellent braking force under both low-temperature, humid conditions and high-temperature, dry environments.

Innovations in manufacturing processes are also a crucial aspect of the technological advancement of composite brake pads. Advanced molding processes ensure a uniform and dense internal structure of the brake pads, reducing the problem of uneven local wear caused by internal defects. Precision machining techniques enable a higher degree of fit between the brake pads and the brake discs, resulting in more uniform contact areas, thereby improving braking efficiency and reducing energy loss.

Smart monitoring technology is also being integrated into composite brake pads. Built-in sensors can continuously monitor key parameters such as the degree of wear, temperature changes, and stress conditions of the brake pads, and transmit this data to the vehicle’s control system. Upon detecting abnormalities, the system can promptly issue warnings to remind maintenance personnel to conduct inspections and replacements, achieving preventive maintenance and significantly enhancing driving safety and reliability.

The benefits brought about by the technological advancement of composite brake pads are multifaceted. In terms of safety, stable and excellent braking performance safeguards the transportation of passengers and goods, reducing the risk of accidents. Economically, the extended service life and reduced maintenance requirements significantly lower operational costs. From an environmental perspective, more efficient braking systems help reduce energy loss during vehicle braking, indirectly lowering carbon emissions.

Looking ahead, there is still vast potential for the technological advancement of composite brake pads. With the continuous development of new energyvehicles and high-speed rail transportation, higher requirements are being placed on braking systems. Composite brake pads will move towards greater lightweighting, performance stability, and intelligence, continuously driving the transportation industry towards its green goals.
